Chapter Six: Reference A Tip About Using The Reference Section The Reference section, as its name suggest, is not intended to be read straight through. Instead, refer to this material when you want or need more information about a particular program feature or function. When you want more information about an feature, you can look it up in the Index and then find it in Reference, or look immediately in the Reference for the part of Deluxe Video III that you're using. OVERVIEW Deluxe Video III is a collection of four versatile programs that let you combine different kinds of data to make complete audio-video presentations. The programs are DVMaker, DVMover, DVPlayer, and InstantSlideShow. Each program has an important and unique function in creating and playing Deluxe Video III presentations. ° DVMaker lets you introduce sounds, images, and animations, (all referred to as Parts) that have been created with other Amiga programs, and combine them into a coordinated presentation called a video. ° DVMover copies videos and associated data files to another disk. ° DVPlayer plays videos. ° InstantSlideShow can quickly create a video which displays a series of pictures. Each Deluxe Video III program has its own reference section; and each is organized so similar options and features are located close to each other. PARTS A Part in DeluxeVideo III is any object or piece of data used in a video. Parts are such things as pictures, sound effects, or animations created in DeluxePaint III. These Parts are then put together using DVMaker to form a complete video, which controls how the Parts are introduced, presented, and removed. Rather than combining all of the data in a video into one large file, each Part is saved as a separate file on disk. When a video is played, DeluxeVideo opens the file and loads the Part into memory. This lets yo make changes to any Part without haveing to rebuild the video. For example, you can make a sketch of a background picture in DeluxePain and then create a video using that picture. After you've created the video, you can go back to DeluxePaint and complete the sketch; the video will then play just as before, but with the newly finished picture. Keeping all of the Parts in separate files, while it makes modifying them easy, means that DeluxeVideo III must know where they are to load them. That's why DeluxeVideo III always records the full drawer specification for every Part you use. Having each Part in a separate file also complicates the task of copying a video to a different disk. In addition to copying the video file itself, you must copy each Part file used in the Video, and the drawer specification for each Part must be changed. The best way to do this is to use the DVMover program to move videos from one disk to another. When a Part is loaded, Deluxe Video III tries to open the file with the drawer specification listed in the video. If this fails, DVideo III tries again for every drawer in the "search path." PART TYPES There are 7 different Part types in DeluxeVideo III. Each Part type is explained below. ANIM An Anim is an animated picture created by DeluxePaint III or other Amiga software that uses the Anim standard file format. ANIMBRUSH An AnimBrush is an animated brush created by DeluxePaint III. BRUSH A Brush is a standard IFF file of any size or resolution mode. Normally this is a raster saved as a brush by DeluxePaint or other paint program. INSTRUMENT An Instrument is an IFF8SVX file of a musical instrument compatible with DeluxeMusic or Instant Music. PICTURE A Picture is an IFF file of any size or mode. Normally, this is a full screen raster saved by a paint program such as DeluxePaint, but it can also be a brush that is smaller than 320x200. If the picture is a tilte surrounded by a region of color 0, you can save it as a brush and use it as a picture in DeluxeVideo III, thus using less Chip memory. SOUND A Sound is an 8SVX file containing a sampled sound. TUNE A Tune is an IFF SMUS file created by Deluxe Music, Instant Music or other Amiga program. Up to eight tracks of music are supported by Deluxe Video III. DVMAKER Because DVMaker is the heart of DeluxeVideo III, you shuld understand, in detail, how it works and how it relates to the other parts of the program. DVMaker can combine pictures, animations, sound effects and music to make a complete video presentation. The raw materials of DVMaker are pictures drawn in programs like DeluxePaint III, and music composed in a program like DeluxeMusic. DVMaker lets you combine these separate data elements any way that pleases you. The result is a video, which you can play back on your Amiga, record on videotape, or broadcast as a live video signal. HIERARCHY When you load the DVMaker program, the basic Video Script appears. This Video Script is a graphic representation of a specialized shooting script on which you position the various elements of your video. It's the highest level of the hierarchical structure that DeluxeVideo III uses to organize diverse data elements for your video. A Time Line runs across the top of the screen, and tracks that control various data elements in DeluxeVideo III appear on the left (View and Video). These tracks are like the sound or music tracks in a movie. On each track you can position effects (like Scene on Video track). Effects give you precise control over how the data on each track is presented, and when the data begins or ends. Within a given track you can place any number of scenes, which are more detailed representations of the tracks and effects within a portion of the video. In short, a complete video consists of a Video Script, which has a number of tracks. Within the Video Script there may be several scenes, and each of these may have its own Scene Script and accompanying track(s). Finally, you can place effects on both the video and scene tracks, which control the nature and timing of the events that occur in the video. The information in this Reference section reflects the hierarchical order of DeluxeVideo III. EXECUTION ORDER The order of evenets (that is, tracks and effects) in a Video or Scene Script is important, because you'll usually want the elements of your video to play in a precise sequence. A cue to execution order is how the track and effect boxes appear on the screen. The effects are drawn in the order they'll be executed. DeluxeVideo III follows these rules when it plays a video: ° The effect with the earliest start time starts first. ° If start times are the same, the effect on the highest track starts first. ° If effects are on the same track, the leftmost effect start first. ° If the effects boxes are in the same horizontal position on the same track, the effect with the highest vertical position on the screen starts first. ° If all of the above factors are the same, the effect added first is executed first. DVMAKER - SCRIPTS DVMaker uses two kinds of scripts, the Video Script and the Scene Script, to display your work. The Video Script is a high level description of the complete video action and the Scene Script is a detailed description of what goes on in a given part of the video, called a scene. VIDEO SCRIPT The main screen in DVMaker is a graphic representation of a shooting script, which displays the events that make up a video. This representation is called the Video Script. It consists of tracks, effects, and scenes, which may contain Scene Script. ADD AREA The Add Area contains a Track icon (on the left) and an Effect icon (on the right). Use the Add Area to create (add) new tracks and effects to a Video Script. TRACK AREA This is where you place new tracks. Each track has an icon that represents its type, and a name describing the track. Every track has three main sections. ° Attach Box ° Drag Box ° Time Line You can move tracks by clicking on the Drag Box, holding down the mouse button, and dragging the track to a new location. * The Attach Box functions only in tracks in a Scene Script. ADDING A TRACK TO YOUR VIDEO To create a new track for your Video Script: > Press and hold down the left mouse button on the Track icon in the Add Area. > Drag the (blank) track down into the Track Area and release the mouse button. A requester displaying the types of available tracks appears. * You can select Expert mode to see the greatest number of track types. (See Expert under the Options Menu, below). > Click on the type of track you want (or click Cancel to return to the Video Script). If the type of track you select requires that you add data to the video, the Parts requester appears automatically. See Parts Menu, below for more information on this requester. > Click on the data you want from the Parts requester. > Click the Selct button to confirm your choice(s). The Parts requester disappears and the track (the data) is added to the video. EFFECT AREA Video effects are placed on tracks in the Effect Area. Each effect has a name and arrows indicating its start and end times. You can move effects by dragging the name area of the box. You can also drag the start and end arrows to move them. ADDING AN EFFECT TO YOUR VIDEO To create a new effect for a track in your Video Script: > Press and hold down the left mouse button on the Effect icon in the Add Area. The Time Window appears over the Track Area of the script. > Drag the outline of the blank Effect icon into the Effect Area and position its "flag pole" over the Time Line of the selected track where you want the effect to occur. > When you've positioned the effect, release the mouse button. A requester displaying the types of available effects appears. * You can select Expert mode to see the greatest number of effect types. (See Expert under the Options Menu, below.) > Click on the type of effect you want (or click Cancel to return to the Video Script). TIME WINDOW When you drag an effect, the Time Window appears over the Track Area of the script. This indicates the start (S), end (E), and duration (D) times of the effect you're dragging. The units in the window are (MM=Minutes, SS=Seconds, JJ=Jiffies [1/60th of a second]). Times are displayed in the units you've set in the Video track. Use the readings in the Window to accurately position the effect in the script. When you're in the Video Script, it shows times relative to the video; when you're in a Scene Script, it shows times relative to the scene and to the video. TIME BAR The Time Bar shows the time taken by the effects, with the time increasing from left to right. TIME SCALE BUTTONS These buttons allow you to increase or decrease the amount of time displayed in the Time Bar. Click on the + to increase the amount of time displayed; click on the - button to decrease the amount of time displayed. SCRIPT CAPACITY GAUGE This gauge shows the relative amount of the memory buffer used for the Script you're reading. You can change buffer sizes by selecting Memory>Buffer sizes...from the Options menu. TRACKS A track defines what the video presents. There are six types of tracks in Deluxe Video III: ° Setup (Video and View) ° Audio (Sound and Tune) ° Control ° Expert (Background, Device) ° Object (AnimBrush, Box, Brush, Textline) ° Viewport (Backdrop, Anim, Picture) In the Video Script, only four track types are available:Setup, Audio (the Tune track only), Control, and Expert tracks. See Tracks and Effects in the Video Script, below. In the Scene Script, Audio (the Sound Track only), Control, Effect, Object, and Viewport tracks are available (see Tracks and Effects in the Scene Script, below). * To create a new track in either a Video Script or a Scene Script, see Adding a Track to Your Video under Track Area above. Unless otherwise noted, your video can have up to 255 tracks of any track type. All tracks share three common elements: the Drag Box, the Time Line, and the Attach Box. Because the Attach Box functions only in tracks in a Scene Script, we'll discuss it under the section Tracks and Effects in the Scene Script, below. DRAG BOX Move a Track - Use this area of a track to move the track. > Place the pointer over the Drag Box of the track you want to move. Press and hold down the mouse button. > Drag the track up or down in the Video Script. > Release the mouse button to position the track at the new location. TIP: To move a track and all tracks below it, hold down the left Amiga key while dragging the track. TIME LINE This portion of the track extends into the Effect Area. This is where effects are placed on the track, showing their beginning and ending times, and duration. EFFECTS Creating an Effect An effect defines how a track acts. You create an effect by dragging the Effect icon down from the Add area and releasing it over a track in the Effect Area. Some effects display an effect requester when you select them, where you can specify exactly how the effect works. In this Reference, each effect requester is described in the section about the effect itself. To change the start time of an effect, press the mouse button down on the Start arrow and drag it left or right; the end time moves with the start time. Holding down the left Amiga key while you drag the start time moves all effects on the TRACK with a start time later than or equal to the start time of the effect you're dragging. Holding down the right Amiga key moves all effects in the SCRIPT with the same or later start time. To change the end time, press the mouse button down on the End arrow and drag it left or right. To change both the start and end times while keeping the duration constant, press the mouse button down on the Drag Bar and drag the entire effect left or right. To re-position the effect without changing the start or end time, press the mouse button down on the Name Box and drag the effect. * Some effects are instantaneous and have no end arrow. TRACKS AND EFFECTS IN THE VIDEO SCRIPT There are three types of tracks that can appear in a Video Script: ° Setup (Video and View) ° Audio (Tune) ° Expert (Background, Control, and Device) Here we'll describe these tracks (in alphabetical order) and their associated effects. BACKGROUND TRACK Background is an Expert track, which is used to manipulate multiple viewport effects (see Appendix A). Only one Background track can appear in the Video Script. Probably the only time you'll need a Background track is in a scene in an interactive video. If you have a screne the user can GoTo, you may need a Background with Hide and Purge effects to free up memory used in the secne from which you came. * Background tracks are only available after you select Expert from the Options menu. As with other Expert tracks, you can place Background tracks in both Video and Scene Scripts (one for each Script). You can't attach Background tracks to other tracks. BACKGROUND EFFECTS HIDE Makes all but the frontmost viewport invisible. If you have several visible viewports, it's just like having a Hide effect on each one. PURGE Does an Unload effect on all hidden viewports and discards all unused Parts to free up more memory. CONTROL TRACK Only one Control track can appear in the Video Script. You can use it to control the speed and sequence of the video. In particular, the Control track lets you make an interactive video. Effects available for the Control track include, maong others, KeyTo, which lets you choose the video or scene to display next; and Button, a combination of GoTo and Wait, which lets you click on any object in the middle of a video to display a new video or scene. CONTROL EFFECTS BUTTON A Button effect can duplicate any one of the actions and modes of the Control Panel (see Control Panel in this Reference section). When you choose this effect, the Control Panel Button requester appears. Click the appropriate check box to select what you want. Click the On box to activate a Modes selection. The Joystick and Tune videos on the DVExamples disks each contain an example of a Button effect. See Chapter 5, Video Effects, for more information. GOTO This effect causes the video to jump to the beginning of another video, a scene, or a Label. If the Video box is not selected, the program looks for a scene that matches the letters in the name (regardless of capitalization) specified in the GoTo requester. If it doesn' find that scene, it looks for a matching Label within the current scene. Video If this box is selected, the Name is interpreted as the name of a video. If it's off, the Name is interpreted as the name of a scene or a Label. Name Click here and type in the name of the video, scene or Label you want to go to. The path name isn't required if the video is in the same drawer as the video currently running. JOYSTICK If you've attached a joystick to Port 2 on your Amiga, you can use this effect to specify what video or scene to go to next, based on the movements of that joystick. If the Video box is not selected, the program looks for a scene that matches the name (case insensitive) specified in the Joystick requester. If it doesn't find that scene, it looks for a matching Label within the current scene. The Joystick video on the DVExamples1 disk contains an example of a Joystick effect. See Chapter 5, Video Effects, for more information. Waiting If this box is selected, the video waits for the time specified (in seconds) in the box for you to move the joystick. If no motion is detected the video resumes playing at the point of the effect. Click the up or down arrows to change the time, or click in the time box and type in a time. Video If this box is selected, the Name is interpreted as the name of a video. If it's off, the Name is interpreted as the name of a scene or a Label. Name Click here and type in the name of the video, scene or Label you want to go to. The path name isn't required if the video is in the same drawer as the video currently running. The four directional boxes display the choices you can make by moving the joystick. The fifth box, Button, refers to the joystick's firebutton, which you can use to issue a GoTo effect. KEYTO This effect causes the video to jump to the beginning of anohter video, a scene, or a Label, depending on the key you press. If the Video box is not selected, the program looks for a scene that matches the name (case insensitive) specified in the KeyTo requester. If it doesn't find that scene, it looks for a matching Label within the current scene. Waiting If this box is selected, the video waits for the time specified (in seconds) in the box for you to press a key. If no key is pressed, the video resumes playing at the point of the effect. Click the up or down arrows to change the time, or click in the time box and type in a time. Key You can enter up to 8 different keys to wait for by clicking in the Key box and typing the key(s) you want to use. The keys are case sensitive. Video If this is on, the Name is interpreted as the name of a video. If it's off, the Name is interpreted as the name of a scene or a Label. Name Click here and type in the name of the video, scene or Label you want to go to. The path name isn't required if the video is in the same drawer as the video currently running. LABEL This effect, which is not available in the Video Script, provides a reference point for a GoTo or a KeyTo effect. Placing the Label effect means that the appropriate GoTo or KeyTo will start at this point (see GoTo and KeyTo effects above). Labels can only be added within a scene. When you create this effect, the Index requester appears. PANELON Turns on the Control Panel for the duration of the effect. This is a useful effect when you're debugging your videos. POINTER Turns on the mouse pointer for the duration of the effect. TIMESTEP Temporarily changes the time step of the video (in jiffies). The default is 2 (jiffies), which equals 1/30th of a second. WAIT Causes the video to wait for the indicated time (in seconds) before proceeding. The default is 60 seconds. To change the Waiting time, click the Waiting time box, set a different number in the seconds box, and click OK. If you use Wait in conjunction with GoTo effects on Brush tracks (See GoTo in the Effects list for the Scene Script, later in this chapter), you can control the video by clicking the mouse on an object. See the description of the MultiMedia example video in Chapter 5, Video Effects, for more information about Wait. DEVICE TRACK Device is an Expert track, intended for advanced users, which lets DeluxeVideo III communicate with an external device such as a genlock or a videotape recorder. * Device tracks are only available after you select Expert from the Options menu. As with other Expert tracks, you can place Device tracks in both Video and Scene Scripts. You can't attach Device tracks to other tracks. You may need to do some programming to meet the requirements of your particular hardware, but this gives expert users the flexibility they need. To control an external device, DeluxeVideo III sends messages to another program that actually does the controlling. The messages are sent via an ARexx compatible message port. * Electronic Arts cannot provide technical or ARexx programming support Device track users. To use the Device track, see Appendix C: Using ARexx, below. When you creat a Device track, a requester asks you for the Port Name (the ARexx message port). Click in the window and type the appropriate port name (specified in your control program). Under Device Options, click the Critical box if you want the video to stop if the port fails to open. DEVICE TRACK EFFECT MESSAGE This effect sends one or more ARexx compatible messages to the message port named by the Device track. When you create this effect, the Message requester appears. Message Text Enter the text of the message here by clicking in this box and typing. Typically, this is the name of a device command as specified in the device control program. Message Options Click the check boxes to choose these options (a highlighted check box is active). Wait For Reply means that DeluxeVideo III will wait for a reply from the device control program before continuing. Failure Is Fatal means that the video will stop if the device control program returns an error code. Time Out While Waiting is used with Wait For Reply to make the Video pause until the device responds. No Duration is used when the message is a command that is performed instantly; if this option if not checked, a continuous stream of messages is sent for the duration of the effect. TUNE TRACK Tune is a SMUS IFF file in a video. When you click Tune in the Choose a Track requester, the Parts requester appears. Find the tune you want in the On Disk window and click on it. If this is the first time you've loaded the selected tune in the current video, the Load these Instruments? requester appears. Click Yes to load the listed instruments, and then click Select to add the selected Tune track to your video. If you want the end of your Tune to coincide with an event that takes place within a scene, determine the time inside the scene and then use that as the end time of the Play effect on the Tune in the Video Script. * You cannot place a Tune track in a Scene Script, nor can you attach a Tune track to any other track. TUNE TRACK EFFECTS LOAD This effect opens the Tune file and loads it into memory, so when you want to play the Tune there's no delay for file loading. Use this effect sometime before a Play (Tune) effect. This makes the video run more smoothly because the program doesn't need to pause while the Tune loads. Load doesn't have a requester. Simply place the effect where you want it. PLAY Plays the selected Tune. When you create this effect, the Play Tune requester appears, where you can adjust how the Tune plays. Adjust any of the sliders by clicking on the arrows to the left and right of the slider or by dragging the bar in the slider to the position you want. Tempo Select this box to play the Tune at the tempo shown. The tempo ranges from 1 to 511 quarter notes per minute and can be adjusted with the slider. Volume If this box is selected, DeluxeVideo III uses the volume value at the right (from 0 to 127). Repeat Select to play the Tune repeatedly the indicated number of times. Continuous If this box is selected, the Tune is repeated for the duration of the effect. This is the recommended setting, because it's very difficult to synchronize a Tune with a Script. Preview Click on this to hear the Tune and test your settings. Click again to stop the Tune. Click OK to accept the settings and return to the Video Script; or click Cancel to return to the Video Script without changes. * You'll notice that Position, Priority, and Stereo are grayed out in the requester. Those three settings are used in Sound tracks. They are not used in a Tune track and cannot, therefore, be selected. UNLOAD This effect unloads the Tune and frees up the memory it was using. If the video has many Parts or Scenes, it's a good idea to Unload when the Tune is no longer being used. VOLUME This effect displays the Volume requester, where you can change the volume of the Tune while it's playing. It's a good idea to reduce the volume of a Tune just before the end of a Continuous Play effect. Type in the volume value (from 0 to 127), use the slider, or click on the arrow keys to change the value. Click OK to accept the new value and return to the Script, or click Cancel to return without changes. VIDEO TRACK When you boot DVMaker or create a new video (using New from the File menu), a Video track with an empty Scene effect is automatically created. A Video Script may have only one Video track. You can attach scenes to this track. * A Video track is never allowed in a Scene Script. To manipulate the Video track, double-click on the Video track's Drag Box to display the Video requester. Video Name Displays the name of the current video. To change the name, click in this window and type. If you change the name of the video here, it's saved under the new name (when you save it). Time Units This area sets the display mode for any times shown in the video. Click on the appropriate check box to activate the option (the active option has a highlighted check box). Choose HH:MM:SS.JJ to get hours, minutes, seconds, and jiffies; click Frames to display times in 1/30th of a second (1/25th for PAL version Amigas); click jiffies to display times in 1/60th of a second (1/50th for PAL version Amigas). Display Defaults Whenever you create a Scene effect, it has some default values. You can change these values within a scene, using the Expert effect options, or you can click on the scene to highlight it and use the Change option in the Scene menu to do the same thing. Double Buffer is necessary for flicker-free brush animation, but it doubles the amount of memory required by the viewport. Restore Black restores the background to color 0 as the brush moves over it. Save & Restore displays any background underneath a moving brush. Timing This controls how DeluxeVideo III copes with any timing problems it encounters while playing a video. Click the checkbox to activate the option. Realtime means that the video clock runs continuously, and DeluxeVideo III tries to catch up if it falls behind while displaying or loading data. Use this option only if you're trying to synchronize music with video action, and you're playing a very simple animation. Realtime works best if you're using a fast processor, like a 68030. The I/O Time Out option menas that the clock is stopped while DeluxeVideo III reads data in from disk. This option is strongly recommended. The Time Step option shows the amount of time between display frames, in jiffies. Click the up or down arrows to adjust this. This value should be set at 2 for most videos. Control Turn these four options on or off by clicking on the corresponding check box. Loop forces the video to play over and over again, starting each time at the beginning of the video. Lock Control prevents a user from interrupting the video by accidentally hitting the keyboard or clicking the mouse. This is useful for demos or training videos that you supply to others. Lock Control works only when a video is played by DVPlayer. Mouse Skip lets you use the mouse buttons to skip scenes in a slide show. Use the left mouse button to skip to the next scene. Use the right mouse button to skip backward to the previous scene. Keep Parts means that the parts are not automatically discarded when the video lopps back to the start. Click OK to accept the changes and return to the Video Script, or click Cancel to return to the Video Script without changes. VIDEO TRACK EFFECT SCENE Only Scene effects can be placed on a Video track. Whenever you drag an effect from the Add Area to the Video track, that effect automatically becomes a Scene effect. These Scene effects can't overlap. Double-click the Scene effect to create and enter the Scene Script, where you can specify precisely the actions of the ivdeo. See Scene Script below for a description of the features available in the Scene Script. VIEW TRACK When you boot DVMaker or create a new video (using New from the File menu), a View track with a Show effect is automatically created. A Video Script may have only one View track. You can attach scenes to this track. A Vie wtrack is present in every Video Script, but you can't add a View track to a video. This track controls the maximum size of any Viewport displayed during the video. Double-clicking on the View Drag Box displays the View requester, where you can set the parameters for the video. * A View track is never allowed in a Scene Script. Size Lets you set the overall maximum size of the video in LoRes units. Click on the up or down arrows of the Width or Height boxes to change the values (in pixels), or click directly in the box and type in new values. The value limits are 352 x 240 (352 x 290 for PAL) unless you're an expert user. If you're in Expert mode, the maximum value are 416 x 336. Click the Normal buttom to get the standard LoRes values, and click the Overscan button to get the standard overscan values. If you're going to show a 704 x 480 HIRES LACE overscan picture, set the sizes to 352 x 240. Offset Lets you set the number of pixels that the screen is offset from the origin. Click on the up or down arrows of the X or Y boxes to change the values, or click directly in the box and type in new values. Offset limits are x+16 and y+10 unless you're in Expter mode, in which case it's x+32 and x+20. You can use this option to center the view on your monitor. Only experts should set values outside the range +16. Options Click this check box to get an interlaced view regardless of the mode of the viewports being displayed. Use this option whenever you're recording a video onto videotape or broadcasting it. SHOW Activates the view track settings for the entire video. Show cannot be deleted or opened, and is present in all videos. It's a non-erasable default effect. SCENE SCRIPT A video is comprised of one or more scenes, each with its own script. The Scene Script represents the next level down in the video hierarchy and is similar to the Video Script in a number of important respects. Scene Scripts are visually identical to Video Scripts with two exceptions: a Close Scene button appears above the Add Area (click this button to close the Scene Script and return to the Video Script), and the Time Bar shows two sets of time lines. The upper time line is for the Video Script, and the lower time line is for the Scene Script. Like a Video Script, a Scene Script can have its own track(s) and effect(s). To open an existing scene on the Video track, double-click on the Scene effect. Whenever you add a scene ( a Scene effect) to the Video track (by dragging down the outline of a new effect the to the Video track Time Line), the Scene Script opens automatically. The Scene Script is the storyboard of the video, where you designate the exact data you want in the video; how it appears, how it's presented; and how it's removed. If you have a complex video with many different types of data presented in sequence, it's helpful to put that data into several scenes to make the organization simpler and allow you to manipulate the video more easily. TIP: Because Scene Scripts share several common elements with Video Scripts, such as tracks and effects, the general track and effect information that appears in the Video Script section above (what tracks and effects are, how to add or move them, etc.) is not repeated here. You may want to consult those sections of hte Reference for more information. Here we'll concentrate on track and effect details that relate only to scenes. When you add a track to the Scene Script, there are five types of tracks from which to choose: ° Audio (Sound) ° Expert (Background, Device) ° Control ° Object (AnimBrush, Box, Brush, Textline) ° Viewport (Backdrop, Anim, Picture) We'll describe these tracks (in alphabetical order) and the corresponding effest they support. TRACKS You probably remember that all tracks share three common elements: The Drag Box, the Time Line, and the Attach Box. We discussed the Drag Box and the Time LIne under Video Script, above. Here we need to describe the Attach Box, because tracks in the Scene Script (with the exception of Expert, Control, and Sound tracks), can be attached to one another. Attaching one track (1) to another (2) is a simple way of making (1) follow the movements that you've specified for (2). Any new movements you program for the attached track (1) are relative to the movements of the base track (2). ATTACH BOX Use this area to attach one track to another. Any Object track is automatially attached to the nearest Viewport track above it in the Scene Script. The Attach Box shows a visual representation of the track type. * You can't Attach Audio or Expert tracks to other tracks or to one another. If you click on the Attach Box of one of these track types, a Problem requester states Error 303: Can't attach to this track. To Attach one track to another: Attach a Track > Place the pointer over the Attach Box of the track to be attached. > Press and hold down the mouse button; Attach to appears beneath the pointer. > While holding the button down, move the pointer to the Attach Box of the track to which you want to attach the first track. > Release the mouse button to attach the track. ANIM TRACK An Anim track presents a compressed animation sequence in the IFF standard format called Anim. These Anims can be created by DeluxePaintIII or other Amiga programs. Anim tracks (like other Viewport tracks) are only allowed in Scene Scripts. ANIMBRUSH TRACK Controls animated brushes created with DeluxePaint III. These AnimBrushes can be played and moved about the screen. When you create an AnimBrush track, the Parts requester appears. Find the AnimBrush you want in the On Disk window, click it, and then click Select. See Parts Menu, below for more information about the Parts requester. Because no Object track can be displayed unless it is attached to a Viewport track, an AnimBrush track is automatically attached to the Viewport (Anim, Backdrop, or Picture) track immediately above it when you bring it into the Scene Script. Later you can attach the Animbrush track to some other Viewport track, if you wish. BACKDROP TRACK A Backdrop track is created on the fly by DeluxeVideo III instead of being read in from disk. A Backdrop has the same color palette as the equivalent screen in DeluxePaint. Backdrop tracks (like other Viewport tracks) are only allowed in Scene Scripts. The Special Effects video on the DVExamples1 disk is a good example of how to use Backdrop tracks. See Chapter 5, Video Effects, for more information. When you create a Backdrop track, the Backdrop requester appears. Modes This area determines the resolution mode of the Backdrop. Click the check boxes to activate the option (the check box is highlighted to show the active option). These modes correspond to the basic Amiga resolutions. Illegal combinations of modes are prevented. LoRes is 320 x 200 by 32 colors, HiRes is 640 x 200 by 16 colors, and Lace doubles the vertical resolution of either of these modes. HAM is Hold-And-Modify mode where all 4096 colors can be displayed at once, which can also have double vertical resolution with Lace. Xtrahb (Extra HalfBrite) is 320 x 200 (or 320 x 400 with Lace) by 64 colors. Size This area lets you set the size and depth of the backdrop. The width and height may be set up to 1008 x 800 pixels. The depth controls the number of colors available; click on the up or down arrows. Click the Use brush palette button so that the Backdrop takes on the color palette of any brush that is made visible. If several brushes are shown on a Backdrop, the palette changes with each new brush. Origin This area sets the origin point for the raster (see Appendix A). BACKGROUND TRACK One Background track is available in the Scene Script, only after you chose Expert from the Options menu. See the description of the Background track and its effect under Background Track in the section Tracks and Effects in the Video Script, above. BOX TRACK Use this track to control any object you create for your video while the video is playing. A box is a rectangular brush of a solid color with an outline and an optional shadow. Boxes are useful for surrounding text or setting off AnimBrushes or Brushes without creating more Parts. Because no Object track can be displayed unless it is attached to a Viewport track, a Box track is automatically attached to the Viewport (Anim, Backdrop, or Picture) track immediately above it when you bring it into the Scene Script. Later you can attach the Box track to some other Viewport track, if you wish. Size Click the up or down arrows to alter (in pixels) the Width and Height of the box. You can click directly on the numbers and type in a new value. Colors Click on the up or down arrows to select a color from 0 to 31. You can also click i the individual box and type the color number directly. This area controls the Body color, the Outline Color, and the Shadow. Click the Preview button to display the Box. As you change the colors the Box reflects your choices. Style Click Default Palette to use DeluxePaint's default palette. If you don't click Default Palette, the palette of the attached track is used. Click the Shadow checkbox to put a shadow on the Box; use the up and down arrows to change the amount of offset (in pixels) for the shadow. The offsets are limited to plus or minus 64 pixels. Click OK to accept the changes; click Preview to see what the Box looks like before accepting changes; or click Cancel to return to the Scene Script without placing a Box track. BRUSH TRACK Controls a DeluxePaint brush (or a brush from other graphics programs that allow you to save a brush. The number of brushes tracks that can appear in a Scene Script is unlimited. When you create a Brush track, the Parts requester appears. Find the brush you want in the On Disk window, click it, and then click Select. See Parts Menu, below for more information about the Parts requester. Because no Object track can be displayed unless it is attached to a Viewport track, a Brush track is automatically attached to the Viewport (Anim, Backdrop, or Picture) track immediately above it when you bring it into the Scene Script. Later you can attach the Brush track to some other Viewport track, if you wish. CONTROL TRACK One Control track is available in the Scene Script. See the description of the Control track and its effects (Button, GoTo, Label, KeyTo, Label, PanelOn, Pointer, TimeStep, and Wait) under Control Track in Tracks and Effects in the Video Script, above. DEVICE TRACK The Device track is available in the Scene Script, after you chose Expert from the Options menu. See the description of the Device track and its effect (Message) under Device Track in the section Tracks and Effects in the Video Script, above. PICTURE TRACK This is the most basic Viewport track. It displays an Amiga IFF image in any resolution. Anim tracks (like other Viewport tracks) are only allowed in Scene Scripts. SOUND TRACK The Sound track is used for playing an 8SVX file in a scene. When you create a Sound track, the Parts requester appears. Find the sound you want in the On Disk window, click it, and then click Select. See Parts requester below, under Parts Menu for more information. TEXTLINE TRACK This track gives you an easy way to bring text into a video. When you add a Textline track, the font image is drawn into a memory buffer and then copied into your video file. When the video is played, the image is read from disk and displayed. So, once added to the video you no longer need the font. If you change the text, how ever, you'll need the font again to generate a new image. Because on Object track can be displayed unless it is attached to a Viewport track, a Textline track is automatically attached to the Viewport (Anim, Backdrop, or Picture) track immediately above it when you bring it into the Scene Script. Later you can attach the Textline track to some other Viewport track, if you wish. When you create a Textline track, the Text Line requester appears. Text Click in this window and type the text you want to display. Always press Return after changing the text. Font Select the font you want by clicking it in the Font window. Click the arrows above and below the window's scroll bar or drag the slider to scroll the list of fonts. Drawer Click in this window and type in a different path to use fonts stored in a drawer other than your workbench. The original drawer is equivalent to sys:fonts. Colors Choose the primary and secondary colors for the text line (left box - primary) and its shadow (right box - secondary) by clicking the up or down arrows next to the color numbers. The color number 0 to 31. Style Click on the box you want to set the style attributes of the text line. Any or all of these styles may be chosen simultaneously. Click Default Palette to use DeluxePaint's default palette. If you don't click Default Palette, the palette of the attached track is used. If you select the (drop) Shadow style, you may want to use the up and down arrows to adjust the offset of the shadow image. The box on the left controls vertical offset; that on the right controls horizontal offset. The default offset is 1 x 1 pixels. You can also use this requester to choose from three color modes. JAM2 uses the primary color for the text and fills the box surrounding the text with the secondary color (rightmost box beside Colors). COMP complements, that is, reverses the bit pattern) the area in the video screen where the text appears. INV creates transparent text surrounded by the primary color. If both INV and JAM2 are selected, the primary and secondary colors are switched, which display the text in the secondary color surrounded by the primary color. Preview Click the Preview button to see the text line as you enter it or make changes to it. * Deluxe Video III supports color fonts, but you must run your color font utility before you use them in this program. EFFECTS Each track in the Scene Script has a corresponding effect or set of effects that you can use to refine your videos. The following is a description of all the types of effects that are used in Deluxe Video III, together with notation showing the corresponding track or tracks, and whether the effect uses a requester. * Some Scene Script effects are designed for expert users. They are only available after you've chosen Expert from the Options menu. If you want to add an effect to a given track, but can't find it in the Choose an Effect requester, choose Expert and display the Choose an Effect requester again. For example, if you have a Picture track to which you want to add a Back effect, you won't find Back in the Choose an Effect requester unless you have already chosen Expert from the Options menu. For purposes of the Picture track, Back is an Expert effect. BACK Tracks: Anim, Backdrop, Picture Requester: No Pushes the Viewport to the back of the viewport list. Usually, this effect is used to hide the current Viewport under another Viewport. You can use Back and Front (below) effects to flip between two pictures. BUTTON Track:Control See Button under Control Effects in Tracks and Effects in the Video Script above. CLEAR Tracks: Anim, Backdrop, Picture Requester:No Clears a viewport to color 0. CLRCYCL Tracks: Anim, Backdrop, Picture Requester:No Turns on whatever color cycling information is defined in the Part's data file. Color cycling creates an appearance of animation by changing the color palette of the image. The color cycles must be set from within the paint program that created the Part. CONTINUE Tracks:Backdrop Requester:No Operates only on the Back Drop track, causing the BackDrop to adopt the dimensions and view mode of the Viewport at the top of the Viewport list. The Continue effect lets you use the front viewport (Backdrop) from the previous scene to begin the next scene. The Continue effect must occur at the beginning of the scene. Follow it immediately with an Options effect (select Double Buffer from the requester) if you plan to move objects. See Special Effects in Chapter 5, Video Effects for an example of Continue. FADEIN Tracks: Anim,Backdrop,Picture Requester:No This effect causes the Viewport Part to gradually appear over the duration of the effect. The Viewport's colors are initially all set to color 0, the Viewport is made visible, then the color values are gradually increased until the Viewport is displayed normally. FADEOUT Tracks:Anim,Backdrop,Picture Requester:No This effect causes the Viewport to gradually disappear over the duration of the effect. The Viewport's colors are gradually reduced in value until they are all set to color 0, then a Hide effect is automatically performed at the end of the FadeOut. FADEPTRN Tracks: Anim, Backdrop,Picture Requester:No This effect causes the Viewport Part to change color (under the influence of a concurrent Pattern effect), so it matches the palette of a viewport track, which is attached to it. FRONT Tracks: Anim, Backdrop, Picture Requester:No This effect pushes the Viewport to the top of the display list. Typically, this is used to bring a Viewport into view after begin obscured by other Viewports. GOTO Tracks: AnimBrush, Box, Brush, Control, Textline Requester:Yes You may want to look at GoTo that appears under Control Effects in Tracks and Effects in the Video Script above. We're repeating part of that description here because GoTo Works differently as a Screne Script effect. On an Object track (AnimBrush, Brush, or Textline) in a Scene Script, it works in conjunction with a Wait effect. If you click the mouse on the object while waiting, then it will GoTo the label indicated in the Object's GoTo effect. See the description of the MultiMedia sample video in Chapter 5, Video Effects for more information. Video If this is on, the name is interpreted as the name of a video. If it's off, the name is interpreted as the name of a scene. Name Click here and type in the name of the scene you want to go to. The path name isn't required if the scene is in the same drawer as the video currently running. HAMFIXUP Tracks: Anim, Backdrop, Picture Requester:No This effect cleans up the fringing effect on a HAM mode picture or brush as it is moving. Note that this process slows down the frame rate of the video considerably. We recommand this feature primarily for single frame recording of a video and for creating an anim with the MakeAnim effect. HIDE Tracks: Anim, AnimBrush, Backdrop, Box, Brush, Picture, Textline Requester:No Marks the Object as invisible and removes it from view. This effect is the reverse of Show. The Background track also supports a Hide effect. See Background Track under Video Script in Reference, above. JOYSTICK Track: Control See Joystick under Control Effects in Tracks and Effects in the Video Script above. KEYTO Track:Control See KeyTo under Control Effects in Tracks and Effects in the Video Script above. LABEL Track:Control See Label under Control Effects in Tracks and Effects in the Video Script above. LOAD Tracks:Anim, AnimBrush, Box, Brush, Picture, Sound, Textline Requester:Yes Opens the selected Part file and preloads it into memory, so there's no delay for file loading when you want to play or display that Part. Use a Load effect before an effect that plays Play (Sound for example) or displays the selected Part. This makes the video run more smoothly because there'll be no pause while the part loads. In an Anim track, Load let's you control disk I/O so that animation is not interrupted. LOCKCLRS Tracks: Anim, Backdrop, Picture Requester:No This effect prevents the Viewport's color palette from being changed when a brush is made visible. The brush is then forced into the palette of the Viewport. MAKEANIM Tracks: Anim, Backdrop, Picture Requester:Yes This effect is used to create Anim files from videos. While the video plays, Anim frames are recorded, compressed, and written to disk. When you create this effect, the MakeAnim requester appears. Click in the Name window and type the name of the Anim file you want to create. You can also specify the path in this edit field. If no path is specified, DVMaker saves the file to the current path. The Maximum File Size option lets you restrict the size of your anim and thus avoid creating unusually large (and memory intensive) anims. The size of the Viewport cannot change during a MakeAnim effect. While the Anim is recording, the current frame number is shown in the mouse pointer. Two extra frames are added to the end of the Anim so that it can be cycled. Use the TurnOn and TurnOff options in the Edit menu to control when an Anim is actually made. Once you place the MakeAnim effect, immediately select it and select Turn Off from the Edit menu. Now while you continue to setup your video and adjust it, you won't be making as tring of Anim Files. When you have the video exactly the way you want it, Turn On the MakeAnim effect and then play the video to make the Anim. See the description of the MakeAnim example in Chapter 5, Video Effects for more information. MESSAGE Track:Device See Message under Control Effects in the Control Track section above. MOVEPATH Tracks: AnimBrush, Box, Brush, Textline Requester:Yes Tells the Object to follow a path relative to the origin of the track it's attached to. When you create this effect, the MovePath requester appears. Points Lists the x and y coordinates of each point in the path of the Object. To select a particular point, click on it in the list. When you select a point, its coordinates appear in X and Y boxes. You can change these coordinate by clicking the up or down arrows, or by clicking in the box, typing a new value, and then pressing Return. You must press Return for the new numbers to be entered. Click Change to enter the new values of the selected point. Click Insert to add a new point to the list after the curretnly selected point. The new point's coordinates are (x+10,y+10) where x and y are the coordinates of the selected point. If no point in the list is selected, the new point is added after the first point. The new point is automatically selected. Click Delete to remove the currently selected point from the list. This automatically selects the previous point on the list. Options Click the appropriate check boxes to choose the options you want (the check box is highlighted when the option is active). Repeat means that you Object follows the selected path the specified number of times. Change the number of repeats by clicking the up or down arrows or by clicking in the window and typeing a new number. Continuous means that your Object follows the selected path for the duration of the effect. Absolute means that the coordinates are measured from the origin of the track to which the object is attached. Relative means that the corrdinates are measured from the position of the Object at the start of the effect. Normally you'll want to use a Position effect before your MovePath effect if you use this option. Cycle means that the points are followed in the order 1, 2,...N,1,2,...N. PingPong means the points are followed in the order 1,2, ...N, N-1, ...2,1. TimeStep is the number of jiffies (1/60th of a second) between data points. As you trace the path, the points are recorded according to the Time Step entered here. As the video plays, the Object's position is linearly interpolated between the data points (a process also known as tweening). Use a small value if you want to drag the Object quickly and a larger value if you want to drag it slowly. Loop Point defines the point to use after point N when cycling through the path; this lets you repeat only part of the path rather than the entire path. Change the loop point by clicking the up or down arrows or by clicking in the window and typing a new value. Show At Start automatically does a Show effect before the MovePath effect starts. Hide At End automatically does a Hide effect at the end of the MovePath effect. Trace Trace is usually the first thing to do when you create a MovePath effect. Click this button to display the Preview screen. Drag the Object to the starting position of the path you want, and release the button (you may need to press h to reduce the picture to half size so you can position the object off-screen; see the discussion of Preview in the Parts requester under Parts Menu, below for more details and a listing of keyboard equivalent commands). When you press the mouse button down on the object again, the old path is erased and a new path is created. Drag the object along the path you want and release the button. When you're finished tracing the path, press Esc to switch back to the Path requester or press j to jumpt to the Edit screen. TIP: Use Trace to define the path and Edit to redefine it. Don't edit the poitns unless you require a precise path. Edit After you've traced a path, this screen lets you edit the points on that path. Click Edit to bring up the Edit Preview Screen (see the discussion of Preview in the Parts requester under Parts Menu, below for more details and a listing of keyboard equivalent commands). A series of straight lines defines the Object path; small square outlines frame each point. The object itself is drawn at the currently selected point. Six sizing boxes appear around the perimeter of the path. * Extra Preview keys are active while you're in Edit or Trace. The + key selects the next point and draws the Object there; the - key selects the previous point and draws the Object there .a shows all other Parts attached to the same track. i inserts a new point (just like the Insert button in the Path requester); d deletes the current point (just like the Delete button in the Path requester). To edit a specific point, press + or - to move the Object to that point and then drag the Object with the mouse. To move the entire path, press down the mouse button on the empty space within the path's bounds and drag the path where you want it. You can stretch or compress the path by dragging the appropriate sizing box on the path perimeter. MOVETO Tracks: Anim, AnimBrush, Backdrop, Box, Brush, Picture, Textline Requester:Yes This effect specifies what part of an Object to display and where to display it, relative to the Object it's attached to. You can move an Object to a specific point while you alter the amount of the object you reveal. You can specify what and where by entering values into the What and Where requester or by directly manipulating the Object on a Preview Screen. See the description of the What & Where example video in Chapter 5, Video Effects, for more information. What Controls what portion of the Objects to display. If the Full Width and Full Height check boxes are active, the rest of the controls are unavailable. The first box controls the number of pixels. The second box controls the amount of pixels from the left, right, center or origin of the Object, depending on the check box you chose. Change the values by clicking the up or down arrows or by clicking in the window and typing a new value. When the Max Height or Max Width gadgets are deselected, the Part's actual height and width appear (rather than the default 1024). Where Controls where the Object moves to on the screen. The first box controls the number of vertical pixels from the left, right, center, or origin of the Object, depending on the check box you choose. The second box controls the same conditions for horizontal pixels. Click the up or down arrows to change the values or click in the window and type a new value. Show at Start automatically shows a Show effect before the MovePath effect starts. If Show at Start is not on, the Part is loaded and prepared for showing. Hide At End automatically does a Hide effect at the end of the MoveTo Effect. You can use these options rather than adding effects (that do the same job) on the track. Preview What Displays the Preview What screen. The Object appears against a blank Backdrop. A rectangle is drawn around the Object, with tabs at the corners and the midpoints of each side. Change the size of the rectangle by dragging the tabs. Move the Object by dragging the interior of the rectangle. The changes are reflected in the What and Where requester. Press j to toggle between the Preview What and the Preview Where screens. Preview Where Displays the Preview Where screen. The Object is shown against the Viewport to which it's attached at the point where it will be displayed when the video plays. A rectangle is drawn around the Object. Move the Object by dragging the interior of the rectangle. The changes are reflected in the What and Where requester. OPTIONS Tracks: Anim, Backdrop, Picture Requester:Yes This effect lets you change the display options for the Viewport track. See Special Effects in Chapter 5, Video Effects, for more information about this effect and examples of how to use it. When you create this effect, the Display Options requester appears. Double Buffer When this option is active, two copies of each rastport (that is, two buffers) are allocated in Chip RAM. Brushes are animated by drawing in one buffer while displaying the other buffer, and then flipping between the two when the drawing is completed. This option must be on for flicker-free brush animation. However, Double Buffer doubles the amount of Chip memory needed for each raster, so if you're just showing slides, don't use Double Buffer. Restore Black When a brush is moved over a raster, this option restores the raster with color 0 using the mask of the brush. If you are doing brush animation over a color 0 backdrop, you can get faster and smoother animtion by selecting this option. Save & Restore When this option is active, Deluxe Video III saves what is under the raster as a brush moves over it, and later restores what was there. Double buffering with save & restore is the classic form of brush animation. Restore Pattern The attached pattern is used to restore the background. This option makes it possible to drag a brush across one picture and reveal another picture in the process. Don't Restore As an Object moves over the Viewport its image is left in the background, leaving a history of where it has been. PAN Track:Sound Requester:No You can add a Pan effect to a Sound track to change the position of a sound while it's playing. Pan must be preceded by a Play (Sound) effect with the Stereo option on, so the sound can pan between the left and right channels. PANELON Track:Control See PanelOn under Control Effects in Tracks and Effects in the Video Script above. PATTERN Tracks:Box, Brush,Picture,Textline Requester:Yes You can add a Pattern effect to any Picture or Brush track that's attached to a Viewport track (an Anim,Backdrop, or Picture track), after you've selected Expert from the Options menu. This effect makes the selected Part the pattern for the Picture or Brush it's attached to. That track then becomes a pattern for the Viewport for the duration of the Pattern effect. The pattern doesn't have to be the same dimensions as the Viewport. If it isn't the same size, you can set the options so the Viewport is tiled with the pattern. The Pattern effect doesn't draw or cause anything to be drawn in the Viewport. To do that you must use a WipeIn effect or an Options effect after setting the Restore Pattern flag. See Wipes & Pattern and Special Effects in Chapter 5, Video Effects, for examples of how to use the Pattern effect. DON'T TILE The pattern's center is located at the viewport's center. Any area beyond the edge of the pattern is drawn in color 0. VERTICAL TILES The pattern's center is located at the viewport's center and is repeated vertically until the viewport is covered. The same vertical band is repeated to the right after shifting down by the tile offset, and it is repeated to the left after shifting up by the tile offset. HORIZONTAL TILES The pattern's center is located at the viewport's center and is repeated horizontally until the viewport is covered. The same vertical band is repeated below after shifting right by the tile offset, and it is repeated above after shifting left by the tile offset. TILE OFFSET The number of pixels to shift for vertical or horizontal tiles. Adjust by clicking the up or down arrows. PICKUP Tracks:Box, Brush, Textline Requester:No Replaces the Object's image with what is under it in the Viewport at the time of the effect. The result is like a cookie cut of the underlying background. See special Effects in Chapter 5, Video Effects for an example of Pickup. PLAY Track:Sound Requester:Yes Plays a selected Sound track. When you creat this effect, the PlaySound requester appears, where you can adjust how the Sound plays. Adjust any of the sliders by clicking on the arrows to the left and right of the slider or by dragging the bar in the slider to the position you want. Frequency If this box is selected, the Sound plays at the sample rate shown at the right. The frequency ranges from 100 Hz to 30K Hz. Position If this is selected, the sound plays at the stereo position indicated. 0 indicates the left stereo channel and 319 is the right stereo channel. A value between 0 and 319 is a proportional stereo position. Note that any value other than 0 or 319 uses two of the four available audio channels, rather one channel. Volume If this box is selected, the volume value at the right is used (from 0 to 127). If the box is not selected, the sound plays at full volume. Repeat If this is selected, the Sound plays repeatedly the indicated number of times. Continuous If this box is selected, the Sound repeats for the duration of the effect. Priority This indicates the relative priority of the current Sound. There are four audio channels on your computer, two left and two right. When a Sound is played, it's assigned to the channel indicated by the Position setting in the Play effect. If there is a channel, it will play. If there isn't a channel available, another Instrument track or Sound of lower priority will be temporarily bumped until the current Sound is completed. The bumped Sound will resume when it can. Stereo Click to produce stereo sound. Preview Click to hear the Sound and test your settings. Click again to stop the Sound. PLAY ANIM Tracks:Anim, AnimBrush Requester:Yes This effect applies only to the Anim and AnimBrush tracks. It controls how an Anim or AnimBrush plays during the video. The Play Anim effect makes the Anim Brush visible if it hasn't yet had a Show effect. When you create a Play Anim effect, the Play Anim requester appears. ANIMS Click the appropriate box to choose an available option (the box is highlighted when the option is active). Change the values by clicking the up or down arrows or by clicking in the window and typing a new value. Cycle Anima are normally designed to cycle from their first frame through a sequence ending at the first frame; if this option is selected, that's how the Anim is played. If this option is turned off, the AnimBrush plays once from the first frame to the last frame. * Ping Pong, First Frame, Last Frame, Next Frame, Previous Frame, Frame, Start Frame, and End Frame are not available for Anims. Continuous Plays for the duration of the effect. You may change the duration by dragging the effect's End arrow. Repeat Plays for the indicated number of repetitions. The duration is computed so you may not change it. Repetitions This value shows the number of times to repeat the Anim playing. Loop Frame This sets the frame number when the Anim repeats. Time Interval This sets the time interval between frames. The default setting here is the setting made in the Video track; you can override the default for this effect. ANIMBRUSHES Click these check boxes to choose these options (the check box is highlighted when the option is active). Change the values by clicking the up or down arrows or by clicking in the window and typing a new value. Forward Plays the AnimBrush from the first frame through a sequencye ending at the last frame. Ping Pone Plays the AnimBrush from first frame to last frame, then backwards from last frame to first frame. First Frame Jumps the AnimBrush to frame 1. The duration is automatically set to zero. Last Frame Jumps the AnimBrush to frame n. The duration is automatically set to zero. Next Frame Jumps the AnimBrush to the next frame. The duration is automatically set to zero. Previous Frame Jumps the AnimBrush to the previsou frame. The duration is automatically set to zero. Frame Jumps the AnimBrush to a specific frame. The duration is automatically set to zero. Continuous Plays for the duration of the effect. You may change the duration by dragging the effect's End arrow. Repeat Plays for the indicated number of repetitions. The duration is computed so you may not change it. Repetitions Shows the number of times to repeat the AnimBrush playing. Start Frame Sets the start frame for the AnimBrush. End Frame Sets the ending frame for the AnimBrush. Time Interval Sets (in jiffies) the time interval between frames. The default setting here is the setting made in the Video track; you can override the default for this effect. If you're using simultaneous PlayAnim effects, you should have the same time interval in each one. * Loop Frame is not available for AnimBrushes. POINTER Track:Control See Pointer under Control Effects in Tracks and Effects in the Video Script above. POSITION Tracks: Anim, AnimBrush, Backdrop, Box, Brush, Picture, Textline Requester: Yes This effect operates like a MoveTo effect except that there is no duration. Position specifies what part of an Object to display, and where relative to the Object it's attached to. Objects can be displayed at a specific point with a specific amount of the object being revealed. You can specify what and where by entering values into the What and Where requester or by directly manipulating the Object on a Preview Screen. What - This area controls what portion of the Object to display. Where - This area controls where the Object is displayed on the screen. * See the detailed description of the What and Where requester under MoveTo, above for more information. RELEASE Tracks: Anim, AnimBrush, Backdrop, Box, Brush, Picture, Textline Requester: No Automatically does a Hide effect on the Object, which changes its state from prepared to loaded. This frees up some memory for other Parts of the video to use, but doesn't unload the Object. SCROLL Tracks: Anim, Backdrop, Box, Brush, Picture, Textline Requester: Yes This effect lets you adjust the view of the selected Object. See Scrolling BG in Chapter 5, Video Effects, for an example. When you create this effect, the Scroll requester appears. Change the values by clicking the up or down arrows or by clicking in the window and typing a new value. X: This is the number of pixels to scroll horizontally; a positive number indicates right while a negative number indicates left. Y: This is the number of pixels to scroll vertically; a positive number indicates down while a negative nubmer indicates up. T: This is the period of time (in jiffies) to scroll the indicated x-y distance. SHOW Tracks:Anim, AnimBrush, Backdrop, Box, Brush, Picture, Textline. Requester: No This effect makes the Object visible at its current position if no previous effect has yet made it visible. If you haven't loaded an Object into the video, a Load effect is automatically preformed. If you haven't positioned an Object in the video, a Position effect is automatically performed using the default center position. This effect is ignored if the Object is already visible. SLIDEIN Tracks: Anim, Backdrop, Picture Requester: Yes This effect gradually brings a Viewport into view. When you create a SlideIn effect, the Slide In requester appears. Four patterns are displayed in the requester, the selected pattern is highlighted. Click on the pattern you want to use. Click Slide to make the Viewport slide into view; click Reveal to have the Viewport gradually revealed. The two patterns on the right of the requester look best with Reveal selected. SLIDEOUT Tracks: Anim, Backdrop, Picture Requester: Yes This effect gradually moves a Viewport out of sight, ending with an automatic Hide effect. When you create a SlideOut effect, the Slide Out requester appears. Four patterns are displayed in the requester; the selected pattern is highlighted. Click on the pattern you want to use. Click Slide to make the Viewport slide out of view; click Reveal to have the Viewport gradually concealed. The two patterns on the right of the requester look best with Reveal selected. STAMP Tracks: AnimBrush, Box, Brush, Textline Requester: No This effect works on a brush track to copy the brush image permanently to the Viewport. Leave this effect on while the brush is moving to create a trail of images. TIMESTEP Track: Control See TimeStep under Control Effects in Tracks and Effects in the Video Script above. UNLOAD Tracks: Anim, AnimBrush, Box, Brush, Picture, Sound, Textline Requester: No This effect erases a selected Object, Viewport, or Part from memory and frees up more room in the video. If the video has many Parts or scenes, it's a good idea to Unload those that are not currently in use. UNSCROLL Tracks: AnimBrush, Box, Brush, Textline Requester: No This effect can be added to any Object track. Use this effect if the brush is in front of a scrolling backdrop and you want the brush movement to be relative to the screen rather than the scrolling background behind the brush. See Scrolling BG in Chapter 5, Video Effects, for an example. USECLRS Tracks: AnimBrush, Box, Brush, Textline Requester: No This effect copies the brush palette to the Viewport where the brush is attached. UseClrs is an Expert effect, which can only be used on Object tracks. WAIT Track: Control See Wait under Control Effect in Tracks and Effects in the Video Script above. WIPEIN Tracks: Anim, AnimBrush, Backdrop, Box, Brush, Picture, Textline Requester: Yes This effect brings up the Wipe effect requester where you specify how a new viewport or brush is wiped into the existing viewport. When a scene is started with a WipeIn effect on a viewport track, the wipe is done from the old image to the new image if the old image from the previous scene is the same height, width, and depth as the new images. Otherwise, the viewport is cleared to color 0 and the image is wiped in. The new color fades in at the same time as the image. If another track with a Pattern effect is attached, the pattern is wiped in. WIPE DIRECTION ICONS There are thirteen icons at the top of the Wipe effect requester representing different directions for the new image to wipe in. the bottom two icons are for two special patterns that are more like dissolves than true wipes. The left icon is a random line by line dissolve (regradless of the type selected), and the right icon is a random pixel by pixel dissolve (or random check dissovle if check or diamonds is selected). Click on the desired Wipe Direction icon to select it. * If you add a new wipe to a track without selecting a direction, the direction is chosen randomly at play time. TYPE There are four choices for the type of Wipe; click on the check box to select the desired type. Tiny is a 16 pixel wide pattern-based wipe. Solid is a full-sized solid pattern wipe. Checks is a checkerboard wipe with each check set to the width and height specified in the bottom left portion of the requester. Diamonds is a singel or multipled diamond wipe with the number of horizontal and vertical diamonds indicated in the lower right corner of the requester. * If you add a new wipe to a track without selecting a type, the type is chosen randomly at play time. CHECKS WIDTH AND HEIGHT Enter the width and height for the checks by clicking on the up or down arrows, or by typing directly in the boxes. These are equivalent LoRes sizes; if the viewport is HiRes the actual pixel width is twice this value (likewise for the hight in lace mode). When played, if the width and height specified would require more than 1024 checks for the image being wiped, both width and height are doubled until the wipe requres less than 1024 checks. DIAMONDS HORIZONTAL AND VERTICAL Enter the number of diamonds to use for horizontal wipes and for vertical wipes by clicking on the up or down arrows, or by typing directly in the boxes. When played, if the values entered would produce a diamond less than 8 pixels high or wide, the values are increased until the diamond is at least that large. WIPEOUT Tracks: Anim, AnimBrush, Backdrop, Box, Brush, Picture, Textline Requester: Yes This effect is similar to WipeIn, except that it is used to remove an image from view and it does not use attached patterns. See WipeIn for details. CONTROL PANEL You can control a video while it's playing (through DVMaker or DVPlayer) by using the Control Panel or the keyboard. To display the Control Panel, while the video is playing: > Press the Help key or the right mouse button. Pressing either Help or the right mouse button removes the Control Panel when the Control Panel is visible. The Control Panel normally appears at the bottom of the view, but if the view is overscan, the Control Panel is shown in the normal (non-overscan) region so that it's totally visible. See Control Panel, below for a complete descrition of all the buttons and functions of the Control Panel.
