#$VER: VLabHelp 1.3 (15.4.92) This file contains a short description on each menu-item of VLab. In spite of that fact, please read the documentation carefully, because there the functions are explained in detail. #ABOUT This Requester gives some information about the program. (Things like current version-number, name of the arexx-port and name of the VLab-Public-Screen. #AUTODISPLAY If active, the Amiga-picture will be displayed after it has been converted. #AUTOPREVIEW If active, the YUV-picture will be displayed as preview after it has been changed, e.g. after loading a picture or snapping a new picture. #AUTOSAVEENV If active, the settings will be saved automatically after your VLab-session is terminated. The settings will be automatically re-loaded at any time you start a new session. #AUTOUNDO If active, the YUV-picture in memory will be buffered when it is going to be changed. With 'Get back picture (Undo)', you can get back the previous picture. #AUTOUSEENV If active, the settings of VLab will be saved for your next restart. The settings will not survive a reset, it is only temporarily. #BLACKBACKGROUND If active, the background-color will be black after converting a YUV-picture into an Amiga-picture. #CLEAR ALL All internal buffers will be cleared. #CLEAR UNDO The additional buffer will be cleared. #CLOSEWINDOW The currently active window will be closed. #CONVERT The YUV-picture will be converted into an Amiga-IFF-picture of the previously chosen type. This procedure can take several seconds or even minutes, depending on the speed of your computer. #CONVERTMODE This command sets the picture type, that will be used for the YUV-Amiga-conversion. If 'Hires' is aktive, the YUV-picture will be converted into a Hires-Amiga-picture, otherwise it will be scaled to Lores. #CONVERTMODE BW If active, the YUV-picture will be converted into a B/W-picture. #CONVERTMODE COLOR If active, the YUV-picture will be converted into a color-picture. #CONVERTMODE HAM If active, the YUV-picture will be converted into a HAM-picture. #COPYTOUNDO The current YUV-picture is going to be copied into a second buffer and can be get back with 'Get back picture (Undo)'. #DEINTERLACE With this option, unsharp effects caused by movements within a fullframe picture will be removed by calculations. This makes it possible to avoid these effects without loosing the higher resolution of a full frame. #DELETEFILE After opening a file requester, a file can be deleted completly with its eventually existing icon. #DELETEMACRO The Execute-requester will be opened and you can enter the name of the macro you want to remove from the VLab-macro-list. The macro will not be deleted on disk. #DISPLAY A previously converted Amiga-picture will be displayed. #DITHER If active, the Floyd-Steinberg-dithering-algorythm will be used while converting a YUV-picture. This makes it possible to get good pictures even if you have only a few grey levels or colors. Converting a color-picture this funktion takes quite a long time. #ERASEPREVIEW The Window containing a preview-picture will be cleared. #EXPORT24 The current YUV-picture will be converted into an RGB-24-bit-picture and saved as IFF-file. This should be operable with all common Amiga-videoprocessing-software. It is not recommended to use it for YUV-picture-saving because the procedure takes quiete a long time and the file will be very long. #EXPORTAMIGA The previously converted Amiga-IFF-picture will be saved in IFF-form. #FONT You can load a window-font of your choice. VLab works fine even with proportional fonts. The layout of all windows will be changed automatically. #FONT DEFAULT As current window-font VLab will use the 'System-default-font', which is also used by the Amiga-shell. #FONT TOPAZ 8 Current window-font will be 'topaz 8'. #FONT TOPAZ 11 Current window-font is 'topaz 11'. #FONT USER Current window-font is the previously defined 'Disk-font'. #HELP A requester informs you about the Menü-Help-option. #INPUT 1 If active, the CVBS-input No. 1 (the lower one) will be activated. #INPUT 2 If active, the CVBS-input No. 2 (the upper one) will be activated. #INPUT 3 If active, the CVBS-input No. 1 on a second VLab-hardware will be activated. #INPUT 4 If active, the CVBS-input No. 2 on a second VLab-hardware will be activated. #INPUT 5 If active, the CVBS-input No. 1 on a third VLab-hardware will be activated. #INPUT 6 If active, the CVBS-input No. 2 on a third VLab-hardware will be activated. #LOADMACRO A Macro will be selected and placed in the 'User' menu. As a Macro you may choose a VLab-Macro, an ARexx-script, a batch-file like the startup-sequence or even an executable Program. #LOADSETTINGS Previously saved custom-settings can be loaded and used immediately. #LOADSETTINGS DEFAULT All settings will be reset to an internal fixed standard-value. #LOADSETTINGS ENV:VLAB/VLAB.PREFS The last temporarily saved settings will be loaded and used. #LOADSETTINGS ENVARC:VLAB/VLAB.PREFS The last durable saved settings will be loaded and used. #MACRO Macros, defined by 'Load macro...' will be placed here. You can delete a Macro using the VLab-command 'DELETEMACRO Name'. #MONITOR The monitor-option can be activated and deactivated. #MONITORPRI The priority of the monitor-process can be toggled. If it is high, the monitor is refreshed during calculations. In this case the calculations are of course slower caused by the calculating time required by the monitor process. #MONITORSIZE If active, the monitorwindow will be resized to 200% . The refreshrate will decrease significantly caused by the four times higher amount of data. #OPEN A filerequester to open a YUV-picture will be opened. Besides the YUV-standard, you can also load the special VLab-pictures recorded by the VLab-sequence-recording. #OPENWINDOW COLOR The Colorcorrection-window will be opened. #OPENWINDOW COMMAND A window will be opened which allows the input of a VLab-ARexx-command. #OPENWINDOW CONVERT A window to convert an YUV-picture into an Amiga-picture will be opened. #OPENWINDOW DEFINESOURCE The Source-definition-window will be opened. #OPENWINDOW SCAN The Scan-window will be opened. #OPENWINDOW SEQUENCE The Sequence-window will be opened. #OPENWINDOW SELECTSOURCE The Source-selector will be opened. #PREVIEW A rapidly converted preview of the YUV-picture will be displayed. The quality is of course much lower than the results of the slower 'Convert'. #PREVIEWMODE The preview-mode can be chosen. With 'Scaled' aktive, the size of the picture will be reduced to fit the current window, this will last some extra seconds. 'Full frame' currently only works in conjunction with the Harlequin-card. 'Color' selects if the preview is calculated in color or in black-and-white. A preview in a window always is displayed in black-and-white. #PREVIEWOUTPUT WINDOW If active, the preview will be displayed in an own window on the VLab-screen. #PREVIEWOUTPUT BACKDROP If active, the preview will be displayed on the background of the VLab-screen. #PREVIEWOUTPUT SCREEN If active, the preview will be displayed on an own screen of the chosen size and resolution. #PREVIEWOUTPUT HARLEQUIN If active, the preview will be displayed over the Harlequin-Card in 24-bit-format. Because the quality is very high you really cannot call this a preview! #QUIT Termintates the current VLab-session. A safety-requester is displayed only if 'Safety requesters Many' is selected. #SAVE The current YUV-picture will be saved. You will get a warning if such a file already exists. #SAVEAS The YUV-picture will be saved, you will be asked for a file name previously. You will get a warning if such a file already exists. #SAVEICONS Automatically generates icons at saving pictures, macros or settings. For this function the VLab-Default-Icons have to be present in the directory 'ENV:VLab'. #SAVESETTINGS Saves custom settings. #SAVESETTINGS ENV:VLAB/VLAB.PREFS Temporarily saves settings -- they will not survive a reboot. #SAVESETTINGS ENVARC:VLAB/VLAB.PREFS Durably saves settings -- they will survive a reboot. #SAFETYLEVEL LOW When active, VLab is not going to display safety requesters and warnings. Only Errors will be highlighted. #SAFETYLEVEL MEDIUM If active, VLab will brings safety requesters and warnings only at important points. #SAFETYLEVEL HIGH If active, VLab will bring safety requesters at any small problem. #SCAN Digitizes a picture and copies it automatically into the YUV-buffer from which it can be displayed, converted or saved. #SCANMODE Here you can fix the way the picture should be stored into the YUV-buffer after it has been digitized. If 'Full frame' is active, VLab will read a full-frame-picture. You have to select 'Color' if you decide to scan color-pictures. If you did not select 'Hires' the picture will be converted to Lores immediately. #SCREENDEPTH 1 Sets the VLab-screen to only 2 grey levels. #SCREENDEPTH 2 Sets the VLab-screen to 4 grey levels. #SCREENDEPTH 3 Sets the VLab-screen to 8 grey levels. We recommend this mode for a good quality of the monitor-option. #SCREENDEPTH 4 Sets the VLab-screen to 16 grey levels. The speed of the Amiga will be reduced significantly by such a screen. The monitor-window may start flashing because blitter effects will occur. #SCREENFONT You can load a screen-font of your choice. VLab works fine even with proportional fonts. The layout of all menus will be changed automatically. #SCREENFONT DEFAULT As current screen-font VLab will use the 'System-default-font', which is also used by the Amiga-shell. #SCREENFONT TOPAZ 8 Current screen-font will be 'topaz 8'. #SCREENFONT TOPAZ 11 Current screen-font is 'topaz 11'. #SCREENFONT USER Current screen-font is the previously defined 'Disk-font'. #SCREENMODE WORKBENCH VLab will open all its windows on the Workbench-screen. For correct colors of 'Preview' and 'Monitor' please use the Palette-Presets in 'Prefs:Presets/VLab'. #SCREENMODE DEFAULT If active, VLab will perform on an own screen which is identical with the Workbench-screen in size and color depth. #SCREENMODE HIRES If active, VLab will perform on an own HiRes-Screen. #SCREENMODE HIRESLACE If active, VLab will perform on an own HiRes-Interlace-Screen. #SCREENMODE PRODUCTIVITY If active, VLab will perform on an own Productivity-Screen, if ECS is available and the Multiscan-monitor has been announced accordingly. #SEQUENCENAME Using a file-requester, the path and name of a sequence which should be grabbed can be entered. VLab will append a successive number to the name for each picture. #SEQUENCE CONTINUE You can continue a previously terminated sequence-recording. #SEQUENCE START The digitizing, importing and saving of a sequence will be started. #SEQUENCE STOP The digitizing, importing and saving of a sequence will be interrupted. #SEQUENCEMODE You can select the way in which the picture will be stored in the YUV-buffer. If 'Lace' is selected, you will get a fullframe picture, otherwise only one frame. To get a color-picture you have to select 'Color'. With 'Hires' active you will get a Hires-picture otherwise Lores. #SPECIALCONVERT If active, you can calculate pictures the Amiga can not display without additional hardware. You may transfer them to other computers. #UNDO You can get back the additional picture previously stored by 'Copy to Undo-buffer' or 'Auto-Undo' (Undo). #VLABRESET The VLab-hardware will be resetted. The Amiga will not be affected by such a reset. #VTRMODE This enables the 'Time-Base-Correction' of a video cassette recorder. This is required to grabb from running VCRs. An external TBC is not required for VLab at all. #WORKBENCH The Workbench can be closed or opened in order to control the available memory. #YUVTOLORES A Hires-YUV-picture will be converted to Lores.
