Use the revVideoGrabDialog command to specify settings for use with the video grabber.

Parameters:

The settingsType is one of the following:

compression: Settings for compression when recording video

format: Video format, dimensions, and image depth

display: Appearance of previewed video in the video grabber

source: Video input channels and hue, contrast, and saturation settings

Note: Some video camera drivers don't support some settingsTypes.

Comments:

You must use the revInitializeVideoGrabber command to open the video grabber before you can use the revVideoGrabDialog command.

If you specified "QT" as the video method when you executed the revInitializeVideoGrabber command, do not specify a settingsType. QuickTime video recording settings are found in a single dialog box, which you display with the following statement:

revVideoGrabDialog

If you specified "VFW", use the settingsType parameter to specify which dialog box you want to show.

Important! The revVideoGrabDialogcommand is part of the Video library. To ensure that the command works in a standalone application, you must include this custom library when you create your standalone. In the Inclusions section on the General screen of the Standalone Application Settings window, make sure that "Video Grabber" is selected from the list of script libraries.

You use revVideoGrabDialog in conjunction with revVideoGrabSettings and revSetVideoGrabSettings. Here is a sample handler for choosing, saving and setting the video grabber settings:


on mouseUp
revVideoGrabDialog
local vSettings --docs say the variable has to exist before referring to it
revVideoGrabSettings "vSettings"
set the videoSettings of this cd to vSettings
revSetVideoGrabSettings "vSettings"
end mouseUp

Two additional setting types were added to 2.9 as noted by Mark Waddingham in bug 5897 http://quality.runrev.com/qacenter/show_bug.cgi?id=5897
His comment is quoted below
For the next build of 2.9 I have done the following:
1) Added two new keywords to 'revVideoGrabDialog': - 'audio' pops up the QT audio compression choice dialog for the videograbber - 'video' pops up the QT video compression choice dialog for the videograbber
so


revvideograbdialg "audio"


will show the QT audio compression dialog.
