videograbber sound encoding preferences

[Richard Miller]

Trevor,

I am currently working with the video functions under XP. Can't say  
for sure what works under OSX. This does work under XP (using the  
latest Rev Windows file, revVideGrabber.dll).

RevSetVideoGrabCompressor "Morgan MJPEG Compressor"
RevSetVideoFrameRate "30"
RevSetVideoGrabAudio true, "1","8","11025"
revRecordVideo movfile

This series of commands (which uses the Morgan codec) gives me very  
high-quality compressed video (under 1000 kbits/second frame rate, 30  
frames per second). When I check the resulting .avi file in Apple's  
Quicktime Player and go to MOVIE INFO, it shows "8-bit Unsigned  
Integer, Mono, 11.025 kHz".

Sorry it took so long to get back to you. Been traveling.
