[jitter] Re: recording precise video lengths...

Fri Nov 2 10:19:11 MDT 2007

sorry i missed the follow up on this!
glad the patch worked out for you...mostly.
here's another way of doing it.  
I looked at qt.grab help file and was reminded that it has it's own recorder built in. Lesson learned - just when you think you know everything, you don't.
This will do audio and video.  The drawback to this method is that your live camera feed is kinda shot during recording, in spite of the supposed "write_preview" support.  You also have less control over audio, so clicks and pops at loop points may be prevalent, since you can't do a nice fade in/out at start/end as you could with the MSP audio.  
That said, this patch is HELLA FUN!
