What do you suggest using for compositing?

WinFF is probably the most well-known free option: http://winff.org

It does a number of both audio and video formats, I've used it in years past. My main concern is if WMM can do multiple audio channels well. I don't know how we're going to be laying that out quite yet.

I use Adobe products such as After Effects and Premiere, both can export .MOV format files. What I do is I render the animation and output as an image sequence then I import the sequence into After Effects and composite it there.

I use Adobe products such as After Effects and Premiere, both can export .MOV format files.

I tried to use Adobe Premiere but the quick time presets are different than the submission requirements. When I tried to create a custom preset, I got an API Failure error. Is there any way to fix that?
