I've heard there is a script out there to render to image sequence . . . . where can I get this?

Also - if anyone could come up with a script to do thhe following I'd be grateful. Perhaps I can help out in return in some way?

This is what I'd want:
Split all VIDEO tracks at all marker points. That is it! I don't want audio tracks split - Just audio - and you can assume that the Audio and it's associated Video track would not be grouped. I always ungroup them for things I do.

I edit alot of music videos and sometimes listen to the music to make markers where I want camera changes - then manually do in to split all video tracks - would be nice to do this automatically!
