That's a killer idea! What I have been doing is this. I have been rendering everything at 720x480 so that I can burn a DVD with the final products. I'm not ashamed to admit I'm still kinda new at this so I don't have all the bugs worked out. So, if I know I want a sorenson 3 at 160x120 with a keyframe every 15 frames, I could render everything that size! WHOO HOOO!!! AJ
