Well LSD, I'm still tinkering with various compression schemes. It's been said, and I believe it to be true, that video compression is as much an art as a science. I have managed to squeeze a 5 sec. Bryce video clip(480x360,30 fps seq. file=86.8MB) down to around 2MB and still retain good image quality. I have had some decent results compressing to Mpeg4 in Premiere Pro, and believe it or not, coming out of Quicktime Pro. Also, XL Cleaner is a very good standalone compression app. This is one area(of many) where I would ask Mr. Dodobird for his advice 'cause he's really into animations and video.
