I think I became able to export .mov files after I installed Quicktime 4. generally render out of 3D Studio or After Effects. If you use the Sorenson codec in the quicktime properies at 100%, it comes out almost exactly as smooth as Uncompressed .avis. But there is a littel problem that the .mov files I create don't run on anyone else's computer. I have tried others with as similar configurations as my own, but they just don't play. They work so great on mine. And they are usually smaller even then the Cinepak .avis. Anyone who can explain this problem will have m,y gratitude.
