Here is something no one has mentioned, and which I would test against, first: Set your frame rate to 30 FPS. Better yet, is 29.97, but try 30 first. Use a small frame size, best would be 320x240, even if it isn't the ultimate size. But keep the aspect ratio correct. I know that film rate is 24 fps, and we don't perceive flickering on the big screen, but for desktop video, 29.97, or 30, is better. No flickering then. In addition try this: Render to Microsoft Video for Windows UNcompressed frames. Don't choose any codec. If the frame size is 320x240 or around that, your computer will play them back fine, w/o jittering and dropped frames. I'm assuming you have a PC with a 1 GHz processor, or better, and I'm sure you do. My own practice is to render everything out of Vue as uncompressed frames. Then I can do virtually anything with the original file I want to, without further decompression and the resulting quality loss (jaggies, artifacts, and all that stuff). I can then create streaming Windows files (.asf, .wmv, etc.) or Real Video, or mpeg, or whatever. Even use mpeg2 and make a DVD. Hope that helps, Norm
