Anthony, I would definitely suggest using a different codec for compression, as Microsoft Video 1 is limited to 1000's of colors, and the compression ratio is really outdated (originally written for Windows 3.x) I would also shy away from Cinepak, as it has really bad output quality. I wholly agree with MadRed about rendering to uncompressed video, and then trying different compression techniques using another video editing app such as Premiere, or ulead video studio. I have had pretty good luck with Indeo 5.0 video codecs, any of the quicktime (Sorenson etc.) or Motion JPEG all give a decent compression ratio, and excellent output quality. To add any of the above codecs to your rendering output options, just download and install the latest version of Quicktime (for .mov file output which is much better compression ratio to quality output than .avi) or download and install the latest Indeo codecs from: http://developer.intel.com/ial/indeo/video/driver.htm Hope this helps, co(V)(V)union
