Chris at posamation told me about a free program called Bink Compressor. You can get it www.radgametools.com. I compressed a 4 second 800x600 Avi (aprox 114MB) down to - Get this... 980KB!!!! That's about 115 to 1 Compression rate. There is virtually no quality lost. The program can convert most files and do it in reverse as well. It can also incorporate MP3's for sound. There are limitations: to watch a "Binked" video, you need the program on your Computer (download is Approx. 1MB) and having sound (or keeping the sound quality high) reduces the compression rate as well. On the upside, you can convert a Binked File to an .EXE which can run on any computer, even if it doesn't have the compressor. The down side of that format is that it can't be converted to a usable file once it's an .EXE file. It's a good tool to share your animations with others, but not for working with video. I hope this helps.
