I don't know the 'technicalities' of the situation.. but I used Indeo compression on my babycakes animation and the file was 5Mb. The same file was 18Mb with standard MS .avi compression. I then 'Binked' it at 20% and it IMPROVED the color and contrast! I then made the .bik file into an .exe and it's only 1.1Mb babycakes.exe
