When I look inside an .AVI file which was output by Poser, I find that its component frames seem to have been compressed by a method called "Microsoft Video 1", and the text "CRAM" appears in the "type of compression" field in its "strf" chunks. Please where can I find the internal details of this "CRAM" compression method? How can I translate an image between this CRAM mode and ordinary uncompressed .BMP? I have got nowhere by looking in various WWW information sites, or trying to decipher the method directly by comparing a compressed file and an uncompressed file. I merely need the translation method :: I can write Windows programs.
