You might want to look at Bink! from Rad Game Tools (www.radgametools.com). It's targeted to game developers who need to compress video sequences for games, but it is a handy general-purpose compressor. Their philosophy is that they don't mind taking a while during compression, as long as decompression is fast. I used Bink! to compress a 35-second 600 x 600 animation from over 1GB down to 500K. It took about 45 minutes to compress. You can also create self-extracting Bink! files, for those people who don't have Bink!. (Of course, since they are .exe files, they will make people nervous if you post them. You might be beter off just posting the link to where they can download Bink!) The best part is that Bink! is a free download, as long as you don't mind the Bink! logo popping up at the end of your animation. (And if you don't mind paying a bunch, they will sell you a version without the logo.) Lynn Grant Castle Development Group
