I tried adding in the animated Gif support, and it was way too difficult. MS doesn't support it directly, so any support has a number of libraries included. I believe that there are directions posted on the Matrix site on how to create Gif animations.
Sorry, maybe for another version. It's still a work in progress, but here's a preview of a small avi. I support small and ultratiny.
One thing that I'm doing is hardocding that I don't want 'keyframes.' Keyframes are basically a full copy of the image designed to allow the encoder to recover is anything is Fubar in the file. That makes these a little more fragile, but a LOT smaller. In this example, the Arracount Avi is about the same size as a single JPG. I did drop the video quality a little for the AVI, but that's still pretty neat I think.
