Dave, What do you think about the DiVX encoder using mplayer/mencoder? There's binaries for *nix and Windows. It made rather nice compression on our 800x600 (didn't test higher, but am sure it'll be fine since most people use it to encode DVDs). It didn't drop sound at all, in our example. It didn't take too long to produce the nicer quailty movies, but much longer than simply
mencoder "mf://*.png" -mf type=png:fps=18 -ovc lavc -o output.avi And, I'm pretty sure mencoder can output to mpeg, given you DL the right codecs. If this sounds like a good option Google for 'mplayer and mencoder.' If not, I'd like to hear what else is out there. There's quite a bit of help out there for mencoder, so take a look. As a sample, our little PyMol movie (check http://129.109.119.159/~tree/movie/silent_arrestin_divx.avi or the directory that file's in, if I typoed) was encoded using a rather convoluted command line which I've since forgotten (but can dig up, if need be). Best Luck, -- Jason Vertrees
