mencoder can do the job. See http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-images.html Don't work too hard on getting the list of files to work, at least be warned if you do. I put the resulting error message into Google and the first link was a patch with a question about where to send it. Helpful, if not encouraging. Listing the frame files on the command line does work; I am not sure when any limits on the length of the command line would strike. Note that I pass a collection of closures rather than forms; the hope is that it will be less resource hungry than creating all of the frames at one time.

Hello all, I have a growing number of annotated images and thought it would be nice to make a movie out of them. Following the example of an animated gif, I had a result a LOT faster than I expected, but the quality is really poor. Maybe setting a palette would help, but I'm wondering if there are other/better ways? Extra credit goes to any solution that can be driven from within Pharo or at least w/o littering my drive with lots of images, but I'll take what I can get if the quality is right. images2mpg has been mentioned in a few places, but it is playing hard to get.
