Hi, I've only tried something like this a few times but mencoder which
comes with mplayer can do this. If you have a bunch of jpgs in a dir
you could do `mencoder \*.jpg -mf on:fps=3 -o output.avi -ovc lavc`
and it will make a video of it. i'm not absolutely sure but I think
mencoder can output only to an avi container, however it can contain
video in mjpeg, mpeg1, or avi.
