Hello Mike, You might want to give "mencoder" a try. It usually comes with mplayer. I did play with it a while ago and was fairly happy with the results. Basically, the idea was to create many jpg files somewhere, which is not too hard using the %03d substitution described in ?jpeg. The rest is described here: http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-images.html
