I was hoping someone might be able to help me find a solution for dynamically generating movies (Ideally FLV or MPEG) using a collection of jpeg/png/etc images. Does anyone know any good way to do this? So far, Ming, Pymedia and FFMpeg seem like the best possible options, but I've never used any of them and am not sure how suitable they are. I would also be up for doing it in actionscript/flex, but so far haven't seen any examples of this.

Any ideas?
