I would like to try to convert some pictures into a short movie, making use of a nokia 6680 mobile phone. (S60, v2, FP2)
Since it's easy to connect the mobile device with a PC, the movie can either be made automatically on the PC, but it would also be nice to find something to do it on the mobile phone itself. What would be the best solution (on PC or on phone)?

Also, which picture format is best for this use? PNG, JPEG, GIF, ...
What kind of movie should then be made? Flash-movie, MPEG-4, 3GPP, RealVideo,...?

If it is done on the mobile device itself, what should I take into account, is there already some information available somewhere, ....?
If it is done on a PC, what programs can be used to convert this pictures (most likely) automatically?
