I've done some movies using XNview's (freeware graphics viewer) Create Slideshow function. I wanted to show trends through time with spatial data, so I just created a series of plots, named sequentially [paste() is your friend for all sorts of naming calistethics] then loaded them into XNviews slideshow dialogue and set a few timer variables, voila. Took like 5 minutes to learn how to do it and produce some executable graphics.
