JPGVideo creates a video file from a series of JPG Files, these files can be from any source, as long as they are all the same size. This would make it a free alternative to other stop-frame animation programs. It would be necessary to shoot the jpgs on a digital still camera or a web cam.
Videos are exported as AVI files.
I have not tried this software yet, but it is worth a look.
