I just finished creating my first stop-motion short using Ubuntu 12.10, openshot, and the "stopmotion" app from the repositories. It was an exercise in patience in more ways than one, because basically stopmotion segfaults on me constantly. It may run fine for 150 frames and then suddenly crash, and then crash after every third frame, or after saving, or as soon as I turn on the camera. There's no rhyme or reason.

Is there a better program out there for doing stop-motion work?
