Back when this was new, I remember discussing it on Hackaday or somewhere. Someone remarked that they were amazed that the video could pick up on the motion at all, the video looked still to them. I responded that it really was still--the demo video had been lossfully encoded for the web (re-encoded by YouTube?), and the encoder took out the subtle changes. I suspect that most footage already stored is similarly lossfully encoded, and that this technique isn't possible on it.
