I didn't think much of these videos by their titles, but they're insane.

The first shows they're able to easily cut objects out of a video - as if they were filmed on a blue/green screen - without having to cut out the object in every frame. It's called the "Interactive Video Cutout".

The second shows how videos can be enhanced by using photos. Basically photos are higher quality, and thus more detailed, than video footage. By combining the two, they're able to "upgrade" the video quality. This is the really insane one, personally it seems too amazing to be true, but anyway: "Using Photographs to Enhance Videos of a Static Scene" (more info here).

Now if only that software was available for download... I would spend hours playing with it.
