Does anyone know of a program that can cut a moving object out of a video??? Kind of the same thing as a keying effect but only if you don't have a green screen. I see it done all the time with hollywood, mostly in commercials. It almost seems like they have a program out there that can recognize and object in a video and cut that out. Just like this years superbowl intro, they had footage of football players from previous games but they were cut out. I know they don't do it frame by frame, it would be too tedious, there must be something out there...

Any advice would be awesome!

thanks
