Eep... How to start on this one... I think you may have to do a little more investigation into how these technologies actualy work. 3D and video are as different as night and day. However, it would seem to me that you're in need of compositing software. Trust me, this is not for the beginner. Very expensive and a steep learning curve. I know of a number of ways to fake it, but none that I can explain easily. Anyone...?
