This is actually a more generic question, although I am using Premiere Pro CS5 to work on this problem.
Basically, what I want to do is plaster a still image on a moving background. The issue is that this image needs to move relative to the background so as to give the illusion of being still. An example would be imagining playing Super Mario World, and Mario is running across the level. As he moves, he stays centered, but the background moves. What I am attempting to do would be the equivalent of implanting a still image onto the background of this video game, and having it move with the background so that it appears to be a part of it.
Is this sort of thing even possible? And if not with Premiere Pro, does anyone know what software might be good for this task?
