How to replace logos... on boxes for example?

[ejdge]

I need to replace some logos/writing on a box (copyright city!) and replace them with my own if possible. The box is coming out of a bag and moves from person to person. The footage was edited in FCP.

How would I go about doing this? Would I use AE or a different program? Thanks.

Your best bet is probably to create a 3d cube, use an image of the logo as the material. Then track the animation to follow the box in the shot. You'll have to manually mask out the bag and the hands, but if the shot isn't too long it shouldn't be too bad.

Although, this is just for a shot that needs 2D single point tracking, and I am not sure if that is exactly what you need.

If not, corner pinning with motion tracking may do the job. But as you said, a 2 point track may very well be all that it needed.
