In preparing for a more complex project, I've made a simple 3D scene using 3dsmax with a background and two spheres which are not visible just yet. The 3D camera then moves to view the two spheres which have a green circular area textured over each for color keying in after effects.

I then want to place two separate video clips (personal interviews) in each green area of the spheres, but I don't know how to do this. I don't want to add the video clips in 3dsmax as a texture cuz the quality would not be as good, since they would be textures.

I was thinking of having the 3d scene as the background layer in AE, and put clip1 in green area on sphere1 and use track points to track the movement of the sphere so clip1 would follow along inside sphere1's green area.

Am I on the right track with this, or can someone offer a suggestion on how to do this, as I haven't been able to get it to work?
