This is my video idea (please don't steal it xD):
I'm going to have paper boxes of different shapes and colors. I want to motion track different clips to the top of each box so that it looks like it's actually on the box. Then as I take some boxes out and switch em for other boxes, the clip would follow that box out of the screen and a different one comes in with a different box.
I can print little "+" signs on the corners of the boxes if i need to do that.
Does Voodoo do this? Do I need Blender too?
