I'm trying to do a continuous track where drawings are coming in from the bottom and leaving the top, but still looking like they are attached to the paper. I am trying to create the illusion that these drawings are drawn onto the scroll. The first link below is an example of a track I already did; the second one is the raw footage of the one I'm currently working on... it is a little more complicated. I tried today, and it wasn't much of a success. What would be the most effective way to track this shot so I can composite my drawings in Ae?
