I recently used AE to animate a composite of text over a handheld sign. I used the motion tracker to track the subtle motions of the person holding it. I used a null tracking layer which has the child text layer with the message as well the original movie as the backplate backplate. So, three layers in total. When I export an .xfl and import into Flash, I see all three layers, but I am not sure how to control them. The point of going to Flash is to attempt to convert the text layer into a Dynamic Text layer that can be changed on the fly. Is this a viable way to do this? Is there an easier way?
