Hasta La Motion!

I’m trying to track a shot where some guy holds a green piece of paper with some track marks on it. I’m trying to composite a photo on top of that lil mini-greenscreen (unfortunatly it wasnt possible to have the actor look at the real photo so thats why we had to go with this complicated mess). there’s a bit of movement and a bit of paper bending involved. we’ve been trying for ages to track it in mocha but all we get is a really really shaking track. plus I cant seem to find out how to adjust the photo to the bending that happens when the actor holds the green sheet in his hands.

anyone’s got any idea on how to approach that successfully? THANKS ALOT!

cheers!
