I tried posting here last week, but I am not sure if I am still being moderated, so it didn't seem to appear.
I have a short clip of some garage doors closing. I need to 'clean-up' the garage doors so have screengrabbed the final frame and cleaned it in Photoshop. Despite following several tutorials and Googling-like-crazy, I am not sure of the best process to use in AfX. I tried tracking and then clone-stamping but without much success (there are several dirty bits). I tried masking the clean bits of doors and tracking these (with tracked scale and position) but I couldn't get it to work.
If anybody has any pointers, that would be great. Here is a link to my source file.
My suggestion is to straighten out the door only in photoshop to a square image, then place it over the footage in AE with the corner pin effect applied to make it align to the door at the beginning and end points of the motion. Then easy ease the end. You don't have to follow the motion of the original door exactly, you just need make sure it doesn't show underneath the fake door during the animation. Then you can duplicate the original layer, bring it above the animated door and mask it at the door's left edge to make the moving door go behind it. Finally add a soft shadow at the edge between the two to give it some depth.
