I have completed some finishing touches of Part 1 (such as feathering all the transition wipes), and am now in production of Part 2--the first point in the movie where elements from EP1 are used.
There are several sequences containing Jarjar that can be omitted entirely, but there are plenty that cannot. I will occasionally have to rotoscope him out, and it just happens that the first scene I want to edit was filmed with a (slowly) moving background. Here is the first frame of the sequence (Qui-gon stops talking here, so there is no character interaction).

NOTE: Obi-wan will be entering this scene soon, which is partly why I need it.
I am new to rotoscoping, but I understand the principle and method that can be used in Photoshop (or After Effects) when there is a 'clean' reference frame available for cloning. But what about the case when the target of deletion is ALWAYS in the shot?
I'm hoping that some of you have some experience with this and can offer suggestions, tips or recommendations for other tools that might help.
There's got to be a way to do it with good results.
