Screen replacement with foreground moving object

I would really appreciate if someone will help me with a solution to my tracking problem.

I have a pull out shot with an ipad screen I have to replace. The guy’s arm is moving over the screen area and the track is picking up the movement even when I have tracked the arm and placed track layer on top.

 

Begining of the shot :

Expand the roto shape out from the guy’s arm for about 5+ pixels using the uber key. His hand isn’t completely in the shape. That should sort this out. If not, please let me know.

Cheers,
Mary

Hell0 Mary,

the expansion did help a bit and the screen track remains in the relative area, but it still wiggles/jumps alot.

I tried manually to adjust the track but it’s still too much all over the place…

Can you email me the shot at maryp@imagineersystems,com?
