Thank you very much for your reply, What i was hoping to do was this:

1. There is a fixed Medium shot of a man sitting at his computer looking at a screen which has a super imposed image over it.

2. A second man walks behind the man sat at the computer across the front of the Fixed medium shot.

NOTE: so what actually happens is the man walking across the shot covers the man sat at the computer and his screen, with his body as he walks past for those few seconds.

hope this is clearer

Many thanks

J.
