Hey Gareth
Thanks for getting back to me and thanks for the advice.
Yes this is a similar thing to what I want to do, except I( the camera) will be behind the ‘actor’ and the graphics will be squares in front of him which he will move to the edges of frame, so your interpretation of my explanation was good ! =)
I will hopefully be able to do a test this week, so I will try just doing this in FCP without motion and see how I go …
Thanks =)
