TOPIC:

I NEED HELP. I HAVE A SCENE THAT HAS MUTIPLE COMPUTER SCREENS AND LARGE WINDOWS IN THE BACK GROUND. ALL THE COMPUTER SCREENS AND WINDOWS ARE GREEN SCREEN. THE TRICKY PART IS, THE WHOLE SCENE MOVES IN A KIND OF CIRCULAR MOTION, WITH ZOOM OUT AND ZOOM IN MOTION. I WANT TO BE ABLE TO PLACE MY GREEN SCREEN FOOT ONTO THE GREEN SCREEN AREAS AND HAVE IT LOCK INTO PLACE. MEANING, I WANT IT TO MOVE AND SIZE WITH THE MOTION OF THE ORIGINAL SCENE. ANY ADVICE...

THANKS

JOE

Motion should handle this fairly well. If it's too complex, I'd use Mocha and import the tracking data into Motion. To start I'd highly recommend the book "Apple Pro Training Series: Motion 5". It has a whole lesson on tracking with green screens that includes movement like you discribe. Very valuable book, very well done lesson on the subject.
