I did the following clip earlier this year Click Here to download. Its not very good. I never used a specific compositing program like AE for this clip. I used Maya Live to track my camera movements, then did a very simple test to see if it would track ok with a 3D object in the shot. I exported the rendered layers in TGA format from Maya, then imported them directly to Premier. Video 1 - Real Footage Video 2 - Shadow Layer Video 3 - Robot Layer I still have heaps to learn about Modelling, Animation, lighting, you name it! If you used AE you could get much better results. Have a look at this thread if you get a chance. Cheers Paul
