3D object onto moving object in a video background

Hi everyone,

I have a question regarding the workflow and techniques for creating/compositing a 3D object created in C4D onto a moving object in the background filmed background.

I have experience with the workflow for adding objects into static footage using C4D and AE (you can see an example here: http://vimeo.com/42345884) and I understand the concept of tracking a moving camera except in my case the camera will be static.

In the scene, the camera will be static and there will be a skateboard moving in the shot from left to right. I need to have the 3D pig from the above example riding on the moving skateboard.

Any help would be appreciated. Thanks.

Jesse
