Sean Frangella shows how to track a 3D object from Cinema 4D into a live action shot, getting a believable final result.

There are all kinds of things needed to pull something like this off, from stabilization, to getting a solid and useable track and right down to rendering an objet that looks like it was directly in the live action scene – so there are a lot of topics that Sean covers here.
Sean shows how to stabilize the shot in After Effects to prep it for tracking, and then uses the Ae 3D camera tracker after a few adjustments to the contrast of the shot.
This gets to be a good example of the workflow integration between C4d and Ae, as Sean uses Cineware to exchange the mddl data to After Effects for easy edits and previews.
The tutorial also covers color correction of the piece, and rendering multiple passes for more flexibility in compositing. Sean sets a focus on rendering a separate shadow pass, ambient occlusion pass, and demonstrates some techniques for working with environmental reflections.
