Use Projected Plates To Clean Up Your Shot
In this tutorial we´re going to adopt a fairly common technique used in 3d compositing tools such as Nuke. We will start off by tracking the shot using the After Effects CameraTracker plug-in by The Foundry to get our 3d Camera properly solved. With this data we extend this shot and create a clean plate, which we´ll use to project onto our "proxy geometry" to clean up the shot. We´ll build a fairly simple "projector rig" with some expressions to make life easier.
