Matchmoving: Object Tracking

Object Tracking With Tim Dobbert

Description

In visual effects work, it is common to have an element in the live-action footage that needs to be tracked. This is often the case when you need to add an effect to an actor's face, attach a CG object to a moving vehicle, or even add lip sync to an animal's performance. In this title, Tim Dobbert shows you how to track an object's motion using matchmoving software. You'll learn how to use the solution to drive an object's animation in Maya and how to properly evaluate your results. He'll also show you advanced object tracking techniques such as how to solve for an object's motion when the camera is also in motion, and how to invert the camera's motion with that of the object. Tim uses a variety of software packages for this lecture including Maya, Boujou, MatchMover and After Effects.
