Anytime computer-generated imagery (CGI) needs to be placed into a live-action sequence, or vice versa, a matchmove is required. But what exactly is matchmoving? Matchmoving is the process of matching CG elements into live-action footage. As a result, it’s a crucial part of many visual effects shots. Despite its importance, it is completely invisible in the final shot—that is, if it’s done right.
In this chapter, I explain the key steps of a matchmove and how matchmovers work with the rest of the visual effects team. I’ve also included a tutorial that will help you become comfortable working with cameras and perspective.
