Digital-Tutors : Rotoscoping Techniques in Nuke
In this series of lessons we'll learn how to use_the tracking, keying and masking nodes in Nuke to create a fast, robust rotoscope shape. By using each node for their specific strength, we'll be able to achieve production-quality results much faster than hand keying.
We'll begin this project by learning the basics of using trackers to speed up the rotoscoping process by removing camera jitter, translation, rotation and scaling. We'll then dive into our main project where we will use a combination of tracking, stabilizing, luminance keying and Bezier shape animation to create a clean mask for our foreground actor. We'll learn how_each of these different methods can be_used to speed up our rotoscoping workflow.
