In this NUKE tutorial we will learn how to use rotoscoping and luminance keying techniques. Along the way, we'll focus on analyzing different planar surfaces in mocha. Once our shapes are tracked in mocha, we will bring the tracking data into NUKE to build our rotoscope shapes. By the end of this tutorial we will have learned production-proven tips and tricks for compiling various luminance keys and rotoscoped shapes. Software required: NUKE 6.3v6, mocha 2.5.
