Boris Continuum 11 came out recently and in this tutorial, Dan Harvey gives an overview of how the keying and masking tools work in Vegas Pro.
Continuum is the VFX toolset that helped Ezra Edelman’s O.J.: Made in America win the Academy Award. A plug-in collection for Adobe, Apple, Avid and OFX host applications, Continuum features range from Image Restoration, to Extruded Text, titling and 3D Objects, to Chromakey and Compositing, Particles, and Image Stabilization. Continuum serves NLE editors and Compositors alike with the newly integrated Masking and Planar Tracking Pixel Chooser powered by Academy Award-winning Mocha technology.
