Lynda Screen Replacement with After Effects and mocha AE
One of the most common visual effects tasks is to replace an image or video in a shot with another—be it a computer screen, a picture on a wall, a bumper sticker on a car, etc. This project-oriented course walks you through the major steps of replacing screens in After Effects, including tracking a screen in mocha AE, matching the new display to the depth-of-field blur and lighting of the original shot, and then cutting out a hand obscuring the screen using the Roto Brush and Refine Edge. A bonus movie at the end of the course discusses alternative approaches, including a demonstration of using reversible stabilization in Warp Stabilizer VFX for the tracking portion of the shot.
