Motion tracking and color keying with After Effects

Published by | Wednesday, December 14th, 2011

Motion tracking (the ability to follow the location of an object in a piece of footage, and use this information to stabilize that shot or animate other layers) and color keying (the ability to make a green- or blue-screen background transparent so that you can replace it with a new image) are two essential visual-effects tasks you need to learn if you want to take your After Effects skills to the next level.

In After Effects Apprentice 12: Tracking and Keying, Chris Meyer covers tracking and keying basic and essential skills including a quick tour of mocha, the third-party tracking software that is bundled with After Effects, and an introduction to The Foundry’s KEYLIGHT, an Academy Award-winning keying effect that is also built into After Effects.

Throughout the course, Chris shows you how to use the motion tracker and stabilizer built into After Effects, and offers advice on how to handle a variety of shot scenarios. He also discusses how to use tracking and keying to track a greenscreen shot with a handheld camera and replace its background.

While practice is the secret to mastering your tracking and keying skills, getting to look over someone else’s shoulder as they perform these tasks is a great way to jump-start your learning curve.
