As we mentioned earlier, we've been busy this year creating an extensive, multi-course video training series based on our popular beginner's book After Effects Apprentice. Each course has two or more movies that are free for all to view; we're re-posting those videos here on PVC to make sure you don't miss them. This movie provides a quick start on how to use Imaginer Systems' mochaAE – a powerful 2.5 planar motion tracker that comes bundled with After Effects (but which has a quite un-After Effects-like user interface):
The twelfth Apprentice course (available both by subscription to lynda.com and stand alone from Focal Press/Class on Demand) – covers two core visual effects tasks you need to learn if you want to take your After Effects skills to the next level: Tracking and Keying. In this course, Chris shows you how to use the motion tracker and stabilizer built into After Effects, with loads of advice on how to handle a variety of shots. On the keying front, Chris demonstrates the basic workflow for The Foundry's Keylight, which is also bundled with After Effects. By the end of this course, you will be combining these two skills to track greenscreen shot with a handheld camera, and replace its background.
In the movie above, Chris gives a quick tour of the third-party software mocha that is bundled with After Effects. In many situations – such as when performing a perspective corner pin track, attempting to follow objects which travel partially off screen, or dealing with “obscuration” where another object temporarily moves in front of the one you are trying to track – mocha often yields far superior results to the tracking built into After Effects. In the movie above, Chris demonstrates using mocha for a perspective corner-pin track.
Chris also demonstrated mocha as part of the After Effects CS5 New Creative Techniques course on lynda.com. In this alternate movie – shared below – Chris demonstrates a more challenging case of tracking indistinct features on a distant wall with a man running in front:
FTC Disclosure: We make a bit of money whenever you purchase one of our courses from Class on Demand, or have a lynda.com subscription and watch one of our courses. We do not make any money from either when you watch these free videos. We've worked with Adobe over the years, and they give us free access to their software in exchange for testing and consulting, but they did not subsidize the creation of these videos or the book they are derived from. We're just trying to pay the bills by sharing what we've learned from using After Effects in the real world since version 1.0.
