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 demonstrates how to use one of our favorite expressions: Wiggle.
The ninth Apprentice course focuses on what we feel is one of the most powerful yet seriously underused portions of After Effects: Expressions. With expression, you can easily hook up parameters to follow each other, allowing you to keyframe just one property and have a number of other properties or layers follow along – in turn making it much easier to create complex, coordinated animations that are easy to update in response to client whims.
The movie above from the AEA09 video course demonstrates how to use the wiggle expression, which allows you to add a user-adjustable degree of randomization and imperfection to your animations. Wiggle auto-animates without the need for additional keyframes, and randomizes per layer allowing you to easily create swarming-type animations.
If you're completely new to expressions, a couple of years ago we posted a video overview to expressions from the second edition of our After Effects Apprentice book. If you are looking for more advanced expression applications, here is the index to our Deeper Modes of Expression series derived from our deeper Creating Motion Graphics book. Enjoy!
