For example, you could have the rotation of one layer determine the position of another layer. Drag the parameter pick whip in the Parent & Link column from one parameter to another to tie parameters together, so one parameter controls another.Use a parameter pick whip to link parameters For our example above, the layer would move 10 times a second, and only adjust 5 digits in any direction for the parameter. The second number is how much that wiggle will change numerically. The first number in the wiggle expression is the number of times the parameter will wiggle per second. Click outside of the text box to apply the wiggle expression. Then, click in the Timeline to open a text box and type wiggle followed by two values in parentheses, like (10,5). To create it from scratch, apply an expression and select it in the Timeline. The wiggle expression is a great one to start with.Option-click (MacOS) or Alt-click (Windows) the stopwatch of any parameter to apply an expression to that parameter.Look for the Expressions Language Reference chapter.What you learned: Multiple methods for applying expressionsĮxpressions are a fast way to create animations that would otherwise seem much harder to create using keyframes.

If you think you might need this kind of assistance, please contact me. Partial list of clients: Adobe, Showtime, CBS, NBA TV, MTV, The New Blank, Jugnoo, Ozone, Tendril, and Little Airplane. I also have experience with scripting for Photoshop, Illustrator, InDesign, and Flash. I've also built a lot of automation tools for animators.
Most of my projects involve scripting, but some require complex animation rigging via expressions. I also do a lot of math-intensive projects. I've set up a bunch of real-time operations, where a script waits for a job to come in via an XML file and then loads the appropriate project, does the media and text replacement and renders the result on the fly. Sometimes this will amount to reading a monthly schedule and generating promos for the entire month. I do a lot of workflow automation where the client needs a script to read in a large amount of data and use that data to drive media and text replacement and batch render (or queue) all the variations. I've been doing freelance script and expression design pretty much since those features were added to After Effects. If you have comments, questions, or find an error-please contact me. I have an enormous backlog of content, and I'm trying to organize and present it in a way that should answer many questions that come up repeatedly in the AE forums.
