Chapter: Compositing Tools and Techniques

Topic: Scripting or Expressions

In this tutorial we?re going to explore the wonderful world of the powerful new expression controls which Adobe introduced with After Effects 5.5. We?ll look at several different ways that expression controls can be useful in your projects. First we’ll examine the most straight-forward use of expression controls, which is to use them as a manual adjustment ?master? control to help you set up a comp just the way you want it. Then we’ll explore using expression controls as master animation controllers. Next we’ll examine how you can use an expression control as a limited type of global variable to distribute information to expressions in other layers. Finally, we’ll have some fun using expression controls to create the world?s greatest cameraman. That’s a lot of ground to cover, so let’s get moving!
