After Effects Size Expressions: Dynamic Text, Scaling, Images and Debugging

An After Effects Expression Class by Edaqa Mortoray

Templates need lots of size expressions, let's figure them out.

Working with sizes in expressions can be a bit of a challenge. In this class I'll unravel some of the confusing bits about sizing and scaling content. You'll learn how to dynamically size elements, a key aspect to building responsive templates.

Together we'll work through a variety of size concepts:

  • Your friend sourceRectAtTime
  • The difference between Size and Scale
  • Converting between percentage and ratios
  • Working with Text and Images

With this knowledge you'll be able to dynamically link the sizes of items, based on content size, text size, and any scaling.

Have you ever been wondering why we divide and multiple by 100 so often in expressions? I'll explain that do, in the 100% chapters. You'll even learn some techniques to debugging expressions.

If you're new to expressions, you may also find my introduction to expressions class helpful.

Also, if you're like me, you're getting a bit lost with all those assets, clips, and folders, check out my friend Sonja's class on being efficient in After Effects.
