Dynamic Text Reveal: Calculating text size with an expression

About This Class

Create shapes that match the size of text using Adobe After Effects expressions.

In this class, I'll show you how to animate the revealing of a dynamic text string. This allows the text to change, including the font or size, and have the animation automatically update. It'll let you create responsive essential graphics templates, and is a springboard to more complex interactions.

You'll learn how to use expressions to match the size of mask to a text element. I'll also show you a handy technique to add an animated easing to an expression using a placeholder object.

I'll go through these steps in the process:

Classic setup with text reveal
Calculating the text size and mask scale
