Use expressions in Adobe After Effects to save time animating motion graphics. Learn how to add and edit expressions, use variables, and assign random values.
- Hi, I'm Luisa Winters. Welcome to Adobe After Effects Guru Expressions. Expressions are an incredibly powerful feature in After Effects. Expressions are a way to affect the values of properties using lines of code instead of keyframes, so using expressions is usually faster and cleaner than using keyframes. Not only that, but if you do need to change some of the parameters of the animation, changing a value on an expression is usually much faster than changing many keyframes.
I will start this title by going over adding simple expressions and commenting them and of course, modifying the values. Then, we will go over using and changing expression dimensions, variables, and using the Expression Language menu, which is built in After Effects. Finally, we will go over some of the most commonly used expressions. It is my hope that this title will get you started in the wonderful world of expressions in After Effects, and that little by little, you will start incorporating expressions in your workflow to make your After Effects work easier and more effective.
