Expressions in Adobe After Effects are designed to modify the values of a property. What exactly are expressions and what do they do in After Effects? How do they differ from keyframes? In this movie, author Luisa Winters gives you things to keep in mind when adding expressions to your After Effects project.
- What expressions do is modify the values of a property.…Sometimes they do so in time, like with keyframes,…and sometimes, they do so globally,…like when you change the value of something…but don't keyframe it.…Sometimes, expressions refer to other values…in the composition, like layer stacking order,…or the specific values of different properties.…We write expressions like we write code…because expressions are code.…
Also, many commercially available templates…use expressions and you can also modify these…however you like.…You can add expressions to properties…
