Here's how to apply squash and stretch to your animations.
Squash and Stretch is one of the main principals of animation, yet a lot of animators leave it out of their work. I’m going to show you the basics of this technique, and then show you how to apply it in After Effects. It will give you another tool to polish and finesse your animations, giving things more weight and oomph.
Make sure you check out the very cool Auto-Squash-and-Stretch rig that comes with this lesson, as well as access to a video where Joey breaks down in excruciatingly dorky detail how he created the expressions that drive it.
