How to use easing for smooth animation in After Effects

Easing makes motion feel natural by controlling how speed ramps in and out. Without it, animations feel robotic. With it, they feel alive.

Steps to use easing for smooth animation

Select your keyframes, then right-click and choose Keyframe Assistant → Easy Ease, or just press F9. That’s the quick fix for most animations.

One more thing

Learn the shortcuts. F9 = Easy Ease, Shift+F9 = Ease In, Ctrl+Shift+F9 (Windows) / Command+Shift+F9 (Mac) = Ease Out. If you ever want to remove easing and go back to linear, Ctrl+Click (Windows) / Command+Click (Mac) on the keyframe.
