After Ease eliminates the tediousness of setting up a bounce and elastic animation through its intuitive UI to set up a curve and apply it via expressions or bake keyframes onto your timeline. Use it on all of your selected numeric properties and even mask and shape paths.

Intuitive Tuning

Design your motion curves intuitively with a live preview and rich parameters.
Smart Baking
Bake the expressions into keys, tweak them the way you want.
Mask & Shape Paths
Go beyond Position and Scale and bake expressions on Mask and Shape paths.
