Engineered for Speed

Spring Physics

Calculates realistic decay, frequency, and amplitude to create natural bouncing overshoot on any property.

No Baked Keyframes

Applies a clean, lightweight expression, meaning you can still adjust your original two keyframes easily.

Property Support

Works flawlessly on Scale, Position, Rotation, and even custom Effect parameters.

Custom UI Controllers

Generates a pseudo-effect controller on your layer to adjust bounce parameters without touching code.

Frequently Asked Questions

The script looks at the velocity of your last keyframe. Just create two linear keyframes, and Bouncr will calculate the overshoot after the second keyframe.
Yes, once applied, a 'Bouncr Controls' effect is added to the layer where you can adjust Amplitude, Frequency, and Decay.
Yes, it successfully calculates overshoot for X, Y, and Z dimensions simultaneously.
Ensure your keyframes have distance/velocity. If you apply it to two identical keyframes, there is no momentum to calculate a bounce.
No, the expression is heavily optimized and adds negligible render time.
