The spring’s state (velocity, displacement at each segment) is updated sample-by-sample, allowing audio-rate modulation of parameters.
: This tool creates a dynamic, delayed follow-through relationship between two layers. Imagine a character's ear flopping behind as its head turns—this constraint automates that effect with a realistic springy delay.
: Keep in mind that for complex deformations (like Bend or Bulge), it’s best to use solids, footage, or pre-composed layers.
Click the Create Spring button on the Springy FX panel. The script will instantly inject an expression framework and generate a standard After Effects Effect Control panel named Springy FX . Springy FX v1.0

Springy FX v1.0 is an After Effects extension by Fremox designed to automate secondary motion—such as jiggling, overlapping, and "squash and stretch"—based on existing keyframed transform properties. The toolset includes nine distinct tools, such as Parent Constraint, Bend, and Liquid, which allow for customizable physics control through a dedicated "Spring Constraint CTRL" layer.

Because Springy FX generates standard After Effects expressions, the results are highly compatible and shareable. The developer, Fremox, provides extensive learning material to help users master the tool:
Throughout the piece, I employed a range of sound design techniques to create the spring-like effects: [ u_i^n+1 = (2 - \alpha - \beta)
Creating dynamic, organic animations in Adobe After Effects often requires hours of tedious keyframing. changes this entirely by introducing an efficient, toolset-driven approach to secondary motion. This comprehensive guide covers everything you need to know to master this powerful After Effects extension. What is Springy FX v1.0?
The combination of 9 different tools means you can achieve everything from subtle, natural jiggles to extreme, cartoonish squash and stretch.
Springy FX v1.0 isn't just another plugin; it's a dedicated toolset from Aescripts designed specifically to inject into your After Effects projects. It automatically analyzes your existing keyframe animations and generates secondary movements like overlapping actions, stretch and bounce effects, saving countless hours of manual work. Widely compatible with After Effects versions from CS6 to CC 2017 , it works with solid layers, footage, and precomps, bringing an authentic "springy" feel to motion design, character animation, and even static graphics.
: Adds a "whippy" or leaning effect to layers as they move sideways.
