Expressions
& Snippets

Randomly varies the property's value over time.

Creates a continuous looping wiggle animation by smoothly transitioning between wiggle cycles.

Loops keyframes similar to loopOut(), but also supports Path properties.

Creates a seamless loop by combining loopIn and loopOut.

Creates an elastic bounce effect based on the velocity of the last keyframe.

Creates an elastic bounce effect for text animators, typically applied to the Amount property of an Expression Selector.

Linearly maps a value from one range to another, useful for linking properties proportionally.

Triggers animation based on layer markers. Set markers before applying.

Triggers forward and reverse animation based on marker duration. Extend markers using Alt + Drag.

Creates a text counter linked to a Slider Control, with adjustable decimal places.

Simple linear animation based on time. Control speed with multiplier.

Looping linear animation using modulo. Creates seamless repeating motion.

Smooth sine wave oscillation. Perfect for breathing animations and smooth back-and-forth motion.

Cosine wave oscillation. Starts at maximum value, useful for different phase requirements.

Combines multiple sine waves for complex organic motion.

Standard wiggle with easily adjustable frequency and amplitude parameters.

Creates a perfectly looping wiggle animation. Essential for seamless background animations.

Looping exponential growth that resets and repeats. Perfect for pulsing scale effects and repeated bursts.

Creates perfect circular motion using parametric equations. Great for orbits and circular paths.

Get universal position that doesn't depend on any parent layers. Converts layer's anchor point to composition coordinates.

The wiggle expression is one of the most common After Effects expressions. It wiggles an object across random values. This expression can be used to make your scene seem more natural.

Control wiggle behavior with a Slider Control, allowing you to keyframe when the wiggle starts and stops.

Make a layer revolve around the center of the composition.

Creates a natural overshoot/bounce based on the animation's velocity. Commonly known as inertial bounce.

Link rotation values between layers to create clock-like animations. Example shows hour, minute, and second hand relationships.

Loop and extend animation without adding additional keyframes.

Find a parented layer's true location in composition space rather than relative to its parent.

Create dynamic offsets by delaying the motion inherited from a parent layer.

Delay animation based on the child layer's index relative to the parent layer.

Initiate a wiggle effect starting at a specific time in the animation.

Start wiggle at the beginning and stop it after a specific duration.

Wiggle only between specific start and stop times.

Position and maintain one layer at a balanced distance between two other layers.

Create a trail effect where each layer follows the same path with a time delay.

Synchronize the Bulge Center of a Bulge effect with another layer's position, creating a magnifying glass effect.

Fade a 3D layer's opacity based on its distance from the camera.

Make a 3D layer invisible when it's facing away from the camera.

Flip a 3D layer horizontally when it's facing away from the camera.

Make a layer wobble at each marker with a decaying sine wave.

Match a camera's focus distance to the distance of a target layer.

Shows a slider-driven progress percentage across two lines. Add a Slider Control named “Progress” on the same layer.

Generates gentle floaty motion with the noise() function. Great for rotation or slider-based wiggle alternatives.

Drops each duplicated layer into a unique spot inside the comp while keeping the value static over time.

Combines wiggle with posterizeTime() to create a low-FPS jitter that still loops smoothly.

Uses Math.exp for a smooth fade during the last second before the layer’s out point. Apply to Opacity or Scale.

Offsets duplicated layers down the Y axis using their index, ideal for quick lists or step animations.

Automatically shrinks every second duplicate on the X axis to break up perfect repetition in a row.

Shifts the property backward in time by a set number of frames. Perfect for cascading animations.

Simple continuous rotation based on time. Change the multiplier to control speed (360 = 1 rotation per second).

Smooth sine wave oscillation. Perfect for breathing animations and smooth back-and-forth motion. One full cycle per second by default.

Rounds a number to a specific number of decimal places. Apply to Text Source Text. Link 'value' to a Slider Control.

Generates random position within composition boundaries. Updates every frame unless seedRandom is used.

Creates looping linear movement using modulo operator. Resets every 2 seconds and moves 200 pixels on X axis.

Gets layer index relative to a main controller layer. Useful for coordinated layer animations independent of layer order.

Creates sharp 0-100% opacity blinks with random intervals. Set property value to 50 for correct operation.

Calculates realistic wheel rotation based on the distance traveled. Apply to the Rotation property. Requires a Slider Control for the wheel radius. If the layer is a parametric shape layer, link the slider to an X Size or Y Size property.

Generates random values with Gaussian (bell curve) distribution. Values cluster more around the center of the range.
