After Effects expressions library
Life is easier with After Effects expressions, but writing them can be daunting. That's why our team spent hours on writing and testing the most useful After Effects expressions for you.

All expressions
Random Seeded Color Expression
Generating random colors consistently for text layers, ensuring each layer gets a unique color.
See expressionParent Position Offset Expression
Offsetting a child layer’s position by 100 pixels relative to its parent.
See expressionScale Based On Distance
Scaling an object based on its distance from another object in the scene.
See expressionRandom Rotation Expression
Randomizing the rotation of layers in a starburst pattern, between 0 and 360 degrees.
See expressionParent Scale Expression
Increasing the scale of a child layer by 10% compared to its parent layer.
See expressionWiggle with Seed Expression
Creating a wiggle effect on position with a set seed, ensuring the randomness is consistent across renders.
See expressionLooping Wiggle
Use this on the Position property of an object (like a floating balloon or drifting cloud) to make it gently move up and down in a looping, natural manner. This expression ensures the wiggle effect loops seamlessly every 3 seconds, preventing abrupt jumps.
See expressionRolling Ball Expression
Automatically rolling a ball that has position keyframes.
See expressionChange Value Based On Position
Changing the opacity of a layer if it crosses a certaing position.
See expressionRandom Position Expression
Randomizing the position of a layer within a 200-pixel range in both X and Y directions.
See expressionLayer Linking Expression
Linking a child layer’s position to its parent with a slight offset to create a trailing effect.
See expressionEaseIn Expression
Gradually increasing a layer’s scale from 50% to 150% over 2 seconds.
See expressionCenter Anchor Point Expression
Aligns other elements (like icons or graphics) to the exact center of a dynamically sized text box, keeping the layout balanced.
See expressionExponential Counter Up Expression
You want to animate a text layer that shows a price or number increasing exponentially, simulating the effect of fast-growing numbers.
See expressionTime-Remap Control Expression
Slowing down a video clip by half its speed using time remapping.
See expressionDynamic Text Box
Automatically resizes a background box to fit around changing text, ensuring consistent padding for labels, buttons, or captions.
See expressionValue Relative to Time Expression
Gradually changing the scale of an object from 0 to 100% over 5 seconds.
See expressionStrobe Light Expression
Making a text layer's opacity blink between 100% and 0% every second.
See expressionOscillate Expression
Creating a simple sine wave motion for a bouncing object or pendulum effect.
See expressionLoop Path
Use this to have an object (like a car or airplane) continuously follow a looping path, such as driving around a track or flying in a circular route, without needing to manually repeat keyframes.
See expressionDistance-Based Scale Expression
Control the opacity of a layer based on its distance from the point [500, 500]
See expressionOvershoot Expression
Adding an overshoot effect to the scale property, causing it to bounce back slightly after reaching its final value.
See expressionRandom Color Expression
Randomly generating a color within the RGB range for a flashing light effect.
See expressionParent Rotation Expression
Adding 45 degrees to the parent layer’s rotation to ensure the child rotates at an offset angle.
See expressionSine Wave Motion Expression
Animating the opacity of an object to pulse over time using a sine wave.
See expressionDelay Expression
Delaying the rotation of a gear object so it follows the rotation of a larger parent gear.
See expressionPosterizeTime Expression
Forcing a layer to update at 12 frames per second to create a stop-motion effect.
See expressionToComp Expression
Use when you want the 2D element to track the position of the 3D layer but stay flat and readable without 3D distortions.
See expressionSeedRandom Expression
Ensuring random values for each layer stay consistent over time based on their index.
See expressionConvertToWorld Expression
Aligning a spotlight’s position to the world space anchor point of another 3D object.
See expressionSmooth Expression
Smoothing out the jittery motion of a handheld camera by averaging out its position over time.
See expressionLookAt Expression
You want a layer (such as a 3D object or camera) to always face another moving object (the target layer)
See expressionClamp Expression
Ensuring that a layer's scale never goes below 50% or above 150%, no matter what animations or adjustments you apply.
See expressionNumber Counter With Separators
Neatly formats large financial figures (e.g., "1.500.000") from a slider for on-screen display.
See expressionLoopOut PingPong Expression
Animating the position of an object in a cosine wave pattern, creating a back-and-forth motion.
See expressionBounce Expression
A ball bounces to a stop after falling, using this expression to animate its bounce motion.
See expressionRandom Expression
Setting the opacity of multiple objects to random values between 0 and 100.
See expressionEase Expression
Smoothly increasing opacity from 0 to 100 over 1 second for a fade effect.
See expressionValueAtTime Expression
Delaying the position animation of a layer so it follows another layer with a slight lag.
See expressionLoopOut Cycle Expression
Looping the position of a bouncing ball to repeat its motion indefinitely without adding more keyframes.
See expressionWiggle Expression
Creating a subtle shake in a text layer to simulate a hand-held camera effect.
See expressionTime Expression
Rotating an object at a steady rate over time by applying it to the Rotation property.
