After Effects Expressions | Expression Magic

Explore the wiggle function to generate smooth random motion in After Effects. Adjust frequency, amplitude, octave, and amp mode, and apply to position, rotation, scale, opacity, or color.

Learn to control randomness with the seedrandom function using seed and timeless. Use a slider controller to place snowflakes within the composition and apply per-item wiggle.

Base the work area duration on the longest keyframe, make the duration a multiple of that keyframe, and loop the composition so the first and last frames match.

Master loop and loopout techniques to create seamless animations, using loop in, ping pong, offset patterns, and continuous loopout for smooth turtle motion.

Master looping with the remainder operator (%) in After Effects expressions to create keyframe-free loops using time-based math. Use a loop slider to control duration and apply it to rotations.

Learn how to use relative index in After Effects expressions to keep layers like clouds independent, apply time-based offsets with value at time, and create staggered motion for dynamic animation.

Learn to use parameter index to drive rotation offsets for multiple line shapes in one layer, and access higher groups with property group to fetch indices.

Harness the sine function to drive a looping bubble animation in After Effects without keyframes. Use time and time-based math to move the bubble upward with a wave pattern.

Learn the linear function to interpolate values and bridge parameter spans, linking properties without keyframes. See car motion, tire rotation, and role of ease in and out for smoother animation.

Design and implement shape controllers with custom sliders in After Effects, connect them to shape properties using linear functions, and create looping wave animations with repeater and trim paths.

Animate a whale using After Effects expressions, applying sine-based position and rotation, per-part offsets, and a blink via linear scale, controlled by sliders or a shape controller.

Explore RGB and HSL color models in After Effects expressions, controlling red, green, and blue with sliders and converting hue, saturation, and lightness to RGB for monochrome palettes.

Explore chapter nine of expression magic to animate a city by combining learned expressions into a dynamic scene, then rig cars and apply parallax for depth.

Learn to rig a car using after effects expressions, creating a scalable wheel system with a wheel size slider, anchor point adjustments, rotation tied to circumference, and dynamic body shake.

Explore the parallax technique in animation with expressions to add depth to 2d scenes, using a focus index and offset to drive motion and color changes.

Learn to bend objects with expressions using the CC bend effect and space transforms to create shaking. Link freq and amp to a sine motion, tune rotation, skew, and height.
