Аналіз експресії для затухаючих коливань в Adobe After Effects

Abstract

Expressions in Adobe After Effects optimize animation by reducing keyframe dependency and enabling smooth transitions. This paper explores an expression that simulates damped oscillations using harmonic motion with exponential decay. It adjusts amplitude, frequency, and decay to create realistic motion effects. The expression analyzes keyframes and applies oscillations when within a set time threshold. Widely used in motion design, it enhances natural movement for text, graphics, and UI elements. Applications include bounce effects, automated motion, and object appearances. This approach improves animation quality while offering flexible parameter adjustments.
