About ChronoKeys
ChronoKeys is a script from Freshmograph for After Effects that syncs keyframes to layers, allowing the duration of layers and precomps to be altered without losing keyframe precision. It includes Ripple Nudge and CTI Nudge for shifting keyframes and neighboring layers, as well as options to colorize keyframes, retime, auto‑extend, and duplicate precomps. Additional layout tools provide Align Keyframes, Stagger Keyframes, Equal Spacing, and keyframe retiming in frames or percentages via a settings panel. The script runs on After Effects 2026, 2025, and 2024. Version 1.02, released February 23, 2026, improves easing preservation, fixes a CTI Nudge bug, and adjusts nudge‑mode behavior for precomp retiming. A demo video is available from the developer.
