LipsyncTool is an After Effects script that creates smooth, interpolated lip‑sync animation using marker‑synced keyframe presets, without holds or expressions, by applying viseme presets from a dedicated layer to your main artwork.
Developed by Mikhail Ivanchuk.
About LipsyncTool
LipsyncTool automates lip‑sync animation in After Effects through smooth interpolation driven exclusively by keyframes linked to timeline markers. Users place viseme shapes—such as A, E, O, M—on a preset layer, assign markers, and then apply the preset to the main art layer. The markers trigger the appropriate viseme keyframe sets, supporting range markers and multi‑frame sequences, while the motion remains expression‑free. Version 1.0, released on 19 June 2025, runs on After Effects versions from CC 2018 through the 2025 release, including CC 2019, CC 2020, CC 2021, CC 2022, CC 2023, and CC 2024. A demonstration video is provided by the developer.

Frequently asked questions
Does LipsyncTool work with After Effects 2025?
Yes. LipsyncTool lists compatibility with After Effects 2025 and also supports versions from CC 2018 through 2024, covering CC 2019, CC 2020, CC 2021, CC 2022, CC 2023, and CC 2024.
Is LipsyncTool free to use?
The catalog marks LipsyncTool as free, but users should verify the current licensing terms on the developer’s page before use.
How does LipsyncTool trigger viseme animation?
Viseme animation is triggered by timeline markers. Visemes placed on a preset layer with markers are applied to the main art layer, and the markers invoke the corresponding keyframe sets, including range and multi‑frame markers.
Does LipsyncTool rely on expressions?
No. LipsyncTool does not use expressions; it creates smooth interpolated lip‑sync via marker‑synced keyframe presets without holds or expressions.
