Auto Lip-Sync, developed by mamoworld tools for After Effects, creates a mouth that automatically animates according to your voice recording.
Learning material comes through a set of tutorials. One walks through basic usage with a talking tree, while another shows how to apply Auto Lip-Sync to a moving object using a talking car example. A page collecting all the tutorials is also available, and there is a demo video as well.
The plugin runs across a wide range of After Effects releases, from CS4 through the 2026 version, covering CS5, CS5.5, CS6, the CC line and every yearly release up to 2026. The current build is version 1.12.003, released on November 11, 2025, which fixed online activation connection issues, updated the license framework, and resolved problems on Chinese systems. It is listed as free here; check the developer's page for current licensing.
