One AI lip sync generator for videos and character images

The default AI video lip-sync workflow uses PixVerse Lip Sync: upload an existing character video, add a replacement audio track, and generate a new video with synchronized visible mouth movement. It is designed for turning audio into a lip-synced video, including existing-video localization workflows.

If your source is a still image, switch to P Video Avatar. That secondary workflow creates AI photo lip sync from uploaded audio or a written script, so you can lip-sync an image to audio while keeping the broader Lip Sync page focused on video first.
