LipDub
What is LipDub?
LipDub is an AI video localization platform for translating, dubbing, personalizing, and lip-syncing existing video content. Its proprietary technology matches a speaker’s mouth movements to new dialogue while preserving facial expressions, identity, and on-camera presence. The platform supports live-action, animated, and AI-generated footage in more than 80 languages. Creators, marketing teams, agencies, educators, and developers can use LipDub to produce localized content without reshooting the original video. Its main differentiator is combining translation, voice generation, and broadcast-quality lip sync in one workflow, with both a web platform and developer API.
How to use LipDub?
- 1. Create a LipDub account and upload an eligible video. 2. Choose a translation, personalization, dialogue replacement, or multi-speaker workflow, then review the script, voice, and timing settings. 3. Generate and export the localized video with translated audio and synchronized lip movements.
