How it works

• Upload a video and apply lipsync to any segment or the entire clip.
• Use the Lipsync Studio to edit what anyone says after they've said it.
• Clone a voice or generate voice from text, or upload your own voice to synchronize with the video.
• Translate, edit, or personalize any video instantly with perfect lip-sync across languages.
• The model can learn a speaker’s unique style (lipsync-2) without requiring user-specific training data.

Use cases

• Localize films, shows, podcasts, games, and animations for multiple languages.
• Produce creative ads, dubbing, or multilingual content with consistent lip-sync quality.
• Dub content in real-time or near-real-time for rapid localization pipelines.
