AI Lip Sync for Talking Videos
Upload a face-forward clip, add a script or audio track, and create a new version where the mouth movement follows the voice.
Turn one talking clip into a new voice version
Use AI lip sync when the face, framing, and product context already work, but the spoken line or language needs to change.
Use the complete workspace for asset library clips, voice setup, task history, downloads, and result management.
Create new spoken versions from one clip
AI lip sync is useful when the clip already has the right person and scene, but the voice, script, or language needs to change.
Creator ad variants
Test new hooks, offers, and scripts while keeping the same talking-head ad scene.
Localized voice tests
Pair one clip with different language scripts or voice tracks for market validation.
Product demo updates
Refresh a product explanation or offer without reshooting the presenter.
Social proof edits
Adapt testimonials, founder messages, or spokesperson clips when you have rights to the footage and audio.

Built for voice changes, localization, and ad testing
CreatOK keeps the lip sync workflow close to real creator production: source video, voice input, model choice, and duration handling.
TTS and uploaded audio
Start from a written script or bring your own voice file when the audio is already approved.
Model choice for quality fit
Choose from the same lip sync model options used in the full CreatOK workspace.
Duration alignment controls
Decide whether the result trims, loops, or preserves silence when audio and video length differ.
Rights-aware production
Use clips, voices, and likenesses you have permission to edit, especially for ads and public distribution.
AI lip sync questions
Practical answers for creators, marketers, and ecommerce teams adapting talking videos.
Can I use AI lip sync for free?
You can start with a free trial and continue in CreatOK when you are ready to generate, review, and download synced video results.
Can I use text-to-speech instead of uploading audio?
Yes. The lip sync workflow supports a TTS script as well as uploaded audio, so you can test a new voice line before using a final recording.
What clips work best for lip sync?
Face-forward clips with visible mouth movement, steady framing, and a clear subject usually give the most useful synced results.
Can I localize one creator video into another language?
Yes, when you have the right to use the video, voice, and script. Use a translated script or audio track to test localized spoken versions.
Will the original video scene change?
The workflow is designed to keep the source context while updating mouth movement to match the new voice. Results still depend on face visibility, motion, and audio timing.
Can I use the result commercially?
Use only footage, voices, scripts, and likenesses you own or have permission to use. Avoid impersonation, unauthorized celebrity likenesses, and misleading edits.
