AI Lip Sync Generator
Lip sync takes a video you already have and re-times the mouth to new audio. Dub a clip into another language, fix a fluffed line, or make a character sing without regenerating the whole scene. The composer below needs a source video and an audio track, which you can upload or generate from a script. The sections after it cover inputs, timing and the rights reminder for songs.

How it works
- 01
Upload the video
A clip with a visible face, filmed or generated. Filmed on your phone or generated here.
- 02
Add the new audio
Upload a recording, or type a script and choose a voice.
- 03
Generate
The mouth, jaw and surrounding skin are re-rendered to match the new track, frame by frame.
What it handles
Speech and dialogue
Replace a line or a whole monologue while the performance stays.
Translation and dubbing
Keep the speaker's face, change the language.
Songs
Sync a performance to vocals. You need rights to the recording you use.
Generated voice
No microphone needed: write it, pick a voice, sync it.
Timing
Sync is computed per phoneme, so fast speech stays aligned.
Best inputs
- Mostly front-facing faces; extreme profiles reduce quality.
- Steady footage without motion blur across the mouth.
- Audio without background music for speech; for songs, a clean vocal stem if you have one.
- Match the audio length to the clip, or trim in the composer.
Rights reminder
Use audio you own or are licensed to use. Commercial recordings and other people's voices need permission, and impersonation is against the guidelines.

Frequently asked
- Does lip sync work on side profiles?
- Best results come from faces that are mostly front-facing and not obscured. Extreme angles and hands over the mouth reduce quality.
- Can I sync a whole minute of video?
- Maximum source length depends on the routed model and your plan; the composer shows the limit and the cost before you commit.
- Is the original audio kept?
- The new audio replaces the speech track. Background music can be re-added in your editor after download.
- Do I have to pick an AI model?
- No. Choose a style preset such as Fast, Cinematic or Story and the router selects the best available model for that intent, aspect ratio, duration and the inputs you attached. If a model is degraded, the router falls back to a comparable one without charging you twice. Advanced users can still pin a specific model.
- How much does a generation cost?
- Every generation is quoted in credits before you confirm, based on the routed model, duration and resolution. Credits are reserved when you start and released automatically if the generation fails, so you only pay for what completes. Plans start at $4.99 a week and include a credit allowance; subscribers can top up with credit packs.
- Are my generations private?
- Yes by default. Everything you generate lands in your private library. You decide per creation whether to publish it to the feed, share it unlisted, restrict it to followers or keep it private, and whether others may remix it.
- Can I download the videos?
- Yes. Every completed generation can be downloaded in full resolution from your library. Files are stored permanently on our own media storage, not on the provider's temporary links.
