Where AI lip-sync earns its keep

/

Re-record a line in the booth, drop it in, the mouth re-renders to match. No more reshoots over a mispronounced word.

Amashusho

Give a silent portrait or AI-generated character a voice. Chain with /image-to-video/ to animate a still portrait first, then make it speak.

Guhuza

1.

Upload video

Clear forward-facing face works best. Multi-speaker, profile view, or rapid head turns reduce quality.

2.

Ijwi

Upload MP3 / WAV / M4A OR type a script and we'll TTS it with Kokoro (174 voices across 37 languages).

3.

Length-check

We warn if video and audio differ by more than 0.5 s. Auto-trim to the shorter length is checked by default.

4.

Guhindura

The premium lip-sync model re-renders every mouth frame to phonetic-match the new audio. Typical 30-second clip: ~1-2 min.

Guhuza - FAQ

Upload a talking-head video plus an audio track (or type a script for TTS) and the AI re-renders the mouth frame-by-frame to phonetic-match the new audio. Ideal for ADR, voice-over replacement, redubbing, or giving a silent portrait a voice.

No. Lip-sync runs on a premium model that is billed per second of video, so it uses purchased tokens only: sign-up bonus and daily-pool tokens do not cover it. The price scales with the length of the clip and is shown before you submit.

MP4, MOV, WebM up to 100MB. Clips under 30 seconds work fastest. Single forward-facing speaker gives the cleanest lip-sync; multi-speaker or rapid head turns reduce quality.

MP3, WAV, M4A up to 50MB. Alternatively, type a script and pick from Kokoro's 174 voices across 37 languages - we'll TTS it and use that as the driving audio.

Dubbing (/video/dubbing/) is a full pipeline: STT → translate → TTS → lip-sync. Lip-sync is just the last step - you provide the audio yourself. Use lip-sync when you already have the voice-over track ready; use dubbing when you want to translate and re-voice from scratch.

Typical: 30-second clip renders in 1-2 minutes. The banner shows a wait estimate once you submit, and the result lands in your dashboard - you can close the tab.

Not in one pass - the model locks onto one face. For multi-speaker scenes, cut into single-speaker clips, lip-sync each, then stitch back together in a video editor.

No. Input files are deleted within minutes of the render. The output is kept on our CDN for 24h (7d for paid users) at the share link.

Yes - POST a multipart video + audio_file (or video + text + voice) to /v1/video/lip-sync/. See /api/ for docs.
