What is AI lip sync from a photo?

It takes one still portrait and one audio track, then generates a video in which that face speaks the audio with matching mouth movement. You are not editing existing footage - the motion is generated from the photo.

Can I lip sync or dub an existing video?

No. This model only animates a still image. There is no video input, so you cannot re-dub footage you already have, swap the language on a finished clip, or fix the mouth in a video you shot. If you want a talking clip, start from a photo.

Do I need to bring my own audio?

Yes. There is no text-to-speech step here - you supply the audio, either by uploading a file or recording from your microphone in the panel. Anything you would record for a voiceover works, including singing and non-speech sound.

How long can the clip be?

Between 5 and 14.8 seconds. Audio shorter than 5 seconds is rejected by the model. Audio longer than 14.8 seconds is not rejected - it is clipped to the first 14.8 seconds, and you are charged for the clipped length, not the whole track.

What kind of photo works?

A clear portrait with a visible, roughly front-facing face. The one hard constraint is aspect ratio: it has to be between 0.4 and 2.5, so very tall or very wide crops are rejected before you are charged. Square and standard portrait or landscape photos are all fine.

What does the transcription toggle do?

With it on, the model transcribes your audio and uses the words to guide mouth shapes, which generally sharpens spoken dialogue. With it off, it syncs to the audio waveform alone. Off can be the better choice for singing or for audio that is not speech.

How many credits does it cost?

Credits scale with resolution and the length of your audio: 10 per second at 480P, 16 at 768P, 32 at 1080P and 64 at 2K. A 10 second clip at 768P costs 160 credits. The panel shows the exact figure before you generate.

Clips made with this exact tool

Both clips below started as a single still photo and one audio track — nothing else. Turn the sound on; the point is whether the mouth matches the voice.

Talking-head ad read

12s

A 768x1024 portrait plus a 12.05-second voice track. The output came back at 768x1024 and 12.05 seconds — the canvas follows the photo, the length follows the audio.

Spokesperson intro

11.5s

Same setup, a different face and an 11.50-second read. Head movement and blinking are generated too, so it does not read as a static photo with a moving mouth.

Generated on MiniMax H3 Max Lip Sync at 768P. The portraits are AI-generated and the voices are synthetic — no real person is depicted. Both clips are compressed for the web; the originals are about 10 MB each.

What this lip sync model actually does

One photo, one audio track, and a clip whose mouth matches the recording.

A still photo starts speaking

Upload a single front-facing portrait and MiniMax H3 Max animates the mouth to your audio. No avatar to build, no rig to set up, no video footage needed.

Length follows your audio

There is no duration to guess at. The clip comes back exactly as long as the audio you gave it, up to 14.8 seconds, so the sync never drifts out at the end.

Transcript-guided mouth shapes

The model can transcribe your audio and use the words to drive the mouth, which sharpens consonants in spoken lines. Switch it off and it syncs to the waveform instead.

480P through 2K

Draft at 480P, work at 768P, and render at 1080P or 2K when the clip is going somewhere public. 2K is available on lip sync specifically.

How to make a photo talk

Three steps, and you bring your own audio.

Upload a face photo

One clear, front-facing portrait works best. The aspect ratio has to sit between 0.4 and 2.5, and the output keeps whatever shape you upload.

Add your audio track

Upload a recording or capture one from your mic. It needs to be at least 5 seconds; anything past 14.8 seconds is clipped to the first 14.8.

Pick a resolution and generate

Choose 480P, 768P, 1080P or 2K. The panel shows the exact clip length and credit cost before you spend anything, because both are set by your audio.
