What MiniMax H3 Max Lip Sync is great for
A consistent face delivering scripted lines across a series.
It turns a still portrait and an audio track into a talking video, animating the mouth so it follows the soundtrack. The face comes from your image and the voice comes from your audio.
MiniMax H3 Max is tuned for speed and mainstream 480p/768p output, returning clips in seconds. The standard MiniMax H3 renders higher-resolution native 2K but takes longer. Choose Max for rapid iteration, and MiniMax H3 when you need maximum resolution.
Upload a portrait, add an audio file between 5 and 14.8 seconds, and generate. The model matches mouth movement to the sound and returns a clip the same length as the audio.
2 things: a still image to act as the first frame, and an audio track. A transcript is optional and can be added to guide the result.
The audio sets the length, from 5 to 14.8 seconds. There is no separate duration control.
480p, 768p, 1080p or 2K. The aspect ratio is taken from the image you upload rather than set separately.
MiniMax H3 Max generates video from a text prompt or an image. Lip Sync is the variant built for one job: syncing a face to audio you already have. Both run in the AI Playground and you can switch between them from the model list.
