MiniMax H3: Cinematic 2K Video, Sound Included
MiniMax's newest Hailuo model — text, image and reference to video, up to 2K with native audio, from 4 credits per second. Live on AutoDirector now.
MiniMax H3 is the third generation of the Hailuo video model line from MiniMax. It generates 4–15 second clips at 768P or 2K with sound produced in the same pass, and it is one of the most affordable cinematic-grade models available: 768P starts at 4 credits per second on AutoDirector.
Three modes are supported. Text to video takes a director-style prompt and an aspect ratio from 21:9 to 9:16. Image to video accepts a first frame and, optionally, a last frame, so you can lock both ends of a shot. Reference to video takes up to nine images, three video clips and three audio tracks as style, character and pacing references.
On AutoDirector, MiniMax H3 shares the same account, credits and generator as every other model — pick it from the model list, set duration and resolution, and the credit cost shows before you submit.

Why pick MiniMax H3
2K output
A 2K tier above the 768P default — sharp enough for landscape hero shots and full-screen playback without upscaling.
Native audio
Ambience, effects and rhythm are generated with the picture, so clips arrive ready to post.
First and last frame control
Image to video accepts a start frame and an end frame — lock a product's before-and-after, or a character's entry and exit.
Rich reference inputs
Up to nine reference images, three videos and three audio tracks in one request for consistent characters, motion and pacing.
Cinematic price point
4 credits per second at 768P — a 6-second clip costs 24 credits. Draft cheaply, then re-render the keeper in 2K.
Any length, 4 to 15 seconds
Per-second billing for every whole-second duration — pay for a 7-second shot, not a forced 10.
