H3 Max

H3 Max is an AI video generator from MiniMax that turns a written prompt or a single image into a 5 to 15 second video with synchronized audio. It suits creators, marketers, and small teams that want directed camera motion and consistent characters without a full production crew.

Describe the shot or upload a starting frame, and the model renders the motion, sound, and pacing in one pass. A 5 second 768P clip takes about 3 seconds of model inference, so iterating on an idea stays quick.

Key Features

• Text and image to video: Start from a prompt or upload a begin image, with an optional end frame to guide how the shot closes.
• Synchronized audio: Ambience, effects, dialogue, and music arrive with the picture, timed to what happens on screen.
• Directable motion: Tracking shots, pans, push-ins, and fast follows stay aligned with the shot you described.
• Character consistency: Faces, clothing, and proportions can stay recognizable as the setting and camera angle change.
• Output controls: Choose 5 to 15 second durations, 480P to 1080P on H3 Max, 2K or 4K on standard H3, plus nine aspect ratios.
• Credit transparency: See the cost before you generate, and any render that fails returns its credits.

Who Should Use H3 Max

• Social media creators who need short vertical or square clips with sound for daily posting.
• Marketing and product teams that want quick concept video before committing to a full shoot.
• Agencies and storyboarders who use begin and end frames to preview timing and transitions.

Frequently Asked Questions

What is H3 Max?

H3 Max is a post-trained variant of MiniMax's H3 video model, tuned for stronger prompt adherence, audiovisual quality, and aesthetics. It runs in the browser and generates video from text or image inputs.

Is H3 Max free to try?

Creating an account is free. Free credits cover your first renders, then generation is charged per second of output, with subscriptions or top-ups available when you need more.

Does H3 Max work from images?

Yes. Upload a begin image to set the opening frame and optionally an end frame, and H3 Max generates the motion between the two moments. An end image requires a begin image first.

How much does an H3 Max generation cost?

Credits follow each render. H3 Max costs 10 credits per second at 480P, 16 at 768P, and 32 at 1080P, while standard H3 adds 2K and 4K tiers.
