H3 Max AI

What is H3 Max AI

H3 Max AI is a web-based video generator powered by MiniMax H3 Max, a tuned build of MiniMax H3. It turns a text prompt or a single still image into a 5–15 second video clip with synchronized audio, including sound effects and spoken dialogue. The tool offers both image-to-video and text-to-video modes, with options for resolution (480P, 768P, or 1080P), duration, and number of outputs. It is designed for quick iteration: write a prompt, generate a clip, review it, and refine.

How to use H3 Max AI

1. Choose a mode: Select either "Image to video" or "Text to video" from the generator tabs.
2. Provide input:
   • For image to video: Upload a start frame (required) and optionally an end frame.
   • For text to video: Enter a prompt describing the scene, motion, camera, and dialogue.
3. Set parameters:
   • Choose a model (e.g., MiniMax H3 Max Turbo).
   • Select resolution (480P, 768P, or 1080P).
   • Adjust duration (5 to 15 seconds).
   • Choose the number of outputs (1 to 4).
4. Generate: Click the "Generate" button. The cost in credits is displayed (e.g., 15 credits for a 5-second 480P Turbo take).
5. Review and refine: Watch the generated clip, then adjust the prompt or settings and generate again.

FAQ

Is MiniMax H3 Max free to try?
Signing up grants 20 credits and a 5-second 480P take on MiniMax H3 Max Turbo costs 15, so your first Turbo draft is covered. Turbo at 768P is 25 credits and the non-Turbo MiniMax H3 Max at 480P is 35, so the version you keep needs a plan — $19.90 a month loads 1,500 credits.

How is H3 Max different from MiniMax H3?
H3 Max is a tuned build of MiniMax H3 with stronger prompt adherence and better aesthetics. In Design Arena's August 2026 image-to-video rankings it scored Elo 1,341 to the base model's 1,333, taking the top slot.

How many credits does a MiniMax H3 Max video cost?
Each second costs 7 credits at 480P, 15 at 768P or 30 at 1080P. A 5-second take costs 35, 75 or 150 credits; at 15 seconds, 768P costs 225 and 1080P costs 450. Plans start at $19.90 a month for 1,500 credits.

Are the audio and dialogue rendered with the video?
Yes. MiniMax H3 Max generates picture, sound effects, and spoken lines in the same pass, so lip sync is native rather than dubbed on afterwards. MiniMax lists dialogue as stable in 11 languages.

How long does a MiniMax H3 Max render take?
August 2026 benchmarks timed a 5-second 768P MiniMax H3 Max clip at under 3 seconds of model time. At busy hours the queue adds time on top, so treat it as a working pace, not a guarantee.

Which resolutions can I choose on MiniMax H3 Max?
480P (default), 768P or 1080P. 768P renders at 1344×768 and 24 FPS. MiniMax's hosted base model offers 2K; this generator does not.

What can I control in an image to video shot?
The start frame is required and an optional end frame pins where the shot lands. MiniMax H3 Max keeps your still's aspect ratio; the prompt steers motion, camera, and dialogue.

Which lengths and aspect ratios does text to video support?
Whole-second lengths from 5 to 15, with 5 as the default, and six frames: 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16. 16:9 is the default.

Who owns the videos I make with MiniMax H3 Max?
You do, on a paid plan, commercial use included. Clearing third-party rights in your prompt — trademarks, likenesses, copyrighted characters — is on you.

Is MiniMax H3 Max open source?
The base model is: MiniMax published H3-Base weights under the MiniMax H3 Community License, not Apache or MIT. The MiniMax H3 Max tuned build this site runs is hosted only, no public weights.
