Question 1

What is MiniMax H3 Max?

Accepted Answer

MiniMax H3 Max is a post-trained version of MiniMax H3, built by fal rather than by MiniMax. fal took H3's open weights, retrained them on their own data for stronger prompt adherence and better aesthetics, then served the result on their own hardware. It returns five to fifteen second clips at up to 768p with native stereo audio.

Question 2

Is MiniMax H3 Max made by MiniMax?

Accepted Answer

No, and the name misleads. MiniMax built and open-sourced H3. fal post-trained those weights into the variant called H3 Max and hosts it exclusively. MiniMax has never announced a model by that name, so treat H3 Max as fal's tuned edition of an open MiniMax model, not a MiniMax release or an official H3 tier.

Question 3

How is MiniMax H3 Max different from MiniMax H3?

Accepted Answer

Three ways. H3 Max is post-trained for prompt adherence and aesthetics on top of the base weights. It is tuned for speed rather than maximum resolution, stopping at 768p where H3 reaches 2K. And it covers text to video and image to video only, while H3 adds reference generation from mixed images, clips, and audio.

Question 4

How fast is MiniMax H3 Max?

Accepted Answer

fal targets sub-three-second text to video on a five-second 768p clip, against the 30 seconds to several minutes video normally takes. It runs on fal's multi-node inference engine, several machines working on one request together. Keep prompt expansion on balanced: the slower quality setting adds about thirty seconds and gives that speed advantage straight back.

Question 5

Does MiniMax H3 Max do image to video as well as text to video?

Accepted Answer

Both are live. Text to video turns a written scene into a clip. Image to video animates a still you supply, and the same mode accepts a first and last frame, so the motion runs between two images you picked. A third mode, reference to video, holding a character consistent, is announced as coming later.

Question 6

Why does MiniMax H3 Max stop at 768p?

Accepted Answer

Because 768p is what the open weights generate. H3 is a three-part system: a preprocessor that interprets the brief, a base model that renders at 768p, and a separate stage that regenerates it at 2K. MiniMax open-sourced only the base model, so anything post-trained from those weights has no 2K stage to hand off to.

Question 7

Does MiniMax H3 Max generate sound?

Accepted Answer

Yes. The underlying model predicts video and audio together rather than scoring the clip afterwards, so a generation returns stereo sound with the picture. That makes audio worth writing into the brief: name the effects you want, the room tone, and the exact moment a cue should land, rather than arranging all of it later.

Question 8

Can I use MiniMax H3 Max on Morphic?

Accepted Answer

Yes. Pick MiniMax H3 Max in the model picker, switch the prompt bar to video, and write the shot as a brief covering subject, action, camera, light, and the sound you want. Takes land on the Canvas, so you can run the same brief through another model and compare them side by side before choosing.
