Which MiniMax H3 Max mode to use
MiniMax H3 Max has 2 modes. Pick by what you already have.
| Mode | You give it | Best for | From |
|---|---|---|---|
| Text → Video | A prompt | Ideas from scratch: scenes, b-roll, concepts and storyboards. | $0.0396/s |
| Image → Video | A first frame, optionally a last frame, and a prompt | Bringing a picture you already have to life: a product shot, a character, an artwork. With a last frame: transitions and loops. | $0.0396/s |
Step by step
How to use MiniMax H3 Max in 6 steps
- 1
Open MiniMax H3 Max in the Studio
Open the Studio (it opens with MiniMax H3 Max selected), or choose the Video tab and pick MiniMax H3 Max in the model menu. Sign in with Google or your email; you pay per generation from prepaid credits.
- 2
Choose what to make
- Text → Video — a prompt.
- Image → Video — a first frame, optionally a last frame, and a prompt. Add it under “First frame” (and “Last frame” for a transition).
- 3
Write the prompt
One shot per prompt works best. Cover these, in plain sentences:
- Subject. Who or what is on screen, with the details that must stay consistent: age, clothing, materials, colours.
- Action. One clear action in the present tense. For clips up to 15 s, describe a short sequence of beats.
- Camera. Shot size and movement: close-up, wide, dolly-in, orbit, handheld, drone.
- Scene and light. Location, time of day, and where the light comes from.
- Style. Lens, film look, colour grade or animation style.

Set the options
The settings sit under the prompt; rarely needed ones are behind ⋯. What each does — and to the price — is in the table below.
- 5
Generate
The exact price is shown before you run: press Generate (or ⌘/Ctrl + Enter). The amount is held from your balance and refunded in full if the generation fails.

Download and iterate
Results appear above the prompt; download them from there. Change one thing per try — the prompt, the camera move or a setting — so you know what helped. Compare runs the same prompt on several models side by side, and Code shows the same request for the API.

Common MiniMax H3 Max mistakes
Drafting at 768P
Every try at 768P costs 1.5× one at 480P. Settle the composition and motion at 480P, then render the keeper at the resolution you deliver.
Expecting one long take
One generation is up to 15 seconds (5–15 s). Plan longer pieces as several shots, and keep the subject consistent with the same first frame in each.
Several actions in one prompt
Give each clip one clear action and one camera move. A list of events in one prompt usually gets merged or skipped.
Describing what you don't want
Prompts work better when they describe what should be on screen. "No blur" or "no extra fingers" can pull the result towards the very thing you name.
