How to use

How to write a MiniMax H3 prompt

MiniMax rewards clear direction. Use this structure to turn your idea into a scene worth replaying.

01

Set the look

Open with format and style: live-action or paper-craft, lighting, color grade.

02

Break it into shots

Give each shot its own line with its seconds, in the order they happen.

03

Say who does what

One action per subject per shot, plus where the camera moves.

04

Pick length and render

Pick 5 to 10 seconds and 16:9, 9:16 or 1:1; every take comes back at 2K, ready to publish.

Stills in, cinema out

MiniMax H3 turns your stills into a trailer people want to play

Turn a still into a 2K trailer people replay, with no GPU or ComfyUI setup, from 395 credits. The game-parody trailer that went furthest on r/ChatGPT, with nearly eleven thousand upvotes, was built exactly this way: frames from an image model, then MiniMax H3 for the motion.

Why people pick it

MiniMax H3 prompt adherence, detail and zero setup

It does what the prompt says

In the r/StableDiffusion AMA with the H3 team, one of the most upvoted comments said its prompt adherence is impressive even when compared to image models. Write a beat, a prop and a joke, and each one lands on screen.

  • Up to 2,000 characters a prompt
  • Text to video or image to video

Long, structured prompts pay off

Creators who push MiniMax H3 hardest write in sections: style, camera, then each shot with its timing. A summer-day prompt of over 1,700 characters came back as the dreamy walk and goldfish tank it described.

  • Name the style and lens first
  • Then list shots in order

The 2K clip, without the hardware

Run locally, a commenter clocked 500 seconds for a 15-second 720p clip on an RTX 5090 with 64 GB of RAM. Here there is no card, driver or workflow to manage, and every clip renders at 2K.

  • 5, 6, 8 or 10 seconds
  • 16:9, 9:16 or 1:1

A zero-g lab with a joke hidden in it

@Alin_Reaper05 on X

A researcher, a spinning screwdriver, an expired pizza coupon and a gas giant in the window, all in one short paragraph.

Live-action zero-g interior of a derelict science lab. A female researcher in a faded jumpsuit floats through a cloud of drifting paper and a spinning screwdriver. She catches the screwdriver, then pushes off a bulkhead toward a cracked observation window. Camera gently drifts with her, slight roll. Soft practical worklights, volumetric dust, cool blue grade. Audio: quiet HVAC, paper flutter, her controlled breath. Joke: one floating paper is a pizza coupon expired in 2091. She reaches the window and sees a gas giant filling the view.

A pop-up book in four acts

@MayorKingAI on X

Style first, then each act with its seconds: mountain, cave, treasure, dragon. Swap the story and keep the structure.

Template: fill in the brackets
Pop-up book paper craft animation, 15 seconds, 16:9. Layered cut-paper 3D pop-up book style, visible paper folds and tabs, soft warm storybook lighting, hand-crafted texture, shallow depth of field on an open book. No voice, audio: gentle music box, page-turning sounds, a low rumble building to a roar.

ACT 1 (0-4s): An open storybook on a wooden table. The first paper page rises to reveal a layered cut-paper mountain landscape at dusk, tiny folded pine trees standing up. Slow push-in toward a dark cave opening in the paper mountain.

ACT 2 (4-8s): Hard cut. A page turns and pops up a cave interior — layers of paper stalactites unfold, and a pile of folded golden paper treasure rises into place, glittering. Camera drifts deeper into the cave.

ACT 3 (8-12s): Hard cut. Among the paper treasure, a massive folded paper dragon slowly unfolds and rises — wings spreading in layered paper sheets, neck extending upward, filling the frame. The rumble grows.

ACT 4 (12-15s): Hard cut. Close-up as the paper dragon's eye snaps open, glowing amber, and it lets out a roar — paper flames unfold from its jaws toward the camera. Freeze on the dragon filling the whole open book. Final roar.

An escape down a burning ship

@ItsCosmicAnts on X

A sprint under red emergency lights, Earth on fire outside, and a twist ending in bed.

Cinematic 15-second sequence: A young athletic woman with short dark hair in a fitted dark spacesuit sprints desperately down a glass-walled spaceship corridor under flashing red emergency lights, stars visible outside. She bursts into a circular observation room and collapses against a massive round panoramic window, pressing her face and hands to the glass in exhaustion. Through the window a beautiful planet violently explodes — a massive wave of fire and energy races toward the ship and smashes into the glass in a blinding flash. Hard cut: the same woman jolts awake in a dark ordinary bedroom, gasping, covered in sweat. Handheld camera, urgent pacing, intense red emergency lighting, cinematic sci-fi destruction, realistic, film grain.

Nonstop cartoon slapstick

@noorwithwifi on X

Two 3D kids, a pile of pillows and a list of every stumble, spin and crash in order.

Create a 15-second ultra-fast, adorable 3D cartoon animation of a cute boy and girl caught in nonstop chaotic slapstick comedy: they excitedly run into each other, stumble, spin, slip on a cushion, tumble into colorful pillows, dodge bouncing pillows, collide again, crash onto a couch, get launched into the air with exaggerated cartoon physics, land on a rolling rug, slide wildly across the room while grabbing furniture, then bounce into cushions and spin together before collapsing on the floor laughing. End with a pillow dropping onto the boy’s head, surprising him and making the girl laugh. Use polished cute 3D visuals, huge expressive eyes, exaggerated facial reactions, squash-and-stretch animation, vibrant colors, dynamic camera movements, whip pans, quick zooms, flying objects, cinematic lighting, and extremely rapid comedic timing. No dialogue, no pauses, no slow moments—keep continuous action and new visual gags from 0–15 seconds.

Comparisons

MiniMax H3 vs running it locally, LTX 2.5 and Kling

01

vs running it locally

A ComfyUI developer's launch post put the floor for 480p at a 12GB card and 32GB of RAM. Here you skip the hardware and get 2K from the browser.

02

vs LTX 2.5

Pick MiniMax H3 when the prompt is complex and every specific action has to land on screen; commenters praise how closely it follows the prompt.

03

vs Kling 3.0

[Kling 3.0](/video/kling-3-0) prices by resolution. MiniMax H3 prices by length alone and every clip is 2K.

04

Paired with an image model

The parody trailer with nearly eleven thousand upvotes on r/ChatGPT started as ChatGPT images, then moved in H3.

FAQ

MiniMax H3 FAQ

The questions people ask about it on Reddit, answered for how it runs on SayMaker.

None here. It runs on SayMaker's side, so there is no card to buy and every clip renders at 2K.

Locally it depends on your card: one commenter measured more than eight minutes for a short 720p clip on an RTX 5090. Here your GPU stays free and the clip comes back at 2K.

On r/StableDiffusion, users argue over step counts and samplers. On SayMaker there are none to tune: pick 5 to 10 seconds and a ratio, and spend your effort on the prompt.

In detail. Set the style first, then list each shot with its seconds and one action per subject. You have up to 2,000 characters.

That is what users praise most. In the H3 team AMA, a highly upvoted comment called its prompt adherence impressive even next to image models.

Yes. That is how the parody trailer with nearly eleven thousand upvotes on r/ChatGPT was made. Upload each image as the first frame and describe what happens next.

Yes. MiniMax ships the model under both names, and it is also listed as Hailuo 03.

Yes. Upload a still and it becomes the opening frame of a 2K clip.

395 credits for 5 seconds, 475 for 6, 630 for 8 and 790 for 10. Length is the only thing that changes it, and a technical failure is refunded.

Skip the GPU and render MiniMax H3 in 2K

Write the shots or upload the first frame and get the clip back at 2K. See the exact credits before anything runs, from 395, and a technical failure hands them straight back.
