How to prompt MiniMax H3 Max
H3 Max Studio · last updated 3 September 2026
A MiniMax H3 Max prompt is four parts in one box: subject, camera, light, and sound. Put spoken lines in quotes. Match the number of beats to the duration you buy.
The four-part formula
Subject and action first. Then camera (dolly, track, pan, crane, handheld, or locked). Then light and style. Then sound: foley, room tone, music, and any spoken line. H3 Max reads them as one shot, not four separate jobs.
Product spot
Macro shot of a glass perfume bottle on wet black slate. A warm spotlight swings across the label and catches a gold mist. Sound: a single glass tap, then a short aerosol hiss and a low studio bed.
15-second beats
0-5s: wide crane down to a vintage coupe on a dusk beach. 5-10s: the driver checks the mirror. 10-15s: the car pulls away along the wet sand. Sound: surf, a door latch, then a rising engine.
Dialogue close-up
Cinematic close-up of a detective under a fogged street lamp. He says, "The ledger was in the coat the whole time." Sound: slow footsteps on wet stone and one distant bell.
Expansion, seed, and safety
Balanced expansion is the default. Quality spends more prompt rewriting. A fixed seed helps you compare one wording change. The safety checker stays on unless you turn it off in More options.
FAQ
Should I write a shot list or a paragraph?
A short paragraph with timed beats works better than a bullet dump. Keep it in one field.
Do I need a negative prompt?
No. Official MiniMax H3 Max inputs on fal are the prompt plus the mode fields. Describe what you want, including silence if you need a quiet room.
Where do I try these prompts?
Paste them into the studio on the home page or workspace. A 5-second 768p draft is 25 credits.
