Inside the MiniMax H3 prompt: Structure, Timing, Sound
This MiniMax H3 prompt handbook walks you through a general-purpose, open-weight multimodal video model that returns 5-15 second clips in 2K at 24fps, complete with stereo audio generated on the fly. A single prompt can run up to 7,000 characters — room enough to label every reference asset, map out beats by timestamp, specify lens and lighting choices, describe the soundtrack, and keep a character looking the same from first frame to last, all inside one request.
- Tag Every Reference with a JobThe habit that pays off most: spell out what each uploaded image, clip, or audio file is meant to do — set the mood, cast the talent, show the product, define a style, or supply a voice.
- Beats Mapped to TimestampsSlice a multi-beat scene into [0-2s] and [2-4s] segments within one MiniMax H3 prompt, so the result moves with real narrative rhythm instead of a slideshow feel.
- Sound Cues Written Like a ScoreGive the soundtrack the same attention as the picture in your MiniMax H3 prompt — note the music's build, where the hi-hats land, which foley hits sync to action, and when each line of dialogue arrives.
Five Steps to a Polished MiniMax H3 prompt
Follow five moves to shape a MiniMax H3 prompt that returns 2K footage with audio locked to picture.
Core Techniques for a MiniMax H3 prompt
A roundup of the techniques that separate a usable MiniMax H3 prompt from a great one — reference roles, timestamped beats, audio notes, exclusions, identity locks, edit limits, film language, and event-driven transitions.
Exclusions That Steer the Model
Say what you don't want as clearly as what you do: ban soft dissolves, scrambled text, or sudden scares inside your MiniMax H3 prompt, and the model is far less likely to drift there.
Locking Look and Detail
Keep people, products, and places looking the same shot to shot by naming the details that matter in your MiniMax H3 prompt — hairstyle, clothing, props, even typefaces.
Targeted Edits, Not Full Rebuilds
When you only want one thing changed, state the swap and the parts that must not move; a well-scoped MiniMax H3 prompt edits a corner of the frame instead of rebuilding the whole clip.
Language Borrowed from Cinematography
Borrow the vocabulary of a camera crew in your MiniMax H3 prompt: frame size, lens character, exposure, and texture such as handheld sway, rack focus, wide-angle stretch, or visible grain.
Cuts Described as Motion
Instead of naming an effect, write the movement that causes it — a fast whip, smeared highlights, a flicker of exposure — and the transition lands more naturally in a MiniMax H3 prompt.
Room for the Whole Plan
With roughly 7,000 characters to spend, one MiniMax H3 prompt can hold the full scene, every timed shot, the audio plan, and all of your constraints together.
MiniMax H3 prompt — FAQ
Answers to the questions people ask most when they start writing a MiniMax H3 prompt.
What exactly is the MiniMax H3 prompt guide?
It is a collection of prompting practices for MiniMax's open-weight multimodal video model, covering how to label reference assets, time your beats, direct audio, add exclusions, lock identity, and describe shots cinematically — all aimed at 2K output with native stereo sound.
How many characters can one prompt hold?
Roughly 7,000. That is enough room in a single MiniMax H3 prompt for a complete shot list, timestamped beats, camera directions, an audio plan, and any constraints you want honored.
What's the best way to use several reference files?
Give each file a distinct purpose inside your MiniMax H3 prompt — one image for mood, another for the performer, an audio clip for the voice — and you can supply up to 9 images, 3 video clips, and 3 audio files in one request.
Do I really need to write about sound?
Yes. Treat audio as a scene of its own in the MiniMax H3 prompt: describe the music's structure, when instruments enter, which foley hits matter, and how dialogue is delivered, so the generated sound matches your edit.
How can I keep a character looking the same throughout?
List the features that define them — hair, wardrobe, props, surroundings — inside the MiniMax H3 prompt, and repeat those anchors at every timed beat so cuts don't break continuity.
What tends to ruin a prompt?
Loose pacing and vague styling. Replace slideshow-style sequences with timestamped blocks, and add exclusions to the MiniMax H3 prompt so unwanted looks or artifacts stay out.
