Prompting MiniMax H3: Precision You Can See On Screen
This MiniMax H3 prompt guide walks you through writing detailed, structured instructions for an open-weight multimodal video model that renders 5–15 second clips at 2K and 24fps with stereo audio baked in. Each MiniMax H3 prompt can run up to 7,000 characters, so you can label every reference asset, time each shot, direct camera work and sound, and hold a character's look steady from the first frame to the last.
- Tagging Every Reference by JobThe single habit that pays off most: spell out in your MiniMax H3 prompt what each uploaded image, clip, or audio file is meant to do — set a mood, cast a face, show a product, define a style, or supply a voice.
- Shot Lists With TimecodesSlice a multi-beat scene into [0-2s] and [2-4s] windows inside a single MiniMax H3 prompt, so the result moves with real narrative rhythm instead of a slow slideshow.
- Sound Design Written Into the PromptGive music, effects, and cloned voices the same detail you give to visuals in your MiniMax H3 prompt — where the sub-bass hits, when the hi-hats enter, which foley lands on which beat, and when lines are spoken.
How to Build a MiniMax H3 Prompt, Step by Step
Follow a repeatable process to shape a MiniMax H3 prompt that delivers 2K footage with sound that lines up.
Core Techniques Behind a Strong MiniMax H3 Prompt
A field-tested set of practices for your next MiniMax H3 prompt — assigning reference roles, timing shots, directing sound, blocking unwanted output, locking identity, pairing edits with constraints, using cinematic language, and treating transitions as physical events rather than named effects.
Blocking What You Don't Want
List the things to keep out of frame — 'no soft dissolves', 'no garbled text', 'no sudden scares' — and your MiniMax H3 prompt will steer clear of them.
Keeping Characters Consistent
Name the details that define a face, a product, or a location inside your MiniMax H3 prompt — hairstyle, clothing, props, typefaces — and they carry through every cut unchanged.
Pairing Edits With Constraints
When you need a change, state both what shifts and what must remain fixed in the MiniMax H3 prompt, so only that one area is regenerated.
Speaking in Cinematography Terms
Borrow the vocabulary of a camera crew — shot size, lens character, exposure, handheld shake, rack focus, wide-angle distortion, film grain — and write it straight into your MiniMax H3 prompt.
Treating Transitions as Real Motion
Instead of naming a transition, describe the motion that causes it — a whip pan, motion blur, smearing, a flicker of exposure — and your MiniMax H3 prompt reads more naturally.
Room for a Full Shot List
With up to 7,000 characters, one MiniMax H3 prompt holds the whole scene, every timed shot, the sound plan, and your constraints together.
Answers to Common MiniMax H3 Prompt Questions
Quick answers to the questions people ask most when writing a MiniMax H3 prompt for the H3 video model.
What exactly is a MiniMax H3 prompt?
A MiniMax H3 prompt is the written instruction you hand to MiniMax's open-weight multimodal video model. Strong prompts name the job of each reference, break the action into timed segments, describe sound, exclude unwanted elements, hold identities steady, and use camera language — producing 2K video with stereo audio.
Is there a length limit?
You can write up to 7,000 characters, which is plenty for a full shot list, timed beats, camera direction, audio notes, and restrictions inside a single MiniMax H3 prompt.
How should I use several reference files at once?
Give every file its own role in the MiniMax H3 prompt — 'Image 1 for mood, Image 2 for the performer, Audio 1 for the voice'. One request accepts as many as 9 images, 3 video clips, and 3 audio files.
Do I really need to describe the audio?
Absolutely. Write sound the way you write a scene in your MiniMax H3 prompt: how the music builds, when instruments come in, which foley hits land where, and where dialogue falls — that is how the built-in audio stays in step with the picture.
How can I stop characters from changing between shots?
Spell out the features that identify them — hair, clothing, props, surroundings — inside your MiniMax H3 prompt, then repeat those details across every timed segment so the look never drifts.
What are the most common prompt mistakes?
Loose pacing and unclear style. Replace slow, slideshow-like sequences with timed blocks, and add negative instructions to your MiniMax H3 prompt so unwanted elements stay out.
