Inside the MiniMax H3 Prompt Format
This MiniMax H3 prompt format is built for an open-weight, general-purpose multimodal video model that renders 5-15 second clips at 2K, 24fps, complete with native stereo audio. One request can hold up to 7,000 characters, so you can label every reference asset, block scenes out by timestamp, direct camera movement and sound, and keep identities steady across shots.
- Give Every Reference a JobThe habit that pays off most in any MiniMax H3 prompt: spell out what each image, clip, or audio file is meant to do — mood, talent, product, style, or voice.
- Scene Beats on a TimelineSplit a multi-beat sequence into [0-2s], [2-4s] blocks inside one MiniMax H3 prompt so pacing feels like a film instead of a slideshow.
- Sound Cues with Director-Level DetailIn the MiniMax H3 prompt, describe music structure, effects, and voice cloning as carefully as visuals — sub-bass, hi-hats, foley, and when lines land.
Writing a MiniMax H3 Prompt, Step by Step
Build a clean, professional MiniMax H3 prompt in a few steps for 2K video with synchronized audio.
MiniMax H3 Prompt Techniques That Matter
Field-tested habits from the MiniMax H3 prompt playbook — negative directions, identity locking, edit constraints, cinematic language, event-based transitions, and full-length control — that keep AI video output precise and professional.
Negative Directions
Tell the model what you don't want — 'No soft dissolves', 'no garbled characters', 'no jump scares' — and your MiniMax H3 prompt steers clear of those results.
Identity Locking Across Cuts
List the defining details — hair, wardrobe, props, typography — in your MiniMax H3 prompt so characters, products, and sets stay recognizable through every edit.
Edits Paired with Constraints
For editing work, every replacement in the MiniMax H3 prompt comes with a note on what must remain unchanged, so changes stay local instead of regenerating the whole frame.
Camera Language Borrowed from Film
Reach for shot scale, lens behavior, exposure, and film texture — handheld shake, rack focus, wide-angle distortion, grain — and write them straight into the MiniMax H3 prompt.
Transitions as Physical Motion
Rather than naming an effect, describe the movement itself — a whip pan, motion blur, optical smear, exposure flicker — which reads more reliably in a MiniMax H3 prompt.
Up to 7,000 Characters
One MiniMax H3 prompt can carry an entire shot list plus sound design: full scene, timed beats, audio, and constraints in a single pass.
MiniMax H3 Prompt: Common Questions
Straight answers about prompt length, reference assets, audio direction, and character consistency when writing for the MiniMax H3 video model.
What exactly is the MiniMax H3 prompt guide?
A collection of proven practices for writing prompts for MiniMax's open-weight multimodal video model. It covers how to label reference assets, timecode your shots, direct audio, add negative directions, lock identity, and use cinematic vocabulary — all toward 2K video with native stereo audio.
How much text can one prompt hold?
Roughly 7,000 characters, which is enough for a complete shot list with timed beats, camera instructions, audio design, and constraints inside a single MiniMax H3 prompt.
Can I use several reference files at once?
Yes. Give each one a clear role in the MiniMax H3 prompt — 'Use Image 1 for mood, Image 2 for talent, Audio 1 for voice' — with support for as many as 9 images, 3 video clips, and 3 audio files per request.
Do I need to describe the soundtrack?
Absolutely — treat audio as another scene in your MiniMax H3 prompt. Note the music structure, when instruments enter, foley details, and dialogue so the generated stereo sound lines up with the edit.
How do I stop characters from changing?
Spell out the features that define them — hair, wardrobe, props, set details — inside the MiniMax H3 prompt, then carry those same notes through every timed beat and cut.
What weakens a prompt?
Loose pacing and unwanted styles. Replace slideshow-style sequences with timecoded blocks, and add negative directions to your MiniMax H3 prompt to keep out anything you don't want.
