MiniMax H3 Prompt Guide for Better Video Briefs

Turn an idea into a shot-by-shot video brief. Choose your workflow, define visible action, direct camera and sound, then copy a template built for MiniMax H3.

Build the prompt in five passes

Work from intent to constraints. This order makes conflicts easier to spot and revisions easier to evaluate.

01

Choose one job

Define the clip's single purpose: a product reveal, dialogue beat, motion study, transition, edit, or narrative payoff.

02

Lock the stable truths

Name the identity, product geometry, wardrobe, logo, location, or layout that must not drift during motion.

03

Write visible change

Use active verbs in time order. Describe what the viewer can see instead of internal thoughts or abstract mood alone.

04

Direct capture and sound

Specify framing, camera movement, speed, lighting, dialogue, effects, ambience, and non-diegetic music.

05

Define the ending

State where the subject, camera, and key object finish. A clear landing point gives the clip a readable payoff.

The MiniMax H3 prompt formula

Write a video brief, not a still-image caption. Tell the model what changes, when it changes, what the camera observes, and what the viewer hears.

01

Reference roles

Assign one clear job to every image, video, or audio file.

02

Timed visual beats

Describe a starting state, visible actions, cuts, and the ending state.

03

Camera and look

Set framing, movement, speed, lighting, texture, and capture style.

04

Dialogue and sound

Name the speaker, exact line, effects, ambience, and music direction.

05

Constraints

State what must remain fixed and what should not appear.

Reference roles + timeline of visible action + camera and visual language + dialogue and sound + preservation rules + final frame

Copy-ready prompts for each workflow

Choose the mode that matches your inputs. Image-to-video frame roles and reference-to-video roles cannot be mixed in the same V2 API request.

TEXT TO VIDEO TEMPLATE

Build the complete audiovisual scene from text

Text-to-video needs the whole world: subject, setting, visible action, camera, lighting, sound, and ending. Keep a short clip focused on one central idea.

integrated_multimodal_description:
[Shot 1] A [specific subject] in [specific environment]. [Starting state]. The subject [visible action in chronological order]. The camera begins with [framing] and [camera movement + speed]. [Lighting, material, and capture style]. End with [final composition or resolved action].

overall_soundscape: [ambient sound], [event-linked sound effects], and [dialogue with named speaker if needed].

non_diegetic_music: [instrumentation, mood, tempo, and when the cue changes—or state no music].

API settingFor text-only generation, choose a concrete ratio such as 16:9 or 9:16. The V2 API does not allow adaptive for T2V.

MiniMax H3 prompt examples

These templates show the level of specificity to aim for. The media illustrates relevant MiniMax H3 use cases; generation results can vary with references, settings, and provider implementation.

TEXT TO VIDEO

Rain-lit courier dialogue

A compact narrative beat with a clear path, one spoken line, environmental motion, and a defined final frame.

A courier in a dark green coat crosses a crowded night market in light rain. The camera tracks backward at chest height as she moves through steam and red lantern reflections. At 00:04.500, she stops under an awning, turns toward camera, and says in a low, urgent voice: "We leave before dawn." End on a tight close-up as a scooter passes behind her. overall_soundscape: rain, distant scooters, crowd murmur, and fabric movement. non_diegetic_music: restrained low strings, fading under the dialogue.

IMAGE TO VIDEO

Precision product orbit

An image-to-video template that prioritizes product geometry, readable branding, controlled lighting, and a clean landing frame.

Preserve the exact bottle shape, label position, cap, glass material, colors, typography, and proportions from Picture 1. The bottle remains centered while the camera makes a slow clockwise orbit at label height. A narrow cyan light travels across the glass as fine mist drifts behind it. Keep the label sharp and facing the camera whenever visible. End on a clean front-facing hero shot. Sound: a soft glass tap and restrained room tone. No dialogue.

REFERENCE TO VIDEO

Character and motion transfer

A multimodal brief that separates identity, movement, environment, and voice so each reference has a distinct purpose.

Image 1 fixes the lead character's face, black bob haircut, silver jacket, and red gloves. Image 2 fixes the rainy rooftop environment and blue-magenta lighting. Video 1 supplies the running motion and handheld camera rhythm only. Audio 1 supplies the lead's voice timbre. Create a 9:16 chase beat. She runs toward the roof edge, looks back once, and says: "Keep the signal alive." Preserve her identity and wardrobe throughout. Do not copy the performer or location from Video 1.

TEXT TO VIDEO

Interface product reveal

A motion-design prompt with explicit text behavior, transition order, interaction states, and a ban on garbled interface copy.

Create a 16:9 product interface demo on a dark graphite background. The headline "DESIGN IN MOTION" slides down and holds for two seconds. A mobile dashboard enters from the right, then three data panels expand in sequence as the cursor selects "Preview." Keep all requested English text clean and legible. Use crisp mask reveals and hard cuts, not liquid morphs. Add subtle interface clicks and a low electronic pulse. End with the dashboard centered and the headline unchanged.

Direct motion, camera, dialogue, and sound

Specific direction beats adjective stacks. Use one primary camera idea, connect sound to visible events, and keep the action possible within the selected duration.

TIMELINE

Start with state changes

For multi-beat clips, state what happens first, what changes, and where the scene ends. Introduce later shots with a clear timestamp or transition.

[Shot 2] At 00:04.500, cut to a tight close-up as the bridge shakes.

CAMERA

Combine type, speed, and amplitude

"Camera moves" is vague. Name the framing and one controlled motion: a slow low-angle dolly, a fast handheld push, or a wide orbit with restrained speed.

Begin in a medium profile, then make a slow clockwise orbit at shoulder height.

DIALOGUE

Bind every line to a speaker

Name who speaks, how the voice sounds, and whether the speaker is on screen. Keep lines short enough to fit the scene without rushing the action.

The mechanic, on screen, whispers: "Let's see if you remember the sky."

SOUND

Separate the scene from the score

Use the soundscape for dialogue, footsteps, impacts, and room tone. Use non-diegetic music for score, instrumentation, tempo, and cue changes.

overall_soundscape: light rain and distant traffic. non_diegetic_music: no music.

Give the camera one clear job

Pair a shot size with one primary movement, then add speed or direction only when it changes the result you want. This gives the model clearer staging than a loose request to “make it cinematic.”

Shot Types

A useful default is to name the shot size before the action.

  • Wide shot
  • Medium shot
  • Close-up
  • Extreme close-up
  • Over-the-shoulder shot
  • POV shot
  • Aerial shot
  • Dutch angle
  • Two-shot
  • Insert shot

Camera Movement

Use familiar cinematography terms, then clarify pace and direction.

Slow push in
Camera moves toward subject
Tracking shot
Camera moves alongside moving subject
Crane up
Camera rises vertically, reveals context
Crane down
Camera descends, closes in on subject
Orbit
Camera circles subject (specify clockwise/counterclockwise)
Handheld
Intentional shake, naturalistic, documentary feel
Static locked
No movement, deliberate stillness
Whip pan
Fast horizontal snap between subjects
Rack focus
Shifts focus between foreground and background
Dolly zoom
Zoom + physical move, creates vertigo effect
Extreme close-up of coffee being poured into a white ceramic cup on a marble
countertop, morning light through frosted glass. Camera slowly orbits
counterclockwise while rack focusing from steam to the cup surface. Rich coffee
pour sounds, quiet kitchen ambience. Warm golden color grade. 2K.

Give every reference one job

Reference-to-video works best when each file controls a different part of the result. State the role in plain language before the timeline.

InputUseful rolePrompt languageDocumented V2 API limit
Reference imageIdentity, product shape, wardrobe, location, layout, or art direction"Image 1 fixes the lead's face and wardrobe."Up to 9; use reference_image

Make vague prompts shootable

Each rewrite turns a general idea into visible action, a camera decision, and an ending the clip can plausibly reach.

01

Leading with adjectives instead of shot type

Weak
Beautiful cinematic video of a woman walking.
Strong
Medium tracking shot of a woman in a cream linen dress walking along a coastal cliff path at golden hour. Camera tracks alongside at walking pace. 2K.
02

No camera movement specified

Weak
Close-up of coffee being poured. Morning light. Warm.
Strong
Extreme close-up of espresso being poured into a white ceramic cup on a marble surface, morning window light. Camera holds static then slowly pushes in at 5s. Audio: rich pour sounds, quiet kitchen ambience. 2K.
03

Missing audio direction

Weak
A woman running through a forest at dawn. 2K.
Strong
Medium tracking shot of a woman trail running through a dense green forest at dawn, mist rising. Camera tracks alongside at running pace, handheld energy. Audio: rhythmic footsteps on earth, birdsong, gentle instrumental score rising — no dialogue. 2K.
04

Describing transitions instead of shots

Weak
Shot 1: Wide shot of city. Cut to Shot 2: Medium shot of character entering. Then close-up of their face.
Strong
Shot 1 [0–4s]: Wide — city skyline at dusk.
Shot 2 [4–10s]: Medium — character enters a building lobby.
Shot 3 [10–15s]: Close-up — face in the elevator reflection, determined expression.
05

The prompt describes appearance but no visible change

Weak
A futuristic city at night with neon signs and rain.
Strong
Wide establishing shot of a futuristic city at night. Rain begins to fall, neon signs flicker on in sequence, and a hovercar descends through the frame. Camera slowly cranes up to reveal the full skyline. Audio: rain, distant traffic, electronic hum. 2K.
06

Vague reference roles

Weak
Use Image 1, Video 1, and Audio 1 to make a video.
Strong
Image 1 fixes the lead character's face, black bob haircut, and silver jacket. Video 1 supplies the running motion and handheld camera rhythm only. Audio 1 supplies the lead's voice timbre. Create a chase scene through a rain-lit alley. Preserve her identity throughout.

MiniMax H3 prompt questions

What is the best MiniMax H3 prompt structure?

Start with reference roles, then describe timed visual beats, camera direction, sound, constraints, and the final frame. Use active verbs and visible changes instead of a list of style words.

How long can a MiniMax H3 prompt be?

The MiniMax video generation V2 API documents a maximum of 7,000 characters for each required text prompt. Shorter prompts can work when the shot is simple.

What video lengths and resolutions are supported?

The V2 API lists integer durations from 4 through 15 seconds and resolution options of 768P and 2K. Available ratio behavior depends on the workflow.

Can MiniMax H3 generate dialogue and sound?

Yes. MiniMax H3 produces audiovisual output and accepts audio references for reference-to-video. Direct the speaker, exact line, effects, room tone, and music separately.

Can I mix first-frame images with reference media?

No. The official V2 API describes image-to-video roles and reference-to-video roles as mutually exclusive within one request.

How many reference files can I use?

The V2 API documents up to nine reference images, three reference videos, and three reference audio files. File formats, dimensions, sizes, durations, and the total request size also apply.

Does this guide require ComfyUI or a local GPU?

No. You can use these templates with a compatible hosted MiniMax H3 interface. Local ComfyUI workflows may require separate software, model files, and suitable hardware.

How do I stop MiniMax H3 from adding music?

Describe the intended room tone and effects in overall_soundscape, then state non_diegetic_music: no music. Results can still vary, so confirm the output before production use.

Can I use MiniMax H3 output commercially?

Commercial use depends on the license and terms of the service you use. Review current provider terms and confirm that you hold the necessary rights to every uploaded image, video, voice, and audio reference.

How are generation credits calculated?

Credit pricing is provider-specific and can change. Check the current MiniMax H3 pricing page before generating; this guide does not publish an unverified credit rate.

Move from the core guide into a narrower task when you need more examples, setup details, or pricing context.
