MiniMax H3 Prompt Guide
Use this MiniMax H3 Prompt Guide to turn a rough idea into a clear video brief. Learn how to describe the subject, action, camera movement, lighting, style, sound, timing, and final frame without filling the prompt with vague or repetitive keywords.
Create with MiniMax H3Describe a video, not a still image
A strong prompt explains what changes during the clip, how the camera observes the action, what the viewer hears, and where the scene ends. Style labels only work after the shot itself is clear.
Give every reference one job
Use a source image for identity, a video for motion and camera timing, and audio for pacing or ambience. A clear hierarchy keeps identity, movement, environment, and sound from competing.
Refine one variable at a time
When a generation is close, keep the successful parts and revise only the camera, action, sound, timing, constraint, or ending. Controlled changes make the next result easier to evaluate.
MiniMax H3 Prompt Guide Formula
Subject + Action + Environment + Camera + Lighting + Style + Sound + Ending
The first four elements establish the shot. Add lighting, style, sound, and the final frame only after the primary action and camera direction are easy to understand.
Subject
Name the primary person, character, product, object, animal, or environment with a specific noun.
Action
Describe the main visible change with active verbs: walks, turns, opens, accelerates, rises, pours, transforms, or reveals.
Environment
Explain where the action happens and which background elements matter to the shot.
Camera
State the framing, viewing angle, and one primary movement. Keep short clips focused on a single camera idea.
Lighting and style
Describe light source, colour, contrast, materials, and production style after the action and camera are clear.
Sound and ending
Connect sound to visible events, then define the final composition for reveals, transformations, and narrative beats.
MiniMax H3 Prompt Guide by Workflow
Prompt Guide for Text to Video
Text-only generation needs the complete visual world. Define the subject, environment, action, camera, and ending before adding style. Keep the generation to one shot instead of compressing a complete commercial and several locations into one short clip.
A chef in a modern open kitchen places a glazed strawberry dessert on a marble counter. Start with an extreme close-up, then pull back as powdered sugar falls in slow motion. Bright editorial food lighting, realistic texture, shallow depth of field. Soft café ambience and a clear plate tap. End with the dessert centered in frame.
Prompt Guide for Image to Video
The uploaded image already communicates appearance and composition, so focus the prompt on motion, camera behaviour, preservation rules, environmental changes, and the ending. Put consistency instructions first for faces, products, labels, logos, or layouts.
Preserve the exact bottle shape, label position, cap, glass material, colours, and proportions. The bottle remains centered while the camera makes a slow clockwise orbit. Soft cyan light moves across the surface and fine mist drifts through the background. End on a clean front-facing hero shot.
Prompt Guide for First and Last Frames
Describe the transition rather than repeating both images. Explain what moves, what changes gradually, what remains aligned, and how the sequence resolves. Choose frames with compatible subjects, perspective, proportions, and style.
Hold the opening composition briefly. Daylight gradually fades as shop windows illuminate, traffic begins moving, and reflections appear across the wet street. Keep the buildings and camera position aligned. Resolve smoothly into the supplied nighttime frame without a sudden cut.
Prompt Guide for Reference to Video
Rank references and assign one role to each uploaded image, video, or audio file. Separate reference roles from the new creative direction so identity, motion, environment, and sound retain clear priorities.
Use Image 1 as the locked character reference. Preserve the face, hairstyle, age, outfit, and body proportions. Use Video 1 only for walking motion and camera pace. Place the character in a rain-covered night market. End as she stops under a blue streetlight and looks toward the camera.
Prompt Guide for Video Editing
Separate the requested change from the source footage that must remain stable. Name the target area, preservation rules, timing, and final result so success can be evaluated without ambiguity.
Replace the package in the model’s hand with the uploaded package reference. Preserve the hand position, finger movement, arm motion, lighting, lens, background, framing, shadows, and original timing. Keep the replacement aligned with the hand throughout the shot.
Camera, Motion, Sound, and Consistency Tips
Camera movement
Use plain production language: slow push-in, pullback, pan, tilt, tracking shot, follow shot, low-angle orbit, overhead view, static close-up, or handheld movement. One main movement and one optional transition is enough for most short scenes.
Motion and timing
Make movement visible and ordered: “the shot begins,” “then,” “after a brief pause,” and “the video ends.” State speed and physical relationships, for example two slow steps, a pause, then a head turn.
Sound and dialogue
Connect sound to visible events instead of requesting generic cinematic audio. Quote dialogue exactly, identify the speaker and delivery, and keep the line proportional to the chosen duration.
Consistency
For characters, preserve face, hairstyle, age, skin tone, outfit, body proportions, and accessories. For products, preserve shape, logo, label placement, materials, dimensions, colours, and packaging structure.
MiniMax H3 Prompt Guide Examples
Cinematic product ad
A silver wireless speaker rests on a dark reflective platform. The grille lights up as the camera makes a slow half-orbit. Fine dust moves through warm side light. Premium technology commercial, realistic materials, deep contrast, restrained room tone. End on the illuminated logo.
Fashion video
Preserve the model’s face, hairstyle, black coat, and body proportions. She walks through a concrete gallery while the camera tracks backward at the same speed. Soft skylight, editorial fashion film. End as she stops and turns toward the camera.
Food commercial
A chef pours glossy chocolate over a plated dessert. Start with an extreme close-up, then pull back as steam rises. Warm restaurant lighting, rich texture, shallow depth of field. Include a soft pouring sound and quiet dining-room ambience. End on the complete dish.
Fantasy environment
A ruined stone bridge crosses a valley above the clouds. A rider approaches as wind moves banners and mist flows through the arches. The camera glides forward at bridge level. Epic fantasy realism, cool dawn light, distant horns and wind. End as the rider reaches the center.
Social product hook
Keep the product shape, label, logo, and brand colours unchanged. The package drops onto a bright platform as coloured powder bursts outward. Push in quickly, then settle into a stable vertical hero shot. Add a sharp impact sound.
Character dialogue
The character sits beside a train window at night. City lights move across her face as the camera remains in a steady medium close-up. She says, “I thought we had more time,” quietly, then looks out the window. Natural carriage ambience.
MiniMax H3 Prompt Guide: Common Mistakes
- Using only style keywords instead of naming the subject and visible action.
- Describing a still image without explaining what changes during the video.
- Adding several competing camera moves to a single short scene.
- Using conflicting references without a defined hierarchy.
- Hiding product or character constraints at the end of a long prompt.
- Rewriting the complete prompt when only one variable needs adjustment.
MiniMax H3 Prompt Guide FAQ
What is the best MiniMax H3 prompt structure?
Use subject, action, environment, camera, lighting, style, sound, and ending. Include only the elements needed for the selected workflow.
How long should a MiniMax H3 prompt be?
Structured detail matters more than length. Write enough to direct the shot, then remove repeated adjectives and instructions that do not affect the result.
Should I describe an uploaded image again?
Usually no. Focus Image to Video prompts on motion, camera behaviour, preservation rules, environmental changes, and the ending.
How do I keep a character or product consistent?
Use a clear reference, avoid conflicts, and name the identity or product details that cannot change before the stylistic direction.
Can I control the camera?
Use clear camera language such as push-in, tracking shot, pan, tilt, orbit, or static close-up. Available controls depend on the current workflow and interface.
Why does my video change too much?
The prompt may contain excessive motion, conflicting references, unsuitable framing, or weak preservation rules. Simplify the shot and strengthen the highest-priority constraints.
Should I enable Prompt Optimizer?
Use it for short or incomplete prompts. Disable it where available when you need tighter control over carefully structured instructions.
