MiniMax H3 prompt guide

MiniMax H3 prompts that make the motion direction easy to review.

A useful MiniMax H3 prompt tells the model what the viewer sees first, what changes through the clip, how the camera behaves, and where the motion resolves. Start from a written scene or one approved first frame, then keep the direction focused.

MiniMax H3 prompt ingredients

These local references isolate a subject, a concrete motion, and a final image so the prompt can describe one sequence at a time. They are not presented as MiniMax H3 outputs.

Every card identifies whether it is a verified model-family example or a visual reference. Reference cards are not model benchmarks or before-and-after claims.

Subject and setting

Start with the visible subject and environment before adding motion or stylistic details.

Reference direction, not a model output

Local ImageStyle visual reference. It is not presented as a model-specific result.

Action and pace

Describe one clear movement and its speed before asking for an additional scene change.

Reference direction, not a model output

Local ImageStyle visual reference. It is not presented as a model-specific result.

End frame

State where the action resolves so the ending has a visible purpose.

A practical MiniMax H3 prompt structure

Subject and visual anchor

Name the person, object, place, or first-frame detail that must remain understandable from the opening moment.

Action and timing

Describe one movement, its pace, and the visual change that should occur over the length of the clip.

Camera and ending state

State how the camera observes the action and what the viewer should see when the clip reaches its final beat.

How to write a MiniMax H3 prompt

Use one ordered direction rather than stacking style labels. The goal is a clip that can be inspected from opening to ending.

  1. 1

    State the scene before the style

    Start with the subject, location, time of day, and visible action. Add style only after the scene is readable.

  2. 2

    Add one motion path

    Explain what moves, in which direction, and at what pace instead of listing several competing actions.

  3. 3

    Give the camera one job

    For example, keep a close view, follow the subject, slowly push in, or reveal the setting as the action changes.

  4. 4

    Define the ending and review

    Name the final visual state, generate the clip, and check whether motion, camera behavior, and important details remain usable.

MiniMax H3 prompt-writing checks

Longer is not automatically clearer
MiniMax H3 accepts up to 7,000 characters, but a focused direction with one subject and motion path is easier to evaluate.
A first frame needs a motion instruction
In image-to-video mode, the image establishes the opening composition. Use the prompt for what should change after that moment.
Review output instead of assuming fidelity
Generated motion, text, product details, and identity cues may vary. Review every result before it is used publicly.

MiniMax H3 prompts FAQ

How should I structure a MiniMax H3 prompt?
Structure a MiniMax H3 prompt as subject and setting, one action, camera behavior, timing, and an ending state. Keep the request focused so the resulting motion can be reviewed clearly.
How long can a MiniMax H3 prompt be?
The current MiniMax H3 prompt limit is 7,000 characters. Use the available space for clear visual and motion details rather than unrelated style labels.
What should an image-to-video prompt describe?
With one first-frame image attached, describe the motion, camera behavior, pacing, and ending state. Avoid spending most of the prompt restating the still image.
Can a prompt guarantee exact video details?
No. Treat generated clips as drafts and review the complete result for motion continuity, text, visible details, and anything that must be accurate.
