PROMPTING
How to write a MiniMax H3 video prompt
A practical MiniMax H3 prompt guide for directing subject action, camera movement, timing, lighting, and visual continuity.
A useful H3 prompt reads less like a pile of style words and more like a short direction for a shot. Give the model a clear subject, a visible action, a camera decision, and enough scene context to connect them. The goal is not maximum length; it is a prompt whose instructions do not compete with one another.
Build the prompt around one readable shot
Start with who or what appears, what changes during the clip, and where it happens. “A cyclist rounds a rain-soaked corner at blue hour” gives the scene a subject, action, environment, and time. Add distinguishing details only when they matter to continuity. If two actions must happen in sequence, state the order directly instead of implying it through adjectives.
- check_circleSubject and defining details
- check_circlePrimary action and its direction
- check_circleEnvironment, time, and weather
- check_circleThe visible change from beginning to end
Direct the camera separately from the subject
Subject motion and camera motion are different instructions. Describe both: the performer may walk forward while the camera tracks backward, or a stationary product may be revealed by a slow orbit. Use one dominant move—push in, pull back, pan, tilt, orbit, handheld follow, or locked-off—before adding smaller adjustments. This reduces contradictory motion.
Use timing and restraint
Choose 5 seconds for a single beat, 10 seconds for an action with a transition, and 15 seconds when the shot needs a clearer progression. Longer duration is not a substitute for more events. Keep the action achievable within the selected clip, and remove instructions that do not affect what the viewer can see or hear.
Treat style as production direction
Describe light, lens feeling, color, texture, and pace in concrete terms: soft window light, shallow depth of field, cool shadows, restrained grain, or a measured dolly move. When using a start frame or references, let those assets carry identity and composition while the prompt concentrates on action, camera, and change.
Prompt checklist
- checkOne primary subject and action
- checkOne dominant camera move
- checkA scene that fits the chosen duration
- checkConcrete lighting and visual direction
- checkNo conflicting actions or camera instructions
