How it works
From video notes to an editable brief
1. Describe your reference
Use the homepage analyzer or your own observations. Capture the subject, visible action, camera movement, and what you want to preserve or change.
2. Draft a minimax-h3 prompt
Paste a concise text brief into the tool. Keep important reference roles and desired changes explicit; the generated cards are editable planning text, not a finished video.
3. Review and use elsewhere
Check the minimax-h3 draft against your source. Supply actual reference assets in your selected H3 interface and verify its supported settings before rendering.
Plan a clearer minimax-h3 brief
Minimax-h3 and minimaxh3: one video-to-prompt workflow
This H3 prompt guide turns observations from an existing clip into a practical creative brief. The spellings minimax-h3, minimaxh3, and MiniMax H3 refer to the same model intent on this page, not three different generators. Start with a video you can use, identify the visual decisions worth keeping, and describe the changes you want. The output here is editable text: you still choose an appropriate H3 interface, supply any required reference assets there, and inspect the resulting video yourself. MiniMax describes H3 as a multimodal generation model that can work with text, images, video, and audio context. That model capability is different from what this website provides. Our minimax-h3 helper accepts written notes and returns prompt cards; it does not upload your references to MiniMax, run its video model, or distribute its weights. Use the homepage video analyzer first when you need help describing a source clip, then bring the relevant observations back here.
Build a H3 brief from visible evidence
Watch the reference once for the overall action and again for specific changes. Record the opening composition, the main subject, the direction of movement, and what the final frame reveals. Separate camera motion from subject motion: a person approaching a fixed camera is not the same instruction as a camera moving toward a stationary person. For a useful H3 input, identify which of those relationships matters rather than writing only that the scene feels cinematic. Keep observations separate from invention. If a jacket looks dark but the fabric is unclear, do not present leather as a recovered fact. If a cut hides how a product was placed on the table, describe the visible placement rather than inventing the missing action. A minimax-h3 brief can include creative additions, but label them as requested changes. This distinction makes it easier to review the generated prompt against both the source and your intended result.
Define the role of each H3 reference
Before preparing a multimodal job, make a small reference inventory. For every asset, write what it contributes: character appearance, product shape, camera timing, setting, or audible material. Decide what should remain unchanged and what may vary. For example, a source clip might provide the movement of a hand, while a separate photograph provides the new product. Those are different roles, and a H3 instruction should not accidentally ask the model to copy every visible detail of both. The official H3 full-reference guide distinguishes reusable subjects from picture, video, and audio references. Its structured format includes definitions, a summary, retention analysis, a chronological description, and sound sections. This page does not claim that its cards implement that entire schema. Treat the cards as planning material, then adapt them to the reference format supported by your chosen interface. Never mention an attached reference in your final minimax-h3 request unless you actually supplied that asset there.
Write H3 motion in a readable sequence
Build the action as a short progression with a clear starting state and end state. Instead of asking for a bottle that rotates dramatically, describe the bottle standing upright, turning slowly until its front label faces the camera, and stopping without leaving the tabletop. Add the camera movement in a separate sentence. This keeps the H3 brief understandable even when another person needs to approve it before a generation run. Use one dominant action per shot when you are establishing a baseline. A continuous move, a sudden cut, and a reverse angle are different editing choices; combining them casually makes the result harder to evaluate. If multiple shots are essential, state where each begins and what should carry across the cut, including wardrobe, object placement, and light direction. Review the generated minimax-h3 cards for contradictions such as a locked camera and an orbit requested in the same moment. Remove competing instructions rather than adding more adjectives.
Practical minimax-h3 prompt decisions
Plan sound without pretending the clip was transcribed
An observed video may suggest useful audio direction, but a visual description is not an audio transcript. Only include exact dialogue when you know what was said and intend to use it. If you cannot hear a line clearly, leave it unspecified or replace it with an explicitly new line. For H3 planning, distinguish sounds physically happening in the scene from background music that only the audience hears. That separation helps prevent a passing sound effect from turning into a continuous soundtrack. The official base prompt guide uses shot descriptions and explicit conventions for speakers and dialogue. You can consult it when adapting your draft for an H3 workflow that accepts those conventions. The sound field in our prompt cards is a creative note, not proof of native audio generation or speech accuracy. After rendering in your selected provider, check actual timing, pronunciation, and whether the audible result matches the action; a detailed minimax-h3 prompt still needs human review.
A H3 example: adapt a product reveal
Example input: My reference shows a ceramic cup on a pale wooden table. A hand enters from the right and turns the handle toward the viewer. Soft window light comes from the left. Keep the single continuous shot and gentle pace, but use my blue cup reference rather than the white cup in the source. Keep the background simple. Finish with the hand out of frame. Add a quiet ceramic contact sound, with no dialogue. This gives the H3 helper an observable scene plus a clearly marked change.
Review the example before rendering
After generating, check that the draft does not invent a logo, add steam that was never requested, or turn the cup into a different material. Keep any reference image requirements alongside the prompt so they are not lost when you copy the text. For a second H3 experiment, change only the framing from medium to close, leaving the action and light unchanged. You can then judge whether the framing helped without confusing that decision with an entirely new scene.
A repeatable minimax-h3 workflow
Iterate on H3 prompts with a small checklist
The first draft is a starting point, not an assurance of model obedience. Compare the prompt against your notes before spending time rendering elsewhere. Confirm the subject, requested changes, movement direction, shot order, lighting, and desired finish. Delete repeated style words if they do not clarify a visible decision. If the H3 output adds a duration you did not choose, adjust it to the actual options in your target interface rather than treating the generated number as a vendor specification.
Keep the experiment reproducible
Keep a compact record of each attempt: the written prompt, references used, provider model selection, available settings, and the visible issue you want to correct. Revise one issue at a time. If the camera moves too much, simplify its instruction before changing the subject and lighting too. This approach cannot guarantee a successful render, but it gives a H3 iteration a testable purpose and makes it easier to keep the improvements that actually matter to your clip.
Use the prompt tool without confusing access or ownership
This independent H3 page helps prepare prompts; it is not a MiniMax account portal and does not provide video-generation credits. Free prompt-tool access should not be read as free or unlimited H3 rendering. The video provider controls its own availability, limits, output settings, and terms. Check those settings at the time you render rather than relying on a duration or resolution casually included in a creative draft.
Check the finished result
Use source footage and reference assets you are entitled to use. When reviewing a H3 adaptation for publication, check visible names, product text, faces, and any recognizable branding instead of assuming they transferred correctly. Keep a human approval step for claims shown on screen. The useful end product of this workflow is a clearer, reviewable brief with documented references, not a promise of identical footage. If you searched for minimaxh3 to understand prompting rather than download files, this is the same focused workflow.
