MiniMax H3 Prompts: How to Get Smooth, Expressive Motion

Pexo describes H3 as taking text, image, video and sound context for audiovisual output. That makes reference roles worth stating explicitly in a brief: which image defines appearance, which clip suggests motion and which rights-cleared sound supplies ambience. These are prompt-design choices based on Pexo's published description, not measured performance claims. Check which inputs your current session accepts before uploading. If sound is the main source, compare Pexo's audio-to-video workflow with this multi-input brief.

For the presenter example below, use the approved product photo for the mug's shape, the consented presenter reference for appearance and an authorized sound reference only if that input is available. Ask for the lid click at the visible opening action. Review both its timing and the mug hardware in the preview; do not assume the model preserved either automatically.

Developer source. MiniMax's H3 announcement describes multimodal context and audiovisual output (checked 2026-10-20). This supports the published capability summary above; it does not verify which input types are enabled in a Pexo session.

Small expression change

Show an original adult character listening in a quiet cafe. Begin with a neutral expression, then a small smile as a friend enters. Keep clothing, face and seat position consistent. Use low room ambience and no dialogue.

Product presenter

Use the supplied product and approved presenter references. The presenter picks up the real travel mug, opens its actual lid once and sets it down. Keep the mug hardware and presenter identity consistent. Use natural hand and table sounds; leave narration for an approved script.

The review goals are expression continuity, believable hand movement and sound placement. No clips were generated for this page.

Motion detail

An original cyclist rounds one gentle bend on a coastal road. Track at riding speed, then cut to a wheel close-up before returning to the same direction of travel. Keep jacket, bicycle and weather consistent. Use wind and tire sound.

Brand scene

Use the approved bakery storefront and pastry photos. Show a hand placing one loaf on the real counter, then a short reaction shot of an original staff member. Finish on the supplied logo. Keep all visible signage accurate and use quiet shop ambience.

Check whether the same objects and direction survive each cut. These prompts do not represent H3 test results.

Pexo lists several video models. To compare them fairly, hold the prompt, assets and desired shot length constant, then record what the account actually routed and produced. An audio-led task may call for different review criteria than a silent product close-up. Without real paired runs, this page does not rank H3 against another model.

If you need a still product image, choose an image workflow. If exact spoken copy is the central deliverable, plan for script approval and manual audio review, regardless of the video model. If a different video model is available, choose based on the preview's fidelity to your specific brief.

Start at Pexo's H3 model page or create directory. Supply the brief and rights-cleared references; check what model and controls your account actually uses. Review motion, sound, captions, likeness consent and claims before treating a draft as final.
