What

MiniMax H3 is an AI video generator that produces 5‑ to 15‑second clips at up to 2K resolution and 24 fps. It targets content creators, advertising teams, and production studios that need quick, production‑ready video with native stereo audio. The tool combines text prompts with images, video, and sound references in a single workflow.

Features

Text‑to‑video generation – Create a full shot from a written brief, including subject, action, camera movement, lighting, style, and sound.
Native stereo audio – The model outputs audio that matches the visual timing, eliminating a separate post‑production step.
Reference‑led workflow – Upload up to nine images, one video clip, and one audio clip to lock character appearance, product details, motion, and ambience.
First‑and‑last‑frame control – Provide opening and closing images to guide transitions, useful for product reveals and storyboard animation.
Multiple aspect ratios – Choose from 21:9 to 9:16, enabling use in cinematic, web, social, and mobile formats.

Helpful Tips

Keep prompts concise and focused on changes that occur during the clip; avoid long keyword lists.
Use first‑and‑last‑frame when the final composition must be exact, such as a product transformation or a storyboard frame.
Add a reference image to lock a character or product’s appearance; add a video clip to convey motion or camera language.
Verify generated text and audio for brand consistency; keep wording short and check the frame before publishing.

OpenClaw Skills

MiniMax H3 could be incorporated into OpenClaw workflows that automate end‑to‑end video production. An OpenClaw agent might accept a storyboard or script, generate a MiniMax H3 clip, then apply OpenClaw’s subtitle, branding, or asset‑assembly tools to produce a ready‑to‑publish asset. This combination would streamline short‑form ad creation, product demos, or game cinematics, offering teams a rapid, integrated pipeline from concept to final video.
