MiniMaxH3.app

MiniMaxH3.app is an AI video generator that produces native 1440p/2K video with stereo audio. You can start from a text prompt, upload a first and last frame to control motion, or use multiple reference images, videos, and audio clips — up to 12 assets total — to guide the output. Every generation includes synced stereo sound, including dialogue, sound effects, and ambience, so you don't need to add audio separately.

The tool supports several workflows: Text-to-Video, First/Last Frame, and Omni Reference. The Omni Reference mode allows you to upload images, videos, and audio and refer to them in your prompt. You can also perform instruction-based editing, like swapping a subject's wardrobe or replacing a green-screen background, by providing reference assets. The output resolution is native, not upscaled, and you can choose from six aspect ratios and durations up to 15 seconds. The interface is straightforward: write a prompt, upload assets, pick settings, and generate. New accounts receive 100 free credits, enough for about one 5-second 2K video.

Video creators, marketers, and filmmakers can use MiniMaxH3.app to quickly produce product commercials, short drama clips, or character-content for games without needing video production experience. The editing features also make it useful for post-production tasks like subject replacement or background swaps. It is a practical tool for anyone who needs short, high-quality video content fast.
