About MiniMax H3 Max

MiniMax H3 Max is an AI video generator that produces 5 to 15 second clips from text prompts, still images, or reference videos. It generates video and audio in a single pass, allowing users to include dialogue, ambience, or other sound direction directly in the prompt. Output resolution is limited to 480P or 768P, with generation times under three seconds for a five-second clip. The tool supports three input modes: Text-to-Video, Image-to-Video, and Reference-to-Video, each following a prompt-and-generate workflow. Users can control output settings such as resolution, duration, and aspect ratio, though 2K output and editing endpoints are not available. The model is hosted only, with no downloadable weights or open-source access. It is designed for short-form content creation, including product videos, social clips, dialogue scenes, stop motion, and stylized animation.
