README

MiniMax H3 Max generates 5-15 second videos at 480P or 768P from text, first/last frames, or reference images and videos through ReachAPI's asynchronous task API.
  • MiniMax H3 Max supports text-to-video, first-frame image-to-video, first-and-last-frame generation, and multimodal reference workflows.
  • Multimodal reference mode accepts up to 9 reference images and 3 reference videos. Frame inputs and reference media cannot be mixed in one request.
  • Text-only requests require a fixed aspect ratio. Frame modes always use the input image ratio, while reference mode supports an effective fixed ratio or adaptive source ratio.
