Original: Exploring MiniMax H3: An Omni-Modal Leap in Local Video Generation
Short summary
MiniMax H3 (Hailuo 03) is an open-weights omni-modal video model that generates up to 2K resolution video with native stereo audio in 15-second clips. It unifies text-to-video, image-to-video, reference-based motion transfer, and first-and-last-frame control into a single model runnable locally via ComfyUI, even on modest GPUs like an RTX 3060. The integration of synchronized audio generation eliminates post-processing steps, streamlining creative workflows.
