MiniMax H3 Omni-Modal Video Model with Open Weights Now Supported in ComfyUI
Key points
- MiniMax H3 is an open-weights omni-modal video model.
- It supports text, image, video, and audio inputs for video generation.
- Outputs include native stereo audio and up to 2K resolution for 15-second clips.
- ComfyUI offers immediate integration and local execution on a 3060 GPU.
MiniMax H3 Release and ComfyUI Integration
MiniMax has launched its H3 video model with open weights, marking its third generation of video models. This release includes immediate support within ComfyUI, allowing users to access its capabilities from day one.
The H3 model is designed for local execution, with optimizations enabling it to run on GPUs such as the NVIDIA RTX 3060.
Omni-Modal Capabilities
H3 functions as an omni-modal video model, accepting various inputs including text, images, video, and audio. It generates video content with integrated stereo sound, producing clips up to 15 seconds long and at resolutions up to 2K.
This model combines multiple tasks into one, understanding multimodal contexts to resolve inputs against a prompt that defines their relationships.
Key Features
The model supports text-to-video, image-to-video, and reference-to-video generation, allowing users to bring images to life or transfer motion from a reference video. It also features first-and-last-frame control, enabling users to define the start and end frames of a generated clip.
A notable feature is its native stereo audio generation, which is produced simultaneously with the video rather than being added as a post-processing step.
Editing and Motion Transfer
H3 facilitates motion transfer, where a reference video can dictate movement, camera angles, or performance, while the subject and style are sourced independently. This capability, combined with in-place editing, supports iterative adjustments to video shots.
