Straightforward answers about setting up and running the comfyui minimax h3 workflow in ComfyUI.
What does the comfyui minimax h3 workflow do?
It's ComfyUI's official template for MiniMax H3, an open-weight omni-modal model from MiniMax. The comfyui minimax h3 workflow accepts text, pictures, clips, and sound as input, then outputs video with built-in stereo audio in one pass.

With the comfyui minimax h3 workflow, you can render up to 2K at 24fps for roughly 15 seconds. The native canvas starts with a 768px short edge, caps at 768x1344, and snaps to multiples of 32.
What input modes come with the template?
The comfyui minimax h3 library provides three built-in workflows: T2V, I2V (with first/last-frame options), and R2V—which can lock a character, aesthetic, motion, camera, or voice from reference inputs.
Is audio included in the output?
Absolutely—the comfyui minimax h3 workflow creates stereo sound, covering speech, SFX, and music, and bakes it into the same MP4 as the visuals, perfectly synced.
What do I need to begin?
Start by updating ComfyUI to 0.30.0+, then open Template Library > Video and select a comfyui minimax h3 template. When prompted, download the open-weight models from the Comfy-Org/MiniMax-H3 repo on Hugging Face.
Is there a way to render faster?
Sure—install SageAttention and the KJNodes pack, then place a Patch Sage Attention KJ node between UNETLoader and BasicGuider in your comfyui minimax h3 graph. That typically cuts render time by half.
