Meet the comfyui minimax h3 Setup for Local Video Generation
Built on MiniMax's omni-modal model, the comfyui minimax h3 setup loads as open weights directly inside ComfyUI. One shared context reads text, images, video, and audio at the same time, then renders footage whose stereo track — dialogue, effects, and score — is produced in the same forward pass. Clips land at up to 2K and 24fps for roughly 15 seconds, with every node parameter left open for tuning.
- Sound Built Into Every ClipSpeech, effects, and music arrive together with the picture in one MP4, aligned in a single pass through the comfyui minimax h3 graph.
- Runs On Your Own MachineLoad the comfyui minimax h3 model locally and tune resolution, clip length, and every diffusion setting yourself — no API caps in the way.
- Mix Any Reference TypeFeed text, stills, clips, and audio into one run to pin down a character, look, motion, camera angle, or voice through the comfyui minimax h3 nodes.

One Shared Multimodal Context
Text, images, video, and audio are read together by the comfyui minimax h3 model, letting you blend every reference type inside a single run.
References Steer the Output
Pin a character's identity, a look, a motion, a camera move, or a voice from supplied material — as many as 9 images, 3 videos, and 3 audio clips through the comfyui minimax h3 R2V node.
Clean Text and Logo Rendering
On-screen words and brand marks come out sharp with the comfyui minimax h3 model, and plain-language instructions can spell out how references relate.
Faster Renders with Sage Attention
Drop a Patch Sage Attention KJ node into the comfyui minimax h3 graph to roughly double throughput while barely touching output quality.
Resolution and Duration Grid
The comfyui minimax h3 Resolution Selector derives width and height from aspect ratio and megapixels, snapped to the model's 32-multiple grid and 17-frame blocks at 24fps.
Frequently Asked Questions About comfyui minimax h3
Answers to the questions people ask most about running MiniMax H3 locally through ComfyUI.
What exactly does comfyui minimax h3 do?
It is ComfyUI's built-in support for MiniMax H3, an omni-modal generation model that MiniMax released as open weights. From text, images, video, and audio references it renders footage with stereo audio in one forward pass.
How good is the output?
Clips from the comfyui minimax h3 pipeline go up to 2K at 24fps and run about 15 seconds. The native canvas uses a 768px short edge, topping out at 768x1344 pixels and rounded to a multiple of 32.
Which generation modes can I pick from?
The comfyui minimax h3 template library carries three examples: text-to-video (T2V), image-to-video (I2V) with optional first and last frame control, and reference-to-video (R2V) for locking character, style, motion, camera, or voice.
Is audio produced as well?
Yes. The comfyui minimax h3 model renders stereo audio — voice, effects, and music — alongside the visuals in one pass and muxes everything into a single MP4 file.
How do I begin?
Update ComfyUI to 0.30.0 or newer, open Template Library > Video, select a comfyui minimax h3 graph, and accept the pop-up that pulls models from the Hugging Face Comfy-Org/MiniMax-H3 repository.
Any way to make it faster?
Install SageAttention and the KJNodes pack, then insert a Patch Sage Attention KJ node between the UNETLoader and BasicGuider in the comfyui minimax h3 graph to roughly double rendering speed.
