What the comfyui minimax h3 Node Pack Brings to ComfyUI
Packed as open weights inside ComfyUI, the comfyui minimax h3 pipeline reads text, stills, footage, and audio within one shared context. Voice, effects, and music are modeled alongside the picture in a single forward pass, so the finished MP4 arrives with stereo sound already in sync — up to 2K at 24fps for roughly 15 seconds, with every node parameter open to tweaking.
- Stereo Audio, Built InSpeech, effects, and music are produced together with the picture and delivered in one MP4, already in sync straight out of the comfyui minimax h3 pipeline.
- Open Weights, Full ControlBecause the comfyui minimax h3 checkpoints run on your own machine, you decide resolution, length, and every diffusion parameter yourself — no API ceilings.
- Mix Text, Image, Video & AudioFeed several reference types into a single run and hold a face, look, movement, camera angle, or voice steady through the comfyui minimax h3 nodes.
Set Up comfyui minimax h3 in Three Steps
Go from a fresh ComfyUI install to open-weight video with native audio in three quick steps using the comfyui minimax h3 templates.
Key Features of the comfyui minimax h3 Node Pack
From three ready-made ComfyUI templates to open-weight multimodal reasoning, synchronized stereo sound, reference-locked control, and optional Sage Attention acceleration, the comfyui minimax h3 node pack covers a full local video pipeline.
Three Ready-Made Templates
Text-to-video, image-to-video, and reference-to-video examples ship in the comfyui minimax h3 template library, one for each generation mode, with no wiring required.
One Shared Omni-Modal Context
Text, pictures, footage, and sound are understood together in a single context by the comfyui minimax h3 model, so every reference type can inform one output.
Lock Identity, Style & Motion
Pin a character's face, a visual style, a movement, a camera path, or a voice from your references — the comfyui minimax h3 R2V node accepts up to 9 images, 3 videos, and 3 audio clips.
Clean Text and Logo Rendering
Lettering and brand marks come out legible with the comfyui minimax h3 model, and natural-language instructions let you describe how references relate.
Sage Attention Acceleration
Add the Patch Sage Attention KJ node to your comfyui minimax h3 graph and generation runs roughly twice as fast with almost no quality drop.
Resolution and Duration Grid
The comfyui minimax h3 Resolution Selector derives width and height from your ratio and megapixel target, snapped to the model's 32-multiple grid and 17-frame blocks at 24fps.
comfyui minimax h3: Frequently Asked Questions
Answers to the questions creators ask most about running the MiniMax H3 model inside ComfyUI.
What exactly is the comfyui minimax h3 workflow?
It is ComfyUI's built-in support for MiniMax H3, an omni-modal generation model MiniMax released as open weights. One forward pass turns text, images, video, and audio references into video that already carries stereo sound.
What resolution and frame rate can I get?
Renders reach up to 2K at 24fps for around 15 seconds. The native canvas targets a 768px short edge, tops out at 768x1344 pixels, and rounds dimensions to a multiple of 32.
Which generation modes ship with it?
Three examples come in the comfyui minimax h3 template library: text-to-video (T2V), image-to-video (I2V) with optional first- and last-frame control, and reference-to-video (R2V) that locks character, style, motion, camera, or voice.
Does it produce sound as well?
It does. Voice, effects, and music are generated as native stereo audio by the comfyui minimax h3 model in the same pass as the picture, then delivered in one synchronized MP4.
What do I need to get started?
Update ComfyUI to 0.30.0 or later, go to Template Library > Video, pick a comfyui minimax h3 example, and follow the pop-up to download the models from the Hugging Face Comfy-Org/MiniMax-H3 repository.
Is there a way to render faster?
Yes — install SageAttention along with the KJNodes custom nodes, then insert a Patch Sage Attention KJ node between the UNETLoader and BasicGuider in the comfyui minimax h3 graph to roughly double throughput.
Put the comfyui minimax h3 Workflow to Work
Run MiniMax H3 on your own hardware inside ComfyUI — open weights, synchronized stereo audio, and full parameter control, with text-to-video, image-to-video, and reference-to-video templates ready to launch.
