Getting Started with comfyui minimax h3
Produce open-weight video with native audio in three simple steps using the comfyui minimax h3 pipeline.
Key Capabilities of the comfyui minimax h3 Pipeline
The comfyui minimax h3 workflow includes three native ComfyUI templates, open-weight multimodal generation, native stereo audio, reference-driven control, and Sage Attention acceleration — a complete on-premise video production stack.
Three Ready-Made Workflow Templates
The comfyui minimax h3 template pack provides text-to-video, image-to-video, and reference-to-video examples, covering every generation mode right out of the box.
Unified Multimodal Understanding
The comfyui minimax h3 model handles text, images, video, and audio in a shared context, letting you combine multiple reference types within a single generation.
Reference-Guided Creation
Preserve a character's identity, a visual style, a motion pattern, a camera move, or a voice from references — up to 9 images, 3 videos, and 3 audio clips through the comfyui minimax h3 R2V node.
Crisp Text & Brand Rendering
Spelled-out text and brand logos render with precision using the comfyui minimax h3 model, while instruction following naturally describes relationships between references.
Sage Attention Boost
Accelerate generation roughly 2x with negligible quality drop by inserting the Patch Sage Attention KJ node into the comfyui minimax h3 workflow.
Resolution & Duration Grid System
The comfyui minimax h3 Resolution Selector calculates width and height from aspect ratio and megapixels, snapped to the model's 32-multiple grid and 17-frame-per-block duration at 24fps.
comfyui minimax h3 — Common Questions
Everything you need to know about running the MiniMax H3 model inside ComfyUI.
What exactly is the comfyui minimax h3 workflow?
It's ComfyUI's native integration of the MiniMax H3 omni-modal model, released as open weights. The pipeline generates video with native stereo audio from text, image, video, and audio references in a single forward pass.
What video quality can I expect?
The comfyui minimax h3 workflow produces up to 2K resolution at 24fps for around 15 seconds. Its native canvas uses a 768px short edge, capped at 768x1344 pixels and rounded to a multiple of 32.
Which generation modes are available?
The comfyui minimax h3 template library includes three workflows: text-to-video (T2V), image-to-video (I2V) with optional first/last-frame control, and reference-to-video (R2V) that locks character, style, motion, camera, or voice.

Yes — the comfyui minimax h3 model creates native stereo audio including voice, sound effects, and music, all modeled together with the video in one pass and synced into a single MP4 file.
How do I start generating?
Update ComfyUI to version 0.30.0 or later, open Template Library > Video, select a comfyui minimax h3 workflow, and follow the pop-up to download models from the Hugging Face Comfy-Org/MiniMax-H3 repository.
Is there a way to speed up rendering?
Yes — install SageAttention and the KJNodes custom nodes, then place a Patch Sage Attention KJ node between the UNETLoader and BasicGuider in the comfyui minimax h3 workflow to roughly double rendering speed.
