Getting Started with the comfyui minimax h3 Node in ComfyUI
Produce open-weight footage with synchronized audio in three straightforward steps using the comfyui minimax h3 node.
Feature Set of the comfyui minimax h3 Integration
From three built-in ComfyUI templates to open-weight multimodal generation, reference-driven control, and Sage Attention acceleration, the comfyui minimax h3 integration gives you a complete local production suite.
Three Built-In Template Types
The node comes with ready-made T2V, I2V, and R2V setups, each demonstrating a distinct generation mode.
Unified Multimodal Understanding
Because the model processes text, imagery, motion, and sound as one context, you can merge every reference type in a single run.
Reference-Based Creation
For the R2V template, attach up to 9 images, 3 videos, and 3 audio files to keep a character, look, movement, camera path, or voice consistent.
Precise Text and Brand Display
The comfyui minimax h3 model renders written words and logos clearly, and it follows natural-language instructions that define relationships between references.
Sage Attention Acceleration
Insert the Patch Sage Attention KJ node into the comfyui minimax h3 graph to nearly double your generation speed while keeping quality intact.
Resolution and Duration Presets
The resolution picker calculates dimensions from ratio and megapixels, snapping to the model's 32-pixel grid and 17-frame blocks at 24fps.
