A Closer Look at the comfyui minimax h3 Workflow
The comfyui minimax h3 workflow brings MiniMax's omni-modal generation model into ComfyUI as open weights. Text, images, video, and audio are read together in one shared context, so finished clips carry stereo voice, effects, and music mixed in a single forward pass. Expect up to 2K at 24fps for roughly 15 seconds, with every node parameter open to adjustment.
- Stereo Audio, Generated In-PassVoice, effects, and music are modeled alongside the picture and delivered in one MP4 — no separate audio step anywhere in the comfyui minimax h3 workflow.
- Open Weights, Local ControlBecause the comfyui minimax h3 model runs on your own hardware, resolution, clip length, and diffusion settings stay in your hands, free of API caps.
- Mix Any Reference TypeFeed text, images, video, and audio into a single run to pin down a face, a look, a movement, a camera path, or a voice with the comfyui minimax h3 nodes.
Running the comfyui minimax h3 Workflow, Step by Step
Three quick steps take you from a fresh ComfyUI install to open-weight video with built-in audio using the comfyui minimax h3 workflow.
What the comfyui minimax h3 Workflow Delivers
Three ready-made ComfyUI templates, omni-modal open weights, built-in stereo audio, reference-driven control, and optional Sage Attention acceleration — the comfyui minimax h3 workflow covers a full local production pipeline.
Three Ready-Made Templates
Text-to-video, image-to-video, and reference-to-video examples ship inside the comfyui minimax h3 template library, each covering a different generation mode out of the box.
One Context for Every Modality
Text, images, video, and audio are understood together by the comfyui minimax h3 model, so every reference type can feed a single generation.
References That Lock the Look
Pin a face, a style, a movement, a camera path, or a voice from your source material — the comfyui minimax h3 R2V node accepts up to 9 images, 3 videos, and 3 audio clips.
Clean Text & Brand Elements
Lettering and logos come out crisp with the comfyui minimax h3 model, and natural-language instructions let you describe how references relate to one another.
Sage Attention Acceleration
Add the Patch Sage Attention KJ node to the comfyui minimax h3 workflow to roughly double throughput with only a small quality trade-off.
Precise Resolution & Duration Controls
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.
comfyui minimax h3 — Common Questions
Straight answers about running the MiniMax H3 model inside ComfyUI.
What exactly is the comfyui minimax h3 workflow?
It is ComfyUI's built-in integration of MiniMax H3, an omni-modal generation model MiniMax released with open weights. A single forward pass turns text, images, video, and audio references into video that already carries stereo audio.
How high does the output resolution go?
Clips render at up to 2K and 24fps, running roughly 15 seconds. The native canvas works from 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) for locking a character, style, motion, camera move, or voice.
Is audio included in the output?
Yes. The comfyui minimax h3 model generates stereo audio natively — dialogue, effects, and music are modeled in the same pass as the picture and arrive synced inside a single MP4.
What are the first steps?
Update ComfyUI to 0.30.0 or later, open Template Library > Video, pick a comfyui minimax h3 workflow, and let the pop-up guide you through downloading models from the Hugging Face Comfy-Org/MiniMax-H3 repository.
Is there a way to make generation faster?
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 workflow — generation speed roughly doubles.
Put the comfyui minimax h3 Workflow to Work
Run MiniMax H3 on your own machine in ComfyUI — open weights, stereo audio, and full parameter control, with text-to-video, image-to-video, and reference-to-video templates ready to load.
