What the comfyui minimax h3 Setup Delivers for Creators
Inside ComfyUI, the comfyui minimax h3 workflow loads MiniMax's omni-modal model as open weights. Because text, images, video, and audio share one context, dialogue, effects, and music are modeled alongside the visuals in a single pass. Clips can reach roughly 15 seconds at 2K and 24fps, and every parameter stays editable at the node level.
- Built-In Stereo SoundSpeech, effects, and music are rendered in the same pass as the picture, then muxed into one MP4 by the comfyui minimax h3 nodes.
- Local, Open-Weight FreedomHost the comfyui minimax h3 model on your own machine and adjust resolution, length, and diffusion settings freely, with no API caps.
- Mix Text, Image, Video & AudioFeed prompts alongside picture, clip, and audio references so a face, art style, movement, camera path, or voice carries through the comfyui minimax h3 nodes.
Setting Up the comfyui minimax h3 Workflow
Three quick steps take you from a fresh ComfyUI install to open-weight clips with native audio.
Capabilities of the comfyui minimax h3 Setup
From three ready-made ComfyUI templates and open-weight multimodal inference to native stereo sound, reference-guided control, and optional Sage Attention speedups, the comfyui minimax h3 setup covers a full local video pipeline.
Three Ready-Made Templates
Text-to-video, image-to-video, and reference-to-video samples all come bundled in the comfyui minimax h3 template library, one for each generation mode.
One Shared Multimodal Context
Text, stills, footage, and sound are interpreted jointly by the comfyui minimax h3 model, so different reference kinds can be blended in a single run.
Guided by Your References
Pin down a face, an art style, a movement, a camera path, or a voice using up to 9 images, 3 videos, and 3 audio clips through the R2V node.
Crisp On-Screen Text and Logos
Lettering and brand marks come out sharp with the model, and you can describe how each reference relates to the others in plain language.
Faster Runs with Sage Attention
Drop the Patch Sage Attention KJ node into the graph to nearly double throughput while barely touching the quality of your output.
Resolution and Duration Grid
The Resolution Selector derives width and height from aspect ratio and megapixel targets, snapped to a 32-pixel grid, with duration stepping in 17-frame blocks at 24fps.
comfyui minimax h3: Questions Answered
Quick answers on installing, running, and tuning the MiniMax H3 model inside ComfyUI.
What exactly is the comfyui minimax h3 workflow?
It is the native ComfyUI implementation of MiniMax H3, an omni-modal generation model MiniMax published as open weights. In one forward pass it reads text, images, footage, and sound, then writes a video file that already carries stereo audio.
How high can the output resolution go?
Clips from the comfyui minimax h3 workflow can hit 2K at 24fps and run around 15 seconds. The native canvas keeps a 768px short edge, tops out at 768x1344, and snaps dimensions to multiples of 32.
Which generation modes ship with it?
Three samples come bundled: text-to-video, image-to-video with optional first- and last-frame anchoring, and reference-to-video, which pins a character, style, motion, camera path, or voice.
Does the output include audio?
It does. Voice, effects, and music are synthesized as native stereo sound by the comfyui minimax h3 model, written in the same pass as the picture and delivered in one MP4 file.
What do I need to get started?
Bring ComfyUI to 0.30.0 or above, visit Template Library > Video, select a comfyui minimax h3 template, and let the pop-up pull the weights from the Hugging Face Comfy-Org/MiniMax-H3 repository.
Is there a way to make it faster?
Install SageAttention plus the KJNodes extension, then place a Patch Sage Attention KJ node between UNETLoader and BasicGuider in the graph; throughput typically nearly doubles.
