What Makes the comfyui minimax h3 Pipeline Stand Out
Built on MiniMax's omni-modal engine and shipped as open weights, the comfyui minimax h3 pipeline lives inside ComfyUI. It reads text, stills, video, and audio in one shared context, so voice, effects, and music are modeled alongside the picture in a single forward pass. Expect up to 2K at 24fps for roughly 15 seconds, with every parameter exposed at node level.
- Stereo Sound Baked InSpeech, effects, and music are synthesized together with the footage and muxed into one MP4, staying in sync through a single pass of the comfyui minimax h3 workflow.
- Runs Fully on Your MachineLoad the comfyui minimax h3 model locally and tune resolution, clip length, and each diffusion setting yourself — no API caps and no per-render fees.
- Mix Any Reference TypeFeed text, stills, video, and audio into one run to pin down a character, art style, motion path, camera move, or voice with the comfyui minimax h3 nodes.
Running the comfyui minimax h3 Workflow in Three Moves
Three short steps take you from a fresh install to open-weight video with built-in audio using the comfyui minimax h3 workflow.
Capabilities Inside the comfyui minimax h3 Workflow
Three ready-made ComfyUI templates, open-weight multimodal generation, stereo audio, reference-driven control, and optional Sage Attention acceleration — the comfyui minimax h3 workflow is a full local video studio.
Three Ready-Made Templates
The comfyui minimax h3 template library includes text-to-video, image-to-video, and reference-to-video examples, each one covering a single generation mode straight away.
One Shared Multimodal Context
Text, images, video, and audio are all interpreted together by the comfyui minimax h3 model, letting you blend every reference type inside a single generation.
Lock Down Characters and Style
Pin a character's identity, an art style, a motion, a camera move, or a voice from your source material — up to 9 images, 3 videos, and 3 audio clips through the comfyui minimax h3 R2V node.
Clean Text and Logo Rendering
Spelled-out words and brand marks come out sharp with the comfyui minimax h3 model, and natural-language instructions can describe how references relate to each other.
Optional Sage Attention Boost
Drop a Patch Sage Attention KJ node into the comfyui minimax h3 workflow to roughly double throughput while barely touching output quality.
Smart Resolution and Duration Grid
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-per-block timing at 24fps.
comfyui minimax h3: Frequently Asked Questions
Answers to the questions people ask most 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, MiniMax's omni-modal generation model released with open weights. The workflow turns text, images, video, and audio references into video with native stereo audio in one forward pass.
How good is the output quality?
The comfyui minimax h3 workflow can output up to 2K at 24fps for around 15 seconds. Its native canvas uses a 768px short edge, tops out at 768x1344 pixels, and rounds dimensions to a multiple of 32.
Which generation modes come bundled?
Three examples ship in the comfyui minimax h3 template library: text-to-video (T2V), image-to-video (I2V) with optional first/last-frame control, and reference-to-video (R2V) for locking character, style, motion, camera, or voice.
Does the workflow produce audio too?
It does — the comfyui minimax h3 model renders native stereo audio, covering voice, sound effects, and music, modeled alongside the picture in one pass and synced inside a single MP4 file.
What is the quickest way to get started?
Update ComfyUI to 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 generation?
Yes — install SageAttention plus 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 generation speed.
Build Your Next Clip with the comfyui minimax h3 Workflow
Run MiniMax H3 on your own hardware inside ComfyUI — open weights, stereo audio, and every parameter in your hands, with text-to-video, image-to-video, and reference-to-video workflows ready from the start.
