The Complete Guide to the comfyui minimax h3 Workflow in ComfyUI
Inside ComfyUI, MiniMax H3 runs as open-weight checkpoints that let you feed text, pictures, footage, and sound into one context window. The comfyui minimax h3 workflow then renders a single MP4 where dialogue, effects, and music are baked into the timeline, at resolutions up to 2K and 24 frames per second. Every node remains editable, giving you granular control.
- Audio and Video in Perfect SyncSpeech, ambient effects, and musical score are produced alongside the footage and merged into a single MP4—no post-sync needed when you use the comfyui minimax h3 integration.
- Local, Limitless TuningHost everything on your own machine and tweak resolution, length, and sampling settings freely with the comfyui minimax h3 node graph, unrestricted by external API quotas.
- Reference Anything, Mix ModalitiesMerge prompts, pictures, existing footage, and audio cues in a single pass, and use the comfyui minimax h3 nodes to pin down a character's identity, visual style, movement, camera behavior, or vocal tone.
Running the comfyui minimax h3 Workflow: A Simple 3-Step Guide
Follow this quick walkthrough to activate the comfyui minimax h3 node set and produce video with built-in audio in ComfyUI.
Key Features of the comfyui minimax h3 Workflow
From three ready-made ComfyUI templates to open-weight multimodal generation, built-in audio, reference control, and optional Sage Attention acceleration—the comfyui minimax h3 pipeline forms a full local video studio.
Three Built-In Template Presets
The comfyui minimax h3 template collection includes ready-made flows for text-to-video, image-to-video, and reference-to-video, with each mode working immediately after loading.
One Model, Every Modality
Thanks to the comfyui minimax h3 architecture, text, pictures, video, and sound share the same context window, enabling multimodal references in a single generation step.
Lock Down Details from References
You can anchor a character's look, art direction, motion, camera path, or voice using up to 9 images, 3 clips, and 3 audio samples through the comfyui minimax h3 reference node.
Clean Text and Brand Accuracy
The comfyui minimax h3 model keeps spelled-out words and brand marks crisp, and it follows natural-language instructions to describe how references relate to each other.
Faster Rendering with Sage Attention
Add the Patch Sage Attention KJ node to the comfyui minimax h3 workflow to roughly double inference speed while keeping visual quality almost intact.
Precise Resolution and Length Grid
The comfyui minimax h3 resolution selector maps aspect ratio and megapixels to width/height, snaps to the model's 32-step grid, and follows the 17-frame block at 24fps.
FAQ: comfyui minimax h3 in ComfyUI
Straightforward answers about deploying the comfyui minimax h3 pipeline in ComfyUI.
What exactly does the comfyui minimax h3 workflow do?
This is the official ComfyUI implementation of MiniMax H3, an open-weight, omnimodal model from MiniMax. It lets you combine text, images, footage, and sound sources in one forward pass to create video with synchronized stereo audio.
What resolution and frame rate can I expect?
With the comfyui minimax h3 workflow, output reaches 2K at 24fps for roughly 15 seconds. Its canvas uses a 768px short edge, caps at 768×1344 pixels, and rounds dimensions to multiples of 32.
What generation modes come with the comfyui minimax h3 setup?
The comfyui minimax h3 template pack offers three ready-to-run flows: T2V (text to video), I2V (image to video, with optional first/last frame constraints), and R2V (reference to video) for retaining the subject, look, movement, camera, or voice.
Is audio truly generated alongside the video?
Yes. The comfyui minimax h3 model synthesizes voice, sound effects, and music as part of the same pass, delivering a single MP4 where audio and visuals are automatically aligned.
What do I need to do to begin?
First upgrade ComfyUI to v0.30.0+, then open Template Library > Video and select a comfyui minimax h3 preset. Follow the dialog to fetch the open-weight model files from the Comfy-Org/MiniMax-H3 Hugging Face repo.
Is there a way to make generation faster?
Yes. Install SageAttention and the KJNodes custom nodes, then insert a Patch Sage Attention KJ node between UNETLoader and BasicGuider in your comfyui minimax h3 graph. That can roughly halve render time.
