Follow these three steps to produce open-weight videos with built-in sound using the comfyui minimax h3 workflow.
Core Features of the comfyui minimax h3 Workflow
The comfyui minimax h3 workflow ships with three ready-made ComfyUI templates, open-weight multimodal generation, built-in stereo audio, reference-driven control, and optional Sage Attention acceleration — a complete local video toolkit.
Three Built-In Templates
The comfyui minimax h3 library includes text-to-video, image-to-video, and reference-to-video templates, each covering one generation mode out of the box.
All-in-One Multimodal Context
The comfyui minimax h3 model reads text, photos, footage, and sound in one shared context, allowing you to blend several reference types in a single generation.
Reference-Driven Production
Lock identity, style, motion, camera, or voice with references — up to 9 images, 3 videos, and 3 audio clips routed through the comfyui minimax h3 R2V node.
Accurate Text and Brand Rendering
The comfyui minimax h3 model renders spelled-out copy and brand assets cleanly, and follows natural-language instructions about how references relate.
Sage Attention Boost
Put a Patch Sage Attention KJ node into the comfyui minimax h3 workflow and you can roughly double generation speed with only a slight quality trade-off.
Resolution and Duration Grid
The comfyui minimax h3 Resolution Selector calculates width and height from aspect ratio and megapixels, matching the 32-multiple grid and a 17-frame block at 24fps.
