Clips stretch to roughly 15 seconds at 2K/24fps, with every node parameter left in your hands.

comfyui minimax h3: Questions Answered
Quick answers on running MiniMax H3 locally inside ComfyUI, from first install to output specs.
What exactly is the comfyui minimax h3 workflow?
It's ComfyUI's built-in support for MiniMax H3, an omni-modal model MiniMax published as open weights. Prompts, pictures, clips and audio go in together, and one pass returns video paired with its own stereo soundtrack.
How good is the output quality?
Renders reach roughly 15 seconds at up to 2K and 24fps. The native canvas keeps a 768px short edge, tops out at 768x1344 pixels, and snaps dimensions to multiples of 32.
Which generation modes ship with it?
Three examples come bundled: text-to-video, image-to-video with optional first and last frame control, and reference-to-video, which holds a character, style, motion, camera angle or voice in place.
Will it produce audio on its own?
Yes. Voice, sound effects and music are all synthesized by the model and delivered in the same MP4 as the picture, so nothing needs syncing afterwards.
How do I get it running?
Install ComfyUI 0.30.0 or newer, browse Template Library > Video, load one of the comfyui minimax h3 graphs, and accept the pop-up that fetches weights from the Hugging Face Comfy-Org/MiniMax-H3 repository.
Is there a way to render faster?
Add the KJNodes pack and SageAttention, then insert a Patch Sage Attention KJ node between the UNETLoader and BasicGuider in the comfyui minimax h3 graph — rendering time roughly halves.
