MiniMax H3 ComfyUI Workflow JSON Library

MiniMax H3 supports several local workflow paths depending on the input and control you need. This library records ready-to-import ComfyUI JSON workflows for text-to-video, image-to-video and multimodal references, while clearly marking assets that are not currently verified in this repository.

Choose the workflow based on the material you already have rather than downloading every graph. For full installation, model placement, VRAM requirements and troubleshooting, use the MiniMax H3 ComfyUI installation guide.

Where Can I Download MiniMax H3 ComfyUI Workflows?

You can download ready-to-import MiniMax H3 ComfyUI JSON workflows from this library for T2V, I2V and reference-to-video. FL2VA and Turbo records remain visible but are not presented as downloads until a distinct, verified JSON asset is registered.

Which MiniMax H3 Workflow Should You Download?

Starting materialRecommended workflowBest for
Text prompt onlyT2VGenerating a scene from text
One starting imageI2VAnimating a still image
First + last frameFL2VAControlling start and end states
Multiple referencesR2V / Ref2VAMultimodal reference control
Existing optimized setupTurboExperimental community inference

If you only have a text prompt, start with T2V. If you already have an image, use I2V. Use FL2VA when both the opening and ending state matter, and use Ref2VA/R2V when multiple image, video or audio references need to guide the result.
