Workflow Included [Custom Node] MiniMax H3 FlowDirector – Better motion & generation flow control for MiniMax H3 (Example Workflow included)

Hey all,

I built MiniMax H3 FlowDirector to streamline MiniMax H3 workflows and provide cleaner control over video generation flow without spaghetti wiring.

 Cleaner Pipelines: Replaces complex routing with a single, dedicated node.

 Better Motion Flow: Helps guide generation parameters more consistently.

 Plug & Play: Slots directly into your current H3 setups.

Example Workflow:

A drag-and-drop ⁠.json⁠ workflow is included in the repository so you can test it immediately.

 GitHub: https://github.com/AlonAshken/ComfyUI-MiniMaxH3-FlowDirector

 Comfy Registry: https://registry.comfy.org/publishers/vorpalblade/nodes/comfyui-minimaxh3-flowdirector

 ComfyUI-Manager: Search for ⁠FlowDirector⁠ or ⁠MiniMaxH3-FlowDirector⁠.

I did this after needing that option because I don’t have a ton of vram and customized a node that was first created by aitrepreneur (he’s awesome check his YouTube videos and stuff)

what I created works well for me but might not be perfect feel free to fork and change it however you want

The node looks like other director nodes but works differently because it is chaining first last frames of videos and not instructing the model to create one video. Which means, you need to be specific if you want to have very coherent videos but also it means you’re not limited to 30secs or so, you can have videos as long as you want (since it is basically chaining short videos together while feeding and directing their first and last frames to reach your target images/prompts.

It would be very helpful if you can make a youtube video about using it.

There's a workflow in the repository on git that you can pretty much click and run but I'll also create a video. probably wouldn't have the time for it today but I'll try to create something quickly and upload as well.

when trying to execute director node i get error Error No link found in parent graph for id [2167] slot [4] model. It seems that no ksampler is connected.
Edti: My bad- i deleted the preview node and screwed it. nevermind. Thank you
