# H3 Editor

> A timeline video editor for MiniMax H3 that runs inside ComfyUI. Write shots, render them on your own GPU, and cut picture and sound together. Everything the editor does is an HTTP call, and an agent skill teaches the whole workflow. It needs no other custom node pack.

H3 Editor is a ComfyUI custom node pack under the GNU GPL v3.0. To install it, run `git clone https://github.com/igorls/comfyui-h3-editor` in ComfyUI's `custom_nodes` folder, then `pip install -r comfyui-h3-editor/requirements.txt`, and restart ComfyUI. It needs a recent ComfyUI with its built-in MiniMax H3 support and about 54 GB of model files, which the pack does not download. The editor opens from ComfyUI's sidebar, at `/h3take/editor` on the ComfyUI server (by default `http://127.0.0.1:8188`). Renders run on that ComfyUI's GPU. So far it has been tested on one 96 GB GPU.
