seriesmith runs inside the ComfyUI you already have. It uses the models you already have in it. You don’t install anything into ComfyUI’s Python, you don’t need other node packs, and you don’t need ffmpeg. You need:
  • a ComfyUI that runs (developed against 0.38 and later);
  • git.
Windows, in an ordinary Command Prompt (mklink /J needs no administrator rights):
Linux/macOS:
The paths are only examples. Link the folder rather than copying it: seriesmith finds the rest of itself through the link, and a git pull updates what ComfyUI loads.

​
2. Start ComfyUI

seriesmith shows up in ComfyUI:
  • seriesmith Shots and seriesmith Refs in the sidebar;
  • seriesmith Timeline in the bottom panel.
It renders on that ComfyUI. To start, open seriesmith Shots and choose Simple at the top of the sidebar, then A clip. Under What happens?, describe the shot, pick who’s in it and where, and press Generate.

​
Or: the editor on a page of its own

With ComfyUI running, double-click run_seriesmith.bat in the repo (Linux/macOS: ./run_seriesmith.sh).
  • The first time, it sets itself up in the repo’s .venv. That takes a minute or two and needs Python 3.10 or later.
  • Then it opens http://127.0.0.1:8190 in your browser.
It’s the same app as the one inside ComfyUI, with the same projects and settings.

​
Which models it uses

When seriesmith starts and sees ComfyUI, it checks which models have all their files installed. A series that doesn’t name a model renders on the first one it finds:
  • New projects: new series and Simple-mode projects write the choice into their series config, so they keep rendering on it.
  • Your own pick: choose another in Settings (Video model, Picture model).
  • Paid models: hosted Comfy Router models (Seedance, Kling, Veo, …) are never picked by themselves. Add a Comfy API key in Settings to use them (and Comfy Cloud). Saving the key also installs what those need (Comfy’s SDK) in the background, in a few seconds.
No models yet? Every model picker has a What’s missing button. It lists each file the model needs, the ComfyUI folder it goes in, and the download link. With ComfyUI running, seriesmith targets prints the same list from the command line. The smallest complete set is the default pair: MiniMax H3 Ref2VA for video and Krea 2 for pictures (INSTALL.md, The minimum set).

​
What works now, and what’s extra

With just this, you can do all of the following on the models you have:
  • write and build episodes;
  • render shots;
  • make reference pictures;
  • cut the episode;
  • export it.
Some things need extra node packs, model files or software:
  • MiniMax H3 at full quality (its sparse-attention node);
  • generated voice samples;
  • upscaling;
  • post-processing (enhancement, motion blur);
  • matching recorded dialogue;
  • 360s of a place, and turning a character.
Settings → Features… installs any of them for you: tick what you want and press Install. Full setup lists each one with what it needs.
