ComfyUI-FunPack v5 "Cunning Cranberry"

FunPack v5 is here. It is a browser studio for video inside ComfyUI: a timeline with one clip per scene, a Composer for your prompts, pipeline cards instead of graphs, and modules that learn from your ratings - all on the regular ComfyUI backend.

   

Important

FunPack is a hobby project maintained by a single person. It's crafted for my personal needs mostly, and I can't test every single possible variant of usage to confirm it's bug-free and working as intended. If you had found a bug or you want to request a new feature, feel free to add an entry to Issues - that would be the most appreciated.

What v5 is

A rewrite from scratch, not an update of 4.x. Every feature is a module that announces itself, so nothing can be forgotten in the UI, no wire can be missed, and a module that fails to load is simply left out while the run carries on. Open it at /funpack/ in your browser.

• Timeline studio: one clip per scene, media bin, preview, takes, rating, Export, Render, a project wizard and a guided tour.
• Composer: write the story in one box, with a cut word, templates, $variables and shortcuts.
• Models & Pipeline: the pipeline as cards, not a graph. Pick files, swap or add nodes (any installed custom node), wire outputs to inputs, import a ComfyUI workflow. The server refuses what would not build and says why.
• Modules: switch each feature on or off in Settings. A pipeline runs without an optional node whose module is missing, and tells you so.
• Learning from ratings: rate a clip and the guidance, steering and prompt modules start acting on your taste once they have enough ratings.
• Auto Montage: builds a new cut from your rendered clips; the originals stay untouched.

The full list of features, and what is proven and what is experimental, is in CHANGELOG.md.

Installation

With git, inside your ComfyUI/custom_nodes directory:

git clone https://github.com/digital-garbage/ComfyUI-FunPack

comfy-cli (comfy node install ComfyUI-FunPack) and ComfyUI-Manager install what is published on Comfy Registry. They give you 5.0 only once it is published there: check Settings > About FunPack after installing.

Dependencies

FunPack includes a requirements.txt file for its Python dependencies.

Install them with:

pip install -r requirements.txt

FunPack uses your existing ComfyUI/PyTorch install.

Models

• MiniMax H3: the model v5 is built and tested around.
• Stable Diffusion 1.5: experimental.
• LTX 2.x: UNTESTED. It has never been run on a real LTX model and nobody plans to test it soon. You are free to try it; if you hit problems, please report them in Issues.

Documentation

Start with How to start generating with FunPack. The app also has a guided tour: Help -> Start tour.

Version history is available in CHANGELOG.md.

Classic FunPack (4.x)

FunPack 4 was a different app: Cutting Room, with Easy Gen as its simple mode, and no modules. It is no longer developed, but it is kept for anyone who prefers it: git clone -b v4-classic https://github.com/digital-garbage/ComfyUI-FunPack, or browse the v4-classic branch.

Feedback

If you have suggestions, questions, or ideas for new features, feel free to open an issue or submit a pull request.

Intent

FunPack is provided under GNU General Public License V3, which gives you broad rights to use, modify and distribute the original/modified version of it as long as the original license text is included. FunPack places no limitations on types of content you can generate by using it, meaning both SFW and NSFW content are fine as long as you don't violate your local laws. GPLv3 does not grant you rights for such violations.

However, I do not endorse using FunPack and/or demonstrating it alongside morally and legally questionable/prohibited content, including:

• Non-consensual explicit depiction of a real person;
• Explicit depiction of minors;
• Depiction of violence and gore targeted at a real person.

I do not provide support to users who use FunPack in such cases, and in case I detect it, any support will be immediately ceased.

Thanks for understanding.

Thank you

I express my deepest gratitude to:

• OpenAI and ChatGPT Codex;
• xAI and Grok Build;
• Anthropic and Claude Code;
• Team Cursor and Composer model;
• DeepSeek team and model;
• Google and Gemini;
• Lightricks and LTX-Video model;
• ComfyUI-LTXVideo — LTX model loaders and nodes used by the built-in Cutting Room pipeline;
• ComfyUI-VideoHelperSuite — video combine and helper nodes for montage export;
• ComfyUI-KJNodes — utility nodes used by the built-in pipeline;
• OpenCut — the in-browser non-linear video editor whose UI and interaction patterns inspired the FunPack Movie Editor;
• ComfyUI and its whole community.

Without all of you, this project would've been impossible.

With <3
