A set of ComfyUI nodes for experimenting with video generation workflows based on WAN, HunyuanVideo, LTX, and similar models.

The dev branch is intended for testing unfinished changes, implementing new logic and basically, flipping everything just because I can. It can be broken, renamed, or changed without warning.

Use only main if you want the most stable version of this node pack. Bug reports based on dev version will be ignored.

FunPack 3.0 introduces the Cutting Room — a dedicated montage editor at /funpack/movie inside ComfyUI. It is the primary surface for building multi-scene projects, previewing on a real timeline, and driving FunPack Studio + the LTXAV Scene Chain Sampler without wiring a graph by hand.

Going forward, new features and UX work target the Cutting Room frontend. The classic ComfyUI node popups (Studio, Refiner V2, Scene Chain Sampler, and other pre-3.0 nodes) remain fully usable but will receive bugfixes only — no significant UI reworks unless a fix requires it. If you live in ComfyUI graphs, nothing breaks; if you want the full montage workflow, use the Cutting Room.

See docs/MovieEditor.md for complete Cutting Room documentation.

FunPack is available on Comfy Registry and can be installed in any of these ways:

1. With comfy-cli: comfy node install ComfyUI-FunPack
2. With git, inside your ComfyUI/custom_nodes directory: git clone https://github.com/digital-garbage/ComfyUI-FunPack
3. With ComfyUI-Manager: Open Custom Nodes Manager, search for ComfyUI-FunPack, and click Install.

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. The expected baseline is transformers >= 5.0.0

hpsv3 is optional and only used by the FunPack StoryMem Keyframe Extractor quality filter, so it is not installed by default.

Install it manually only if you need that feature:

pip3 install hpsv3 --no-build-isolation

Installing hpsv3 can break Prompt Enhancer and Story Writer, because hpsv3 depends on a transformers version that conflicts with the version those LLM-based nodes require.

FunPack's LLM nodes require transformers >= 5.0. The version required for hpsv3 is strictly transformers==4.45.2. Installing any version different from it will result in broken quality detector.

If you install hpsv3, use --no-build-isolation. Optionally, specify the exact version - pip install transformers==4.45.2 --no-build-isolation.

Per-node documentation is available in the docs folder.

Start with:

• docs/MovieEditor.md for the FunPack Cutting Room (Movie Editor)
• docs/FunPackVideoRefinerV2.md for FunPack Video Refiner V2
• docs/FunPackVideoRefinerV2QuickGuide.md for a short Discord-friendly Refiner V2 guide
• docs/FunPackLTXAVSceneChainSampler.md for split-scene LTXV/LTXAV continuation
• docs/FunPackLoraWorkflow.md for the LoRA/refiner helper workflow
• docs/FunPackSceneBuilder.md for scene preset workflows

Version history is available in CHANGELOG.md.

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

FunPack is a hobby project, provided to you by a fellow AI enthusiast who "lives in the trenches" and knows exactly what people seek in video/audio generation workflows.

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.

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;
• ComfyUI and its whole community.

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