ComfyUI-N-Nodes

Introduction to ComfyUI-N-Suite

ComfyUI-N-Suite is an innovative suite of custom nodes designed for ComfyUI, a creative framework that facilitates intuitive user interaction. This suite expands the capabilities of ComfyUI by providing integer, string, and float variable nodes, as well as GPT and video nodes. These tools are specifically crafted to enhance the range of features in ComfyUI, making the user experience more versatile and comprehensive.

Important Considerations

While these nodes have been extensively tested in the default Windows environment offered by ComfyUI and a specific Paperspace environment, compatibility with other environments has not been confirmed. This is an important note for users intending to implement the suite in different settings.

Installation Instructions

1. Begin by cloning the repository into ComfyUI's custom_nodes directory with the command:

   git clone https://github.com/Nuked88/ComfyUI-N-Nodes.git
   

2. Although the need for running dependency batch files for GPU-compatible GPT nodes has been eliminated, if you are utilizing the Moondream model via GPTLoaderSimple, make sure to execute 'install_extra.bat' to download required transformers.

3. After following these steps, ensure to restart ComfyUI to complete the setup.

If you run into compatibility issues with other nodes, you can reverse changes using the 'remove_extra.bat' script. This suite automatically loads all custom scripts and nodes upon startup.

Key Updates

Significant updates have been made to this suite, including a comprehensive rewrite of its nodes to prevent future conflicts with other extensions. Due to these updates, existing workflows using older nodes are incompatible. To address this, a migration tool is available to automatically update workflows.

For removing the suite, delete the ComfyUI-N-Nodes and comfyui-n-nodes folders from the respective directories, and remove n-styles.csv files from the styles directory.

Features

Video Nodes

LoadVideoAdvanced

This node allows for uploading a video file and extracting its frames into ComfyUI.

Inputs include:

• The video file
• Desired frame rate (original, half, or quarter speed)
• Frame resizing options
• Frame extraction limits

Outputs are:

• Extracted frames as PyTorch tensors
• Metadata like frame rate and frame number

SaveVideo

This node saves the extracted frames back into a video file. It offers options for saving the frames individually or as a compressed video.

LoadFramesFromFolder

Load frames from a specified folder, with options to adjust FPS, providing easy access to pre-extracted frames for further processing.

FrameInterpolator

This node enhances video playback by interpolating between frames for smoother motion.

Variable Nodes

These simple nodes overcome limitations in link connections in primitive nodes and provide integer, float, and string variable nodes.

GPTLoaderSimple and GPTSampler

These nodes bring text generative capabilities using GGUF GPT models into ComfyUI. Users can select from supported models like GGUF LLM, Llava, Moondream, and Joytag.

Image Pad For Outpainting Advanced

This node offers powerful outpainting techniques by extending and enhancing images.

Dynamic Prompt

Generates dynamic prompts by combining constants with randomly selected variable tags, creating versatile and customizable input prompts.

CLIP Text Encode Advanced (Experimental)

This experimental node allows encoding positive and negative prompts in one single node, supporting advanced style management.

Troubleshooting

There has been a conflict between the SaveVideo node and AnimateDiff, resolved in an updated version available on GitHub.
