ComfyUI Extension: ComfyUI Video Segmentation Node

ComfyUI-Video-Segmentation Introduction

ComfyUI-Video-Segmentation is an extension designed to enhance your video editing workflow by automatically segmenting videos into individual scenes. This is achieved using the TransNetV2 deep learning model, which is renowned for its accuracy in detecting shot boundaries in videos. For AI artists, this tool can significantly streamline the process of video editing by automating the tedious task of scene detection, allowing you to focus more on the creative aspects of your projects.

How ComfyUI-Video-Segmentation Works

At its core, ComfyUI-Video-Segmentation leverages the power of TransNetV2, a state-of-the-art neural network specifically designed for shot boundary detection. Imagine watching a movie and being able to pinpoint the exact moment one scene transitions to another—this is what TransNetV2 does, but with the precision and speed of a machine. When you input a video, the extension analyzes it frame by frame, identifying changes in visual content that signify a new scene. If TransNetV2 is unavailable, the extension can fall back on OpenCV, a robust computer vision library, to perform similar scene detection tasks.

ComfyUI-Video-Segmentation Features

• Automatic Scene Detection and Segmentation: The extension automatically detects and segments scenes, saving you time and effort.
• TransNetV2 Integration: Utilizes the TransNetV2 model for high-accuracy shot boundary detection.
• OpenCV Fallback: If TransNetV2 is not available, the extension uses OpenCV for scene detection.
• Configurable Parameters: You can adjust parameters such as minimum scene length and detection threshold to suit your specific needs.
• Output Options: The extension outputs individual video segments, which can be easily managed and edited.

ComfyUI-Video-Segmentation Models

The primary model used in this extension is TransNetV2. This model is specifically designed for detecting shot boundaries in videos, making it highly effective for scene segmentation tasks. TransNetV2 is preferred for its superior accuracy and performance, as demonstrated in various benchmarks. If you are unable to use TransNetV2, the extension can switch to using OpenCV, which provides a reliable alternative for scene detection.

Troubleshooting ComfyUI-Video-Segmentation

Here are some common issues you might encounter while using the extension, along with solutions:

• TransNetV2 Not Found: If you encounter errors related to TransNetV2, ensure that the model is installed correctly. You can install it using the command pip install transnetv2 or ensure the model weights are placed in the correct directory.
• FFmpeg Not Found: FFmpeg is essential for video processing. Make sure it is installed and accessible in your system's PATH. You can download it from FFmpeg's official site (https://ffmpeg.org/download.html).
• Permission Errors: Ensure that the output directory is writable and that you have enough disk space for the segmented videos.
