YouTube Video Highlights Extractor

Key Features and Highlights

This workflow accepts a YouTube video ID and calls a third-party API to retrieve the video's "most replayed" data. It automatically filters out highlight segments with high intensity (intensity > 0.6) and removes temporally close duplicate moments. The final output is a structured, human-readable list of highlights, each accompanied by a direct YouTube timestamp link for quick navigation to key moments within the video.

Core Problem Addressed

Manually finding highlights in long videos is time-consuming and labor-intensive.
