youtube-guitar-tab-parser - CLI tool to convert YouTube guitar lessons to PDF tabs

Show HN: YouTube Guitar Tab Parser

Transform any YouTube guitar lesson video into a clean, printable PDF tablature with this powerful CLI tool. By leveraging Claude vision and advanced frame sampling, it automatically detects the tab region, crops relevant frames, and deduplicates lines based on bar numbers to eliminate redundant cursor movements. The result is a perfectly stitched PDF document ready for practice, complete with the video title as a heading. Requiring only Node.js, yt-dlp, ffmpeg, and an Anthropic API key, this tool streamlines the learning process by turning dynamic video content into static, easy-to-read sheet music instantly.

"Because the bar number is constant while the playback cursor sweeps a line and only changes when the score advances, this collapses all the near-identical cursor frames of a line into a single page."
