Show HN: YouTube Guitar Tab Parser
TL;DR
A command-line interface (CLI) tool has been developed to convert YouTube guitar lesson videos into PDF guitar tabs. It utilizes Claude vision to identify and extract the tab region from video frames, creating a clean, organized PDF.
✦ Why It Matters
Guitarists can immediately use this tool to convert any YouTube guitar lesson into a PDF tab for easier practice.
Key Takeaways
- Install the tool using npm and set up your API key.
- Run the CLI with a YouTube video URL to generate a PDF.
- Customize screenshot intervals and resolution if needed.
- Use the output PDF for easy reference while playing guitar.
How It Works
The tool downloads the YouTube video and samples frames at specified intervals. It employs the Claude vision model to detect the tab region by analyzing a grid drawn on the frames.
The tool then crops the frames to focus on the tab, removes duplicates based on bar numbers, and compiles the unique lines into a PDF document using pdf-lib.
