ytvideo2pdf 0.1.0

Convert YouTube educational video to crisp PDF notes

Glimpsify (ytvideo2pdf)

Glimpsify extracts slide-like frames from educational videos and builds a PDF of the key visuals (diagrams, formulas, charts). It is optimized for lecture-style videos where text appears on screen over time.

Quick start

1. Install OCR engine (required for text detection)

   • Windows: install Tesseract OCR and make sure tesseract is on PATH.
   • macOS: brew install tesseract
   • Debian/Ubuntu: sudo apt-get install tesseract-ocr

2. Install the package

pip install ytvideo2pdf

3. Run the CLI

ytvideo2pdf --input=youtube --url="https://youtu.be/Z_MLrbI1s2E"

Common usage

Extract from a local folder (expects a single video file in the directory):

ytvideo2pdf --input=local --dir="C:\path\to\video_dir"

Run with a specific extraction strategy:

ytvideo2pdf --input=youtube --url="https://youtu.be/Z_MLrbI1s2E" --extraction=prominent_peaks

Extract a fixed number of frames:

ytvideo2pdf --input=youtube --url="https://youtu.be/Z_MLrbI1s2E" --k=10

Extract frames at explicit timestamps (seconds):

ytvideo2pdf --input=youtube --url="https://youtu.be/Z_MLrbI1s2E" --extraction=timestamps --timestamps="30, 95.5, 120"

What you get

• A PDF file in output/ with the extracted frames.
• A JSON metadata file alongside the PDF (same name, .json).
• Intermediate folders (unless --no-cleanup) for extracted frames and cached objects.

Key features

• Multiple extraction strategies to pick the most informative frames.
• OCR-based signal processing (Tesseract by default).
• Optional caching of processed frames for reuse.
• Optional plots of the OCR signal (for debugging and tuning).
