Takes a Bilibili video URL and generates a complete LaTeX course note with a compiled PDF. The workflow handles Chinese lecture content end to end: it falls back to Whisper when CC subtitles are missing, prompts you for cookie auth when HD frames are login-gated, detects multi-part videos and asks which segments to process, and extracts key frames at the highest available resolution. The output includes the original video cover on the front page, proper section structure, formulas and diagrams as figures, and a final synthesis chapter. It's explicitly designed to rewrite subtitle dumps into actual teaching flow rather than chronological transcription, which makes the difference between a decent reference and something you'd actually want to read.
