✦ WHY THIS WORKFLOW
Studying on video platforms invites endless algorithmic distraction. Downloading clean, chapter-split, ad-free lectures lets you study deeply completely offline.
Help me build a clean offline study workflow using open-source **`yt-dlp`, `FFmpeg`, and `SponsorBlock`**. Provide:
1) [Clean 1080p Ad-Free Archive Command]: Download at max 1080p (H.264/AAC for universal Apple/tablet playback), remove `sponsor` and `selfpromo` segments via SponsorBlock, and embed English/Chinese subtitles + chapters into a single `.mp4`;
2) [Chapter-Split Command]: Automatically split a 3-hour course video into numbered `01_Section_Title.mp4` files by chapter markers;
3) [Reusable `yt-dlp.conf`]: A commented configuration file so I only need to type `yt-dlp <URL>`.
