Downloading Educational Playlists for Offline Study

Some of the best free education on the internet lives as YouTube playlists — MIT OCW, Khan Academy mirrors, Fireship's series, freeCodeCamp marathons. Archiving them is a valid, respectful use of the medium as long as you respect the creator's licensing.

Before downloading, check the channel's about page. Many educators explicitly permit personal offline use; some ask that you link back if you redistribute clips.

For heavy note-taking, MP4 at 720p is the sweet spot — you can scrub the timeline, pause on slides, and rewind exact seconds.

Consider chaptering. Long lectures often carry chapter markers in the source. Preserve them via M4V or MKV to keep in-video navigation.

A little organization saves hours later: one folder per course, playlist order in filenames, and a plain-text index of what you've watched.
