Lines in a YouTube description that start with a time. They become clickable jumps, and they are how chapters are declared.
Also called: 0:00 timestamps, linked timestamps
A timestamp line starts with a time token: 0:00, 1:02, or 1:02:14. A space, then a title. YouTube links the time and, if the list starts at 0:00 and has at least two entries, promotes it to chapters.
Links, emoji, and extra sentences on the same line can break the parse. Keep the line short. Put the rest of the description above or below the list, not inside it.
A description extractor should keep the raw lines and the links. Flattening the description into a single paragraph is how timestamps die. If you only want the chapter list, use the chapters extractor instead.
Generated chapters are a draft you paste back into the description. They are not on the video until you publish them.
