How to generate chapters from subtitles
- 1Paste your .srt or .vtt file into the box on the left.
- 2Choose how often a chapter should start. Five minutes suits most long videos; use one or two for shorter ones.
- 3Copy the list and paste it into your YouTube description, then edit the titles to taste.
Why does the first chapter always start at 00:00?
YouTube only enables chapters when the first timestamp is 00:00. If it is not, none of the chapters appear — not just the first one. The first entry is pinned to zero for that reason, whatever time the opening cue actually starts at.
Where do the chapter titles come from?
Each title is the first sentence spoken after that timestamp, trimmed to 60 characters. It is a starting point, not a finished title — rewrite them so each one describes what the section is about. YouTube also requires at least three chapters.
