How do YouTube chapters work?

Include timestamps in your video description starting with 0:00. YouTube automatically creates clickable chapters in the video timeline.

Do I need to start with 0:00?

Yes. YouTube requires the first timestamp to be 0:00 for chapters to work. The tool enforces this.

3-10 chapters is typical. Each chapter must be at least 10 seconds long. Too many chapters can overwhelm viewers.
