Why chapters don’t show
The first timestamp must be 0:00, there must be at least 3 timestamps in order, and each chapter must be at least 10 seconds long. If any rule fails, YouTube shows no chapters at all.
In the video’s description, one per line, each line starting with its time, like 0:00 Intro.
YouTube can take a while to pick up a changed description, so check again later. If they still don’t show, paste the description here once more: a first timestamp other than 0:00 or one chapter under 10 seconds is enough to hide them all.
Yes. The free YouTube timestamp generator watches the video and writes chapters that follow these rules.
