How it's calculated

Frequently asked questions
Why aren't my chapters showing?
Check the first timestamp is 0:00, there are at least three, each is 10+ seconds long, and automatic chapters aren't overriding them (it can take a little while to update).
Where do I put the timestamps?
Anywhere in the video description, each on its own line. They don't need to be at the top.
Do chapters help SEO?
Yes — chapters can appear as 'key moments' in Google search, and descriptive titles help viewers jump to what they want.
