How to Add Chapters to a YouTube Video (and Why They Don't Show)
To add chapters to a YouTube video, open the video in YouTube Studio, go to the description, and type a list of timestamps with a title after each one, starting with 00:00. Then click Save. YouTube's Video Chapters help page sets the rules: the first timestamp must be 00:00, you need at least three timestamps, they have to be in ascending order, and each chapter must be at least 10 seconds long. We checked that page on November 5, 2026.
If your timestamps follow those rules and chapters still don't appear, the cause is usually your channel's feature access or a strike, not the formatting. Both are covered below.
How to add chapters to a YouTube video in YouTube Studio
These steps are from the chapters help page:
- Sign in to YouTube Studio.
- Select Content from the left menu.
- Click the video you want to edit.
- In the Description box, add your list of timestamps and titles.
- Click Save.
This works on videos you published months ago as well as new uploads. You don't need to re-upload anything. If you're uploading a new video, you can paste the chapter list into the description on the Details screen during upload. Our guide on how to upload a video to YouTube walks through the rest of that screen.
What the timestamp list looks like
Put each timestamp on its own line, with the chapter title on the same line:
`` 00:00 Why this city vanished 01:12 The first warning signs 04:40 The night of the flood 09:05 What the divers found 13:30 What we still don't know ``
For videos over an hour, add the hour: 1:02:15 The final theory. Google's video structured data guide describes the same format for YouTube descriptions: hour, minute, second, the label on the same line, one timestamp per line, in chronological order.
You can put the list anywhere in the description. We put it under the first two or three lines, so the opening still says what the video is about.
The rules for YouTube chapters
Here are the rules from YouTube's help page, with the mistake each one usually catches:
| Rule | Common mistake |
|---|---|
| First timestamp is 00:00 | Starting at 00:05 or 0:30 because the intro "doesn't count" |
| At least three timestamps | A short video with only an intro and one section |
| Ascending order | Copying a list from an old draft after re-editing the video |
| Each chapter at least 10 seconds | A quick "Subscribe" or "Sponsor" chapter that runs 6 seconds |
If even one rule fails, YouTube ignores the whole list and the progress bar stays in one piece. So when chapters don't show, check these four things first. A tiny chapter near the end is easy to overlook in a long list.
The help page also says manual chapters override automatic ones. If you type your own list, YouTube uses yours.
Can you add chapters to a YouTube video on your phone?
YouTube's chapters page only gives computer steps. On Android, YouTube's Navigate YouTube Studio page says the YouTube Studio app's Content tab lets you "edit video details," which includes the description. Since chapters live in the description, you can open the video there, paste the timestamp list, and save.
Typing timestamps on a phone keyboard is slow and easy to get wrong, though. If you can, write the list on a computer, where you can scrub through the video and check each start time.
Automatic chapters
YouTube can also create chapters for you. Per the help page, "Allow automatic chapters" is checked by default for new uploads. You'll find it in Studio by opening the video, clicking Show more, and looking under Automatic chapters.
Two limits are worth knowing. YouTube says not all videos are eligible for automatic chapters, and eligible videos may still not get them. And you don't choose the titles. For a channel that relies on search, writing your own titles is the better choice, because you can use the words viewers type.
To turn automatic chapters off:
- One video: open it in Studio, click Show more, clear "Allow automatic chapters," and click Save.
- All future uploads: go to Settings, then Upload defaults, then Advanced settings, and clear "Allow automatic chapters (when available and eligible)."
Why YouTube chapters aren't showing
If the formatting is right, the chapters help page lists three other reasons:
If you'd rather make videos than read about it, VidPuff turns a title into a faceless video. No waitlist, cancel anytime.
- Your channel doesn't have advanced features. Chapters need access to YouTube's advanced features.
- Your channel has an active strike. Chapters are unavailable while any strike is active.
- The video may be inappropriate for some viewers. Videos flagged that way don't get chapters.
New channels can hit the first one. YouTube's feature access page lists "Add chapters" under advanced features, along with clickable links in descriptions, pinned comments, and applying for monetization. Phone verification only gives you intermediate features. The page says creators with "sufficient channel history" will likely qualify automatically, and you can get access right away by verifying your identity with a valid ID or a video, although it notes that ID and video verification "isn't available to all creators." You can check your status in Studio under Settings, then Channel, then Feature eligibility.
After you save, reload the watch page. If the chapters aren't there, recheck the list against the table above.
Why chapters are worth the five minutes
Chapters show up as sections on the progress bar, so a viewer who wants one part can jump to it instead of leaving. They can also reach Google: the video structured data guide says Google Search tries to show "key moments" in videos and will "prioritize key moments set by you, either through structured data or the YouTube description."
Good chapter titles help here. "Part 2" tells nobody anything. "What the divers found" does. Name each chapter with the words a viewer would search for, and keep them short enough to read on a phone. If you plan your video in sections, your outline gives you the chapter list almost for free, which we cover in how to write a YouTube script.
Chapters won't rescue a weak video. They work best on long videos where people come for one specific part: tutorials, explainers, top-10 lists, and long history or story videos. For other ways to keep viewers watching, see how to get more views on YouTube.
If you run a faceless channel with long documentary-style videos, VidPuff can make the video itself: you type a title, and it writes the script, generates narration, creates a visual for each scene, adds music and captions, and renders a 16:9 video you review stage by stage. Its script sections give you a ready outline for chapter titles, and you add the timestamps in the description as above.
FAQ
How do I add timestamps to a YouTube video?
Edit the video's description in YouTube Studio and type each timestamp with a title on its own line, starting at 00:00. Viewers can click them. If you have at least three in ascending order, each at least 10 seconds long, YouTube also turns them into chapters on the progress bar.
Why are my YouTube chapters not working?
Check that the first timestamp is 00:00, that you have at least three, that they're in order, and that no chapter is shorter than 10 seconds. If all of that is right, your channel may not have advanced features yet, may have an active strike, or the video may be marked as inappropriate for some viewers, per YouTube's chapters help page.
Can I add chapters to a YouTube video after it's published?
Yes. Open the video in Studio, add the timestamp list to the description, and click Save. You don't need to re-upload, and the video keeps its views and URL.
Do YouTube chapters help with SEO?
They can help with how your video appears in search. Google's video structured data guide says it prioritizes key moments set in the YouTube description. Neither Google nor YouTube promises a ranking boost, so treat chapters as a way to help viewers, with search as a bonus.
