How to Add Chapters to a YouTube Video

To add chapters to a YouTube video, paste a list of timestamps and titles into the video's description, one per line, starting with 00:00. YouTube's rules, as of October 2026, are that the first timestamp is 00:00, there are at least three in ascending order, and each chapter is at least 10 seconds long.

This guide shows the exact format, the steps in YouTube Studio, the reasons chapters fail to appear, and a free tool that checks your list against YouTube's rules before you publish.

The short answer

To add chapters to a YouTube video, open it in YouTube Studio, add a list of timestamps and titles to the description (one per line, such as 00:00 Intro), and save. The first timestamp must be 00:00, you need at least three in ascending order, and each chapter must be at least 10 seconds long. Your own chapters replace automatic ones.

Key takeaways

• Chapters come from timestamps in the description; there's no separate chapters field.
• Three rules from YouTube Help: start at 00:00, at least three timestamps in ascending order, each chapter 10 seconds or more.
• Chapters you add yourself override YouTube's automatic chapters.
• Write chapter titles as plain, specific labels: they show in the player and help viewers jump.

How to add chapters to a YouTube video, step by step

1. Sign in to YouTube Studio and open Content.
2. Click the video you want to edit to open its details.
3. In the description, add your list of timestamps and titles, one chapter per line, starting with 00:00.
4. Click Save. Chapters appear on the progress bar once YouTube has processed the change.

Here's a list that follows every rule:

00:00 Intro
00:42 What a video chapter is
02:15 The three rules
04:30 Why chapters don't show
06:05 Free checker

You can put the list anywhere in the description, and you can add other text above or below it. Videos over an hour use hours too, for example 1:05:30.

Format details that trip people up

• Put each timestamp at the start of its line, followed by a space and the title. "00:42 Setup" is the safe format.
• Use colons, not dots: 1:05, not 1.05.
• Keep times in ascending order. If you reorder sections in the edit, update the list.
• Use the same style on every line. YouTube's help page writes the first timestamp as 00:00.
• If you trim the start of the video later, shift every timestamp by the same amount. The free chapter generator can shift the whole list by any number of seconds.

You can add or edit chapters at any time after publishing; viewers see the change once YouTube has processed the new description.

YouTube's chapter rules (October 2026)

YouTube's help page on video chapters lists three requirements for chapters you add yourself:

The help page also says not all videos are eligible for automatic chapters, and that channels with active strikes, or videos whose content may be inappropriate for some viewers, don't get the feature. Those limits are about automatic chapters; the three rules above are what decide whether your own list works.

Those three rules are all you control. Any list that starts at 00:00, has three or more ascending timestamps and keeps every chapter at 10 seconds or longer meets YouTube's published requirements for manual chapters.

Why your YouTube chapters aren't showing

Work through this list in order. The first three are the rules YouTube lists:

1. No 00:00 line. Add one, even if it's just "00:00 Intro".
2. A chapter under 10 seconds. Usually the last one, or a short intro. Merge it with its neighbour.
3. Times out of order or fewer than three. Sort the list and add a chapter if needed.
4. Timestamps aren't at the start of the line or are written oddly, such as 1.05 instead of 1:05. Use a colon.
5. The video is new or just edited. Give YouTube a little time to process, then reload.

QuickVeed's free YouTube chapter timestamp generator checks the first four for you. Paste your notes in almost any format, such as "Intro 0:00" or "[1:05] Setup"; it sorts them, writes a clean "00:00 Title" line for each, names the rule any chapter breaks, and can add a 0:00 chapter for you. Add the video's length and it also checks that the last chapter is at least 10 seconds. It can shift every time by a few seconds if you trimmed the intro after writing the list. It runs in your browser with no sign-up.

Automatic chapters vs your own

YouTube can add automatic chapters to eligible videos. Chapters you add in the description take priority over automatic ones. To stop automatic chapters:

• For all new uploads: in YouTube Studio, go to Settings, then Upload defaults, then Advanced settings, and untick Allow automatic chapters (when available and eligible).
• For one video: open the video's details, click Show more, and clear Allow automatic chapters.

Automatic chapters save time, but they often pick generic titles. Writing your own takes ten minutes and gives viewers clearer labels.

Writing good chapter titles

• Keep them short, so they fit on the progress bar on a phone.
• Describe what's in the section: "Setting up the API key" beats "Part 2".
• Use the words people search for. Chapters are text, and clear text helps viewers find the part they came for.
• Skip filler chapters such as "Outro" unless the section is worth jumping to.

Chapter titles also show when viewers hover or scrub the progress bar, so they act as a table of contents. Read your list on its own: if someone who hasn't seen the video can tell what each section covers and where the part they want starts, the titles are doing their job.

Chapter examples by video type

Good chapters follow the structure viewers expect for that kind of video. Here are three patterns you can copy and adjust.

Tutorial (12 minutes)

00:00 What you'll build
00:45 What you need
02:10 Step 1: Set up the project
05:30 Step 2: Add the login page
09:15 Step 3: Deploy it
11:20 Common errors

Podcast or interview (58 minutes)

00:00 Intro and guest
03:12 How she started the company
14:40 First 100 customers
27:05 Pricing mistakes
41:30 Hiring the first salesperson
52:10 Advice for founders

Product review or comparison (9 minutes)

00:00 The verdict in 30 seconds
00:35 Design and build
02:50 Battery life test
05:15 Camera samples
07:20 Who should buy it

These counts are practical guidance, not YouTube rules; YouTube only sets the minimum of three. Put the most useful chapter early when you can: in the review example, the verdict chapter lets people get the answer and stay for the details. If you tease a chapter in the video ("I'll show the errors at the end"), its title should match what you said.

Whichever method you use, write the chapter list before you publish and paste it in with the rest of the description. Adding chapters weeks later still works, but viewers who came early miss them.

Finding the chapter points quickly

The slow part is finding where each topic starts. Three ways to speed that up:

1. Use your script or outline. If you scripted the video, note the time each heading starts while you edit.
2. Read a timed transcript. QuickVeed's Captions & subtitles transcribes the video (1.5 credits a minute, rounded up, so 15 credits for 10 minutes) and lets you download SRT or TXT. Scan it for topic changes and copy the times. You can also upload the SRT to YouTube as captions.
3. Add up section lengths. If you edit in sections, the free video duration calculator totals their lengths, and the timecode calculator adds and subtracts times.

Chapters work well alongside other YouTube text: check your title with the free YouTube title length checker. If you also cut the video into Shorts, see how to turn a long video into YouTube Shorts.

Frequently asked questions

How do I add timestamps to a YouTube video?

Edit the video in YouTube Studio and add lines like 00:00 Intro and 01:30 Setup to the description, starting at 00:00, with at least three in ascending order, each at least 10 seconds apart. Save, and they become chapters.

Why are my YouTube chapters not showing?

Usually the list doesn't start at 00:00, has fewer than three timestamps, isn't in order, or has a chapter shorter than 10 seconds. Fix the line that breaks a rule and save again.

Does the first chapter have to be 00:00?

Yes. YouTube's help page says the first timestamp must start with 00:00.

How long does a YouTube chapter have to be?

At least 10 seconds, according to YouTube Help.

Can I add chapters to a YouTube Short?

YouTube's chapter help page doesn't cover Shorts separately, and Shorts are at most three minutes long, so chapters rarely help. Add chapters to your regular videos instead.

How do I turn off automatic chapters?

In YouTube Studio, go to Settings, Upload defaults, Advanced settings, and untick Allow automatic chapters. For one video, clear the option under Show more in its details.
