How do I add chapters to a YouTube video?

The steps at a glance

A chapter list is a few lines of plain text. The work is in choosing where each chapter starts and making every time exact:

1. Decide where each chapter starts.
2. Mark the chapters on your timeline.
3. Export the markers from Premiere Pro or DaVinci Resolve.
4. Convert the markers to YouTube timestamps.
5. Check the list against YouTube’s rules.
6. Paste it into the description in YouTube Studio.
7. Check the chapters on the published video.

Step 1: Decide where each chapter starts

A chapter is a place a viewer can jump to, so it belongs where the video changes: a new topic, a new round, a new location, the next step of a tutorial. A new camera angle or a new joke is not a chapter. If nobody would ever want to skip straight to that point, it doesn’t need one.

Put the start where the new part begins on screen, on its first frame. A viewer who jumps there should land on the new scene, not on the last seconds of the old one.

Name chapters with the words a viewer is scanning for: the boss, the country, the recipe step, the game. “Part 3” tells nobody anything. Tutorials are the clearest case, one chapter per step, as covered in editing tech tutorials. If you work from a script, its section headings make a good first draft; the free script length calculator drafts chapters from script sections.

Step 2: Mark the chapters on your timeline

The easiest chapter list is the one that grows while you edit. Drop a marker where each new part begins and type the chapter title as the marker’s name. When the cut is locked, the list already exists, and nobody has to scrub a long timeline hunting for the start of each segment.

• Premiere Pro: add sequence markers, on the timeline rather than on a clip, and name each one with its chapter title. If you also leave notes as markers, Chapter markers for chapters and Comment markers for notes keep the two apart.
• DaVinci Resolve: add timeline markers and put the title in the marker name. Notes can go in the marker’s notes field.
• Any other editor, or by hand: watch the final export once and write the start time and title of each part in a text file, one per line. Chapters that already sit in an old description can be pasted into the checker in Step 4 as they are.

Step 3: Export the markers from Premiere Pro or DaVinci Resolve

Both editors write markers to a file:

• Premiere Pro: with the sequence selected and its markers visible in the Markers panel, go to File > Export > Markers and pick CSV.
• DaVinci Resolve: right-click the timeline in the Media Pool, then go to Timelines > Export > Timeline Markers to EDL. That marker EDL is a separate file from the EDL of the cut itself.

Menu names shift between versions. These are the paths documented on the converter page; if yours look different, search the editor’s help for exporting markers.

Step 4: Convert the markers to YouTube timestamps

Editors count time in timecode (hours, minutes, seconds and frames) while YouTube wants minutes and seconds. Two details make a straight copy wrong:

• The timeline start. Many timelines begin at 01:00:00:00, not at zero. Copy those times as they are and every chapter is an hour late.
• The frame rate. At 23.976 fps, and at 29.97 or 59.94 fps without drop-frame, a timecode “second” lasts slightly longer than a real one, and the gap reaches 3.6 seconds after an hour of timeline. Drop-frame timecode skips frame numbers so it stays close to the clock.

Where a marker really sits in the exported video when the timeline begins at zero:

The free markers to YouTube chapters tool does this conversion for you. Open the Premiere Pro CSV or the Resolve EDL, or paste a plain list, then pick the timeline’s frame rate and start and type the video length so the last chapter gets checked as well. Each time is rounded down to the whole second, so a chapter never starts after the frame you marked. The file is read in your browser and never uploaded.

Step 5: Check the list against YouTube’s rules

YouTube Help (Video chapters, read October 19, 2026) gives three requirements for chapters you add yourself:

• The first timestamp starts with 00:00.
• At least three timestamps, listed from earliest to latest.
• No chapter shorter than 10 seconds.

Lists usually break on something small. The first marker sits after the cold open, so the list begins at 0:42 instead of 00:00. A late trim leaves two markers three seconds apart. A short sign-off at the very end gets its own line and comes in under 10 seconds. Any one of these can keep the whole list from showing. The converter runs the three checks on every list and has a fix button for the rule that fails.

Two limits sit outside the list. YouTube Help says the chapters feature won’t be available if the channel has an active strike or if the content may be inappropriate for some viewers, and that a channel without access to chapters yet should apply for access to advanced features.

Step 6: Paste it into the description in YouTube Studio

The steps from YouTube Help: sign in to YouTube Studio, choose Content in the left menu, click the video, add the timestamps and titles to the Description, and click Save. One chapter per line, time first:

00:00 The new world
01:12 First night
04:35 Something in the cave
09:58 Building the base
14:20 The final escape

For a video longer than an hour, write the hours as well (1:02:15). A list added this way overrides automatic chapters on that video.

Step 7: Check the chapters on the published video

Open the watch page and hover over the progress bar: it should be split into segments carrying your titles. Click three or four chapters, the last one included, and make sure each lands on the right moment. On a long video the last chapters are where a frame rate mistake shows, since the drift grows with time. If no chapters appear, go back to the three rules first. Chapters are one item on a longer list of things to confirm around upload; the rest is in what to check before uploading to YouTube.

Automatic chapters or your own?

YouTube can also make chapters by itself. YouTube Help says the “Allow automatic chapters” box is checked by default for new uploads, that not every video is eligible, and that not every eligible video gets them. When they appear, YouTube picks both the split points and the names.

One of the Rex & Alexa episodes I edited, a 15:39 Natural Disaster Survival video, shows what that looks like. When I checked it on October 19, 2026, its automatic chapters divided it into nine parts with titles such as “Tsunami survival”, “Volcano eruption” and “Earthquake and sandstorm”. In a video built from clear rounds, automatic chapters can do the job. Write your own when the names matter, when a chapter must start on an exact frame, or when the automatic split falls in the wrong place.

To switch them off for one video, open it in YouTube Studio, click Show more and clear “Allow automatic chapters”. To switch them off for future uploads, go to Settings, then Upload defaults, open the Advanced settings and uncheck “Allow automatic chapters (when available and eligible)”.

How I handle chapters on long edits

On a long video, chapters belong at the very end, once the cut is locked, because any trim before that moves every time after it. The advice I give any editor is to put down a named marker the moment a new segment starts, so the list is ready the day the edit is.

The small failures from Step 5 are easy to miss by eye on a long timeline, and they cost the whole list, not one chapter. That is the reason the converter checks every list it builds. On feature-length uploads the frame rate matters most: on a 29.97 fps timeline without drop-frame, a marker two hours in lands seven seconds late if its timecode is pasted straight into the description. If you would rather hand the whole long-form edit to someone, long-form editing is what I do.

Common chapter mistakes

• No 00:00 line. Without it, YouTube ignores the list.
• Writing chapters before the cut is locked. Every later trim shifts the chapters behind it.
• Pasting timecode straight from the timeline. A one hour start or frame rate drift puts chapters in the wrong place.
• Chapters every few seconds. They don’t help anyone jump, and one under 10 seconds breaks the list.
• Vague names. “Part 2” or “Next” gives a viewer no reason to click.

YouTube chapters FAQ

How many chapters does a YouTube video need?

At least three. YouTube Help also asks for the first timestamp to be 00:00, the timestamps to be in ascending order and each chapter to be at least 10 seconds long. The help page sets no maximum, so add a chapter wherever a viewer might want to jump.

Why are my YouTube chapters not showing?

Check the three rules first: a missing 00:00, fewer than three timestamps or one chapter under 10 seconds is enough to stop them. YouTube Help also says chapters are not available on channels with active strikes or on content that may be inappropriate for some viewers, and that channels without access should apply for advanced features.

How do I turn Premiere Pro markers into YouTube chapters?

Select the sequence and use File > Export > Markers to save a CSV. Open that file in a markers to chapters converter, set the timeline frame rate and start timecode, and copy the list it builds into the video description in YouTube Studio.

Why are my chapters a few seconds late?

Usually the frame rate. On a 23.976 fps timeline, or 29.97 and 59.94 fps without drop-frame, timecode falls 3.6 seconds behind real time every hour, so a marker at 01:00:00:00 sits at 1:00:03.6 in the video. A timeline that starts at 01:00:00:00 adds a full hour unless you subtract it.

Do my own chapters replace automatic chapters?

Yes. YouTube Help says adding your own timestamps in the description overrides automatic video chapters. You can also switch automatic chapters off for one video, or for all future uploads in Upload defaults.
