You add manual chapters by putting timestamp-and-title entries in a video’s description in YouTube Studio. Start at 00:00, list at least three timestamps in ascending order, and make each chapter at least 10 seconds long; meeting those formatting rules does not guarantee YouTube will display chapters.
After you save, check the video itself and separate formatting mistakes from eligibility or product behaviour. YouTube’s own Video chapters help page is the authority for requirements and access notes; interface labels can change over time.
What chapters do for viewers
Video chapters divide a video into named sections, each with its own preview on the progress bar. A viewer can jump to a relevant part rather than scrub through the entire recording. That is useful for a tutorial with distinct steps, a long interview, a service recording, or a music video with clearly labelled movements.
A chapter title is a navigation promise. If you label a section “Materials”, that point in the video should actually show or discuss the materials. Use concise wording that makes sense without the surrounding description, and choose boundaries that match changes in the content. Chapters do not change the video file or replace its description; they are a way to make the existing video easier to navigate.
For a long replay or a collection of recurring segments, consider whether the labels reflect the structure viewers actually encounter. If the video is part of a continuous channel, advice on planning rotating video blocks may help you organise the material before you publish it. Chapters are most useful when a viewer can predict what lies beyond a boundary from its title.
Open the video in YouTube Studio
Sign in to the YouTube account that manages the video and open YouTube Studio. In the left-hand menu, choose Content, then select the video you want to edit. Studio may present buttons or panels differently on mobile and desktop, but the job is to reach that video’s details and edit its description.
Before changing anything, make sure you have opened the intended upload. This matters when a channel has several versions of a recording, a scheduled upload and a live replay, or a test video with a similar name. Check the title and thumbnail in the selected video’s details rather than relying on a browser tab or a remembered URL.
The description is the field for manual chapters. You do not need a separate chapter editor or special software: YouTube documents the workflow as a list of timestamps and titles in the description. Its video settings guidance covers editing details in Studio; consult the current interface if the labels differ from these steps.
Add timestamps and titles to the description
In the description, add each timestamp and its chapter title on a separate line. A simple format looks like this:
00:00 Introduction
00:35 Materials
02:10 Walkthrough
This is a formatting example only. Choose times and names for the actual contents of your video; do not copy the sample labels unless those sections exist. Each timestamp marks the start of a chapter, and the title tells the viewer what begins there. Keep the timestamp at the beginning of the line, followed by a space and a short title.
If the description already contains useful information, retain it and place the chapter list where it is easy to find. The chapter entries belong in the video description, not in a pinned comment, title, or channel description. YouTube’s upload guidance describes the details and description fields used when publishing; for an existing upload, edit the corresponding description in Studio.
You can draft the list outside Studio first, especially for a long recording. Watch the video and note the actual start time of each section, then check the proposed labels against the footage. This helps avoid a common practical mismatch: a correct-looking timestamp that lands before the named topic has begun. If you are making an edited recording for a live audience, the separate guide to streaming prerecorded video on YouTube explains the broadcast context, while this page covers chapter entries on the resulting video.
Meet the timestamp and ordering requirements
YouTube specifies several conditions for manual chapters. The first timestamp must be 00:00; there must be at least three timestamps; timestamps must appear in ascending order; and each chapter must be at least 10 seconds long. Think of the timestamp for a new chapter as the point where the previous chapter ends and the next one starts. The intervals between successive starts therefore need to be 10 seconds or longer.
| Requirement | What to check | Example of a problem |
|---|---|---|
First entry is 00:00 |
The list begins at the start of the video | The first line begins at 00:12 |
| Three or more timestamps | Count the timestamp lines | Only two sections are listed |
| Ascending order | Each time is later than the one before it | 03:00 appears before 02:10 |
| At least 10 seconds per chapter | Check the gap to the next timestamp, and the final segment | A new chapter begins five seconds after the previous one |
For example, the sample above begins at zero, contains three timestamp lines and moves forward through the video. It illustrates the documented shape, not a guarantee of display. For a short video, ensure there is enough runtime for three chapter starts and the minimum interval between them; do not add meaningless entries merely to reach the count. The labels and boundaries should still be useful and accurate.
Check the punctuation and digits as carefully as the order. A time that is mistyped, omitted or placed after its title can be hard to interpret and will not accurately mark the section. Follow the time style in YouTube’s documented examples and use consistent timestamp formatting throughout the list. Do not include a timestamp for a point that is beyond the video’s actual duration.
These are necessary formatting checks, not a promise from YouTube that chapters will be visible on every video. YouTube notes that manual chapters override automatic chapters. That means a manual list is the set of chapter entries to inspect when both approaches are in play, but it does not mean that manual formatting overrides every eligibility or display condition.
Save and check the video
After editing the description, select Save and wait for Studio to finish saving. Reopen the details or refresh the page to confirm that the chapter lines remain in the description. If you navigate away before the change is saved, the public video may continue to show the earlier description.
Then open the video’s watch page and inspect the progress bar. Check that the chapter divisions and labels correspond to the times you entered, and try selecting a chapter to confirm it takes you to the intended section. You can also play from just before a boundary and compare the footage with the title. A chapter list that technically meets the count but marks the wrong content is not useful to viewers.
If you have edited an existing public video, allow for the possibility that what you are seeing is not yet the latest state or that the video page needs a reload. First confirm the saved description in Studio, then inspect the actual watch page again. Do not infer that the edit failed solely because one already-open tab still shows an older view.
For a channel that runs a continuous stream, chapters apply to the video or replay YouTube exposes, not to the act of keeping a live channel online. A chapter list will not arrange a stream schedule or create new content boundaries by itself. If you are organising a recurring music channel, the always-on music channel setup guide addresses the broader publishing format; chapter work remains a separate description edit.
Troubleshoot when chapters do not appear
Start with the checks you can verify directly. In Studio, confirm the list is in the description of the correct video and that the change was saved. Then check the first time, count, order and duration gaps against YouTube’s requirements. Correct any failure and save again. This isolates a formatting or editing problem before you investigate anything less visible.
If the list meets those conditions and chapters still do not appear, do not conclude that the timestamps guarantee display or that another creator’s workaround is official policy. YouTube says availability can depend on access and content eligibility. Its help page says not all videos are eligible for automatic chapters, and that not every eligible video receives them; it also identifies channel strikes and content that may be inappropriate for some viewers as restrictions relevant to chapter availability. Review the current official help page for the applicable conditions rather than treating community anecdotes as rules.
Keep manual and automatic chapters distinct while troubleshooting. Manual chapters come from the timestamp/title list in your description. Automatic chapters are controlled by a setting and are generated by YouTube when available. A manual list takes precedence over automatic chapters, so if you have entered manual timestamps, first check that list rather than expecting an automatic set to replace it.
If you want YouTube to try automatic chapters, open the video’s settings in Studio and look for Allow automatic chapters. The exact wording or location may change. You can also opt out for a video or through upload defaults. Having the setting enabled is not a guarantee that chapters will be created: YouTube says availability and eligibility vary. For a current explanation, use the official Video chapters help page, not an unofficial claim about a hidden threshold.
A further access question is whether the channel has chapter access. YouTube’s help page says creators who do not yet have access to chapters can apply for advanced features. Check the current account and feature guidance in Studio and YouTube Help; do not assume an application will be approved or that any particular wait time applies. If your video is eligible and correctly edited but display remains unclear, use YouTube’s official help or feedback route for your account rather than repeatedly changing valid timestamps at random.
Edit or remove chapters
To revise chapters, return to the same video in Studio, edit the description, and save. Change the timestamp if the section begins at a different point, or adjust its title if the content label is unclear. Recheck the entire ordered list after each edit: fixing one time can accidentally make a later entry out of sequence or leave a segment under 10 seconds.
To remove manual chapters, delete their timestamp/title lines from the description and save. If automatic chapters are allowed and available, YouTube may then use its own chapters, but do not assume that it will. If you want to prevent automatic chapters, use the relevant setting in Studio or the upload defaults. These are separate controls: removing a manual list is not the same as opting out of automatic chapters.
You can update chapters as the video’s structure changes, but make sure the description still accurately reflects the published version. For example, if you replace or trim the video, previously accurate times may now point to the wrong scenes. Review the actual timeline and check the public watch page after saving so that a viewer is not sent to a section that has moved.

FAQ
How many timestamps do I need for YouTube chapters?
YouTube’s manual chapter requirements call for at least three timestamps, with the first at 00:00 and the rest in ascending order. Each chapter must be at least 10 seconds long. Follow those rules, then check the result on the video; they do not guarantee that chapters will appear.
Can I add chapters without editing the video itself?
Yes. Manual chapters are timestamp-and-title entries in the video’s description, so you can add them in YouTube Studio without changing the video file. The times still need to match the published video’s actual content.
Why are my timestamps not showing as chapters?
Check that the entries are in the correct video’s description, saved, and meet the first-time, count, order and minimum-length requirements. If they do, review YouTube’s current eligibility and access guidance: correctly formatted timestamps alone do not guarantee display.
Do I have to use automatic chapters?
No. You can enter manual chapters yourself, and those take precedence over automatic chapters. Automatic chapters are optional and depend on YouTube availability and eligibility; enabling the setting does not ensure they will be generated.
