Chapter

 Chapters are labels describing specific sections of videos. They're navigable either through the SponsorBlock extension menu, or with dedicated keybinds.

Chapter permissions are given automatically to users with a history of accurate segments on a regular basis.

Specifics

This is an example of connected chapters, marked to the same millisecond (there's no break in between).

• Should be timed precisely, just like any other segment. For more information on this, refer to advice for submitting.
• Use the main language of the video.
• Unlike other categories, start a chapter on the first frame of the respective section without including a buffer. End it on the first frame after the section.
• When a chapter leads into another with no break, the ending chapter should stop on the same frame at the newly beginning chapter, without any gap or overlap.

Exceptions / edge cases

• Do not use chapters in place of other categories.
• Do not add sponsoring brand names in chapters if the video doesn't have a  full video sponsor label.
• Chapters should not mock or fact-check the video creator.
• Chapters should not be used in place of closed captions.
• Chapters are not a replacement for other categories. If a segment fits into another category, it should be submitted as that instead of as a chapter.

Imported chapters

This is the import menu that you use to put in arbitrary text, such as from a document or a comment, to make chapters in a video.

SponsorBlock chapters must be timed to the millisecond (ex: 0:14.195) and not the nearest second (ex: 0:14).

If other viewers in the comment section of a video have already created chapters with timecodes, you can import those through the SB extension menu. To import chapters:

1. Copy the text from the comment.
2. Paste it into the import menu (see the screenshot on the right).

When importing chapters from a YouTube comment or elsewhere, edit the segments before submitting to ensure they're:

1. Timed precisely to avoid frame-flashing or sudden audio cuts when jumping to the beginning of a chapter.
2. Following all the category's rules.
3. Not AI-generated or inaccurate summarizations of video content.
4. Not mistimed, or mixed up during the import process.

Adding chapters to outline an entire video

There's no problem with outlining an entire video by yourself, but it can be quite difficult to do with longer or more in-depth videos, because those tend to require a lot of chapters. You should only outline a long video from start to end if you are sure that you've not created inaccurate or mistimed chapters.

• Longer videos, kind of self-explanatory, require a longer outline.
• More in-depth videos may require more chapters for specific sections.

Be careful when outlining an entire video that you don't break the other rules.

Advice for submitting chapters

While watching a video, after pressing the start segment icon, you can quickly double tap the create segment keybind to stop the currently creating segment. You can also begin a new segment starting point to mark abstract points for chapters without pausing the video. Do not submit them in this state! Use them as a starting guide to further edit the chapters in the submission menu when the video has finished.

You don't have to fully outline a video with chapters, other community members can help with adding chapters as far into the video they feel like watching.
