Video chapters
Video chapters are labeled sections of a video, each with a title and start time, that let viewers jump straight to the part they want. Chapters usually appear as markers on the player's progress bar or as a clickable list. Chapters can be written by hand or generated automatically by AI that detects topic changes in the transcript.
Why it matters
Chapters help viewers jump to the part they need, which keeps them watching long videos instead of leaving. For courses, webinars and tutorials, they also improve search results, since search engines can link straight to a chapter. They turn one long video into easy-to-scan sections.
How it works
- The video is split into sections, each with a start time and short title.
- Chapters are stored as timestamps in a description, a WebVTT chapters file or metadata.
- The player shows chapter markers on the seek bar and a chapter list.
- Selecting a chapter jumps playback straight to its start time.
How do I add chapters to a video?
Add a list of timestamps and titles, starting at 00:00, wherever your platform reads them. On many sites that is the description; in web players it is often a WebVTT chapters file. Keep titles short and descriptive. Some tools now generate chapters automatically from the transcript, which saves time for long videos. That makes chaptering an entire back catalog practical: FastPix in-video AI generates chapters automatically at $0.0035 per minute of video.
Do video chapters help SEO?
Yes, they can. Search engines can show chapters as key moments in results and link viewers to a specific timestamp. Clear chapter titles also add relevant keywords. Chapters work best on longer videos where viewers want a specific part, such as tutorials, lectures and product demos.
Where it's used
Online learning platforms, corporate training teams and SaaS products add chapters to long lessons, webinars and product demos so viewers can jump straight to the section they need.
Where it usually goes wrong, and how FastPix handles it
Writing chapters by hand for every long video takes time, so large libraries of lectures and webinars often ship without them.
Alongside chapters, the same in-video AI in FastPix can produce a transcript and summary for each video. A back catalog of lectures and webinars becomes easy to navigate without anyone writing timestamps by hand.
By the numbers
- YouTube requires the first chapter timestamp to start at 00:00, at least three timestamps in ascending order, and a minimum chapter length of 10 seconds. (Video chapters, YouTube Help)
