We designed The Chapter Editor tool to make it easier for you to organize your videos into sections, known as "video chapters."
Normally, when you want to add chapters to a YouTube video, you have to manually input timestamps and titles in the video's description box. This can be time-consuming and a bit cumbersome. Alternatively, you can use automatic timestamps, but these can be lousy.
Chapter Editor streamlines the whole process, making it quicker and more intuitive. Just play the video inside your YouTube Studio, pause it at the point where you want to start a new chapter, give that chapter a name, and, if needed, adjust the timestamp. Then, save it and publish the changes.
