To create and edit chapters:
Navigate to your video and select the video actions menu in the top-left corner next to your video title.
Select Edit chapters.
Name each chapter.
By default, each scene is a chapter. To group multiple scenes into a single chapter, click the arrow button. This will nest the scene under the previous chapter.
To ungroup a scene from the chapter, click the back arrow button. This will make the scene its own chapter.
Press Confirm to save the chapters. Once the video is generated, chapters will appear when hovering over the player timeline in video player.
Notes:
If all chapter name fields are left empty, chapters won't be shown in the player.
If you provide a name to at least one chapter, any chapter titles left blank will be assigned the chapter number as the name.
Edits to chapters will only show up in the player when a video is re-generated.
You can also edit chapters from the generation window.
