Timestamps break a video into sections (chapters) using captions in the description. They make it easy for users to jump to specific parts of longer videos via the YouTube timeline.
Steps to do this:
✅ Figure: Good example - Timestamps are interactive - Users can easily go to each section of the video by clicking on these links or using the slider
You can go extra and include Chapter Markers (table of contents) on the video frame. This is done in video editing tools.
Users see a new section highlighted in the screen, with an optional subtle sound effect, and a strikethrough on the section that just finished.
✅ Figure: Good example - Chapter Markers are rendered over the video and not interactive - A visual table of content inside the video frame
