YouTube chapters generator and timestamp checker

• Open the video in YouTube Studio and edit the description.
• Add a list of timestamps and titles, one per line, starting with 00:00.
• Include at least three timestamps in ascending order.
• Make every chapter at least ten seconds long.
• Save. Chapters appear on the progress bar once YouTube processes the change.

• The first timestamp is 0:05 or 0:10 instead of 00:00.
• There are only one or two timestamps.
• Two timestamps are less than ten seconds apart.
• A timestamp is out of order or past the end of the video.
• The channel has an active Community Guidelines strike, or the video is not eligible.

Name each chapter for what happens in it ("Setting up the mic", not "Part 2"). Viewers use chapters to skip to the part they need, and Google can show chapter titles as key moments in search results.
