I have been curious for a while but haven't asked, but I am wondering what the small marks are in the timeline when watching a movie or show that doesn't have commercials marked in them?
I know the spaces in the timeline (the darker purple colors) in shows that I have commercials marked are just that, the places where commercials exist. They are usually wider than the ones I am talking about though. The ones I am talking about are very small in width and there are usually 5, 6 or 7 of them fairly evenly spaced out. I was thinking maybe they denote a chapter marked in the video but was wondering, if so, what is the purpose for them and how did they get there?
