What is Chapter Markers?
Chapter markers are timestamps that split a video or podcast episode into named sections, letting viewers and listeners jump straight to the part they came for.
Updated · Editorial policy
On YouTube, chapters are generated from timestamps written into the video description, with the first one starting at 00:00 and at least three chapters present, each lasting ten seconds or longer. In podcasting, chapters are embedded in the audio file itself or supplied in the feed, and support varies by listening app.
Chapters change how long people stay. A viewer who lands on a 25-minute review and cannot find the pricing section usually leaves; one who can click straight to it often watches that segment and then scrubs back. They also give the search engine labelled sections, which is why chapter titles are worth writing as plain descriptions rather than inside jokes.
Write them from the finished edit, not the script, so the times are accurate. A workable set looks like: 00:00 What this tool actually does, 01:42 Setup and first import, 06:10 Pricing and limits, 11:55 Who should skip it. Keep each title under about 40 characters so it is readable on a phone.
Where Chapter Markers shows up
You will meet Chapter Markers most often while comparing video editing saas - Descript, VEED, Kapwing, and InVideo all deal with it, though not in the same way or at the same price.
