Oh :eyes: so you mean when the publisher of the video/podcast/song/... defines sections, you could just chop up along those marks?

It’s easier to use time stamps for anchors. Subtitles for example are just text with a timestamp. Breaking up a video in segments is mostly important for handling uploads/downloads of large files (>100MB) especially over slow connections. It also has benefits for CDN caching.

Segments are usually fixed byte size or duration to optimize for storage and delivery, anchors/chapters are not. They need to be defined separately.
