What is a "Segment"?
Breve splits your update into "Segments", which are the invidual topics or things you'd like to cover. You can have one Segment per presenter if you'd like, but remember you can also have multiple segments per presenter.
Splitting things up like that makes your updates much more digestible and easier to find later. If I want to find out what the Finance Director said in the update four weeks ago, I can search for the update (or even for the presenter, or something they said!) and go directly to it - no need to try to seek through different videos to find out where it was.
