Chapter Rail
The long-form progress rail — the whole video's shape along the bottom of the frame. Past chapters ghosted, future ones dark glass, the live one filling in your accent under its name.

What it's for
The long-form progress rail — the whole video's shape along the bottom of the frame. Past chapters ghosted, future ones dark glass, the live one filling in your accent under its name.
Reach for it when
- Documentaries, deep dives and anything past fifteen minutes
- Multi-part explainers where structure is the reason people stay
- Long interviews split into named segments
How it plays
It answers the question a long-form viewer actually asks, which is not "what is this about" but "how much of this is left". Export one per chapter and let each freeze under its segment; the live segment fills to where you set it and stops, because a full segment says the chapter is over while you are still talking.
Not the right pick when
Short-form of any kind — there is no structure to map. Use the Step Marker for a simple position chip.
The GLASS family
GLASS panels are frosted dark — translucent charcoal with a blurred edge and a hairline border. They sit on darker, contrastier footage: night streets, studio setups with a lit subject on a dark ground, gameplay, screen recordings. On a bright white kitchen they vanish, which is exactly why FROST exists.
