Timeline
The time source that connects the authored script to an actual performance. Captions, word-triggered graphics and coverage all resolve against it.
Definition
A Timeline is built from normalized takes that have been aligned to their script segments. It is the bridge between the two coordinate systems a spoken video has: words in the script and positions in the media.
Why it matters
Because tracks resolve against the Timeline rather than against hard-coded seconds, re-recording a line moves the captions and inserts with it. A purely visual animation can use the same Timeline with an explicit end and no takes.
Where it shows up in Hypit
Timeline is assembled by @hypit/timeline-author@1 after each take has been normalized and aligned; film and track declarations take it as a required input.

常见问题
Is the Timeline measured in seconds or words?
Both are available: events can use seconds or frames, and spoken work can address script selections and moments.
Does a visual-only video need one?
It uses the same Timeline, just with an explicit end and zero takes.
What feeds the Timeline?
Normalized, aligned takes — each one is already semantic before assembly.
