Reference Structure

• Shared fields are documented in BaseClip, Transform, and Style
• Each clip type has its own dedicated reference page
• Examples and usage patterns are documented separately from field definitions

Shared timeline rules

All top-level tracks[].clips follow these rules:

• Clips are ordered by zIndex first

• Then ordered by start

• Total project duration is the maximum actual end time among top-level clips

• For video and audio, source.end affects the effective playable range

• layout.children does not enter an independent nested timeline scheduler
