Track Types
The timeline supports nine track kinds:
| Track Kind | Description |
|---|---|
| Video | Primary screen recording content |
| Audio | Audio playback tracks |
| Sound Effect | Background music or sound effects |
| Overlay | Graphical overlays (text, shapes, images) |
| Captions | Subtitle and caption tracks |
| Metadata | Non-visual metadata (markers, annotations) |
| Effect | Video effects including Auto Zoom |
| Special Effect | Reserved for special effects |
| Camera Layout | Camera frame layout configuration |
Grouped Recording Tracks
When "Group Recording Tracks" is enabled, related tracks are collapsed into a single "Recording" row:
- Screen video + Camera overlay + System audio + Microphone audio → one grouped header
Overlay and sound effect tracks are packed into multi-lane groups to avoid visual overlap.
