A timeline is a set of timespans describing the timeline. Each timespan describes one segment for one track and channel on the timeline.
Each segment timespan should have the following data:
type must be timelinestart should reference the inpoint on the timelineend should reference the outpoint on the timelineMetadata parameters:
| Parameter | Type | Description |
|---|---|---|
| track-type | String | The timeline track type, e.g. V. |
| track | String | The timeline track for the segment, e.g. V0. |
| z-index | Integer | Z index of the segment on the timeline track, higher number means higher priority. |
| source-file-id | String | Id of the file in AV to use as source. |
| source-asset-id | String | Id of the asset which the source references. |
| source-track | String | The referenced track of the specified source asset. |

| target-track | String | The track which an export targets. |
| source-rate-drop-frame | Boolean | Flag that declares whether the associated video source uses drop frame. |
