Track

Introduced

v4.0

Description

The Track object represents the container of clips used to sequence clips in the ClipContainer. You can retrieve the track object using ClipContainer.Tracks property. A track contains only a specific type of clips; for example, audio clips (where Clip.Type == siClipAudioType) are the only type of tracks found in an audio track (where Track.Type == siTrackAudioType). The base property SIObject.Type returns one of the values contained in siTrackType.

Tracks can only be added using the AddTrack command (there is currently no way to add a track using the Object Model).

JScript Example

/*
This example demonstrates how to create a compound clip from scripting.
It also shows that when retrieving clips from the ClipContainer it only
returns clips that are on tracks nested directly under it.
