Track
Object Hierarchy | Related C++ Class: Track
Track
v4.0
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).
/*
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.
