Clip
v1.5
Clips are instances of animation and shape actions (ActionSource), audio
and image sources (Source) and compound clips (ClipContainer).
You can check to see the clip type (such as an audio clip) using the SIObject.Type
property which returns one of the values contained in the siClipType enum.
This object also provides access to clip features such as its timing (TimeControl),
any links to other clips (ClipRelation), and any applied effects
(ClipEffect). In addition, you can get the underlying source on which this
clip is instantiated (the Source object via Clip.Source)
or the elements of that source (using either the MappedItem object via
Clip.MappedItems or the AnimationSourceItem object via
ActionSource.SourceItems).
Important: While the Clip object represents compound, audio, and image clips, not all Clip
methods and properties are available for these types. For example, the Clip.MappedItems
property will fail and report that it is not implemented for these clip types (ie., returns
E_NOTIMPL).
Tip: There is no function in the object model to create clips from sources, but you can use
the AddClip command, which returns this object. To access existing Clip
objects, you can get the ClipCollection on the Mixer via
the ClipContainer.Clips property.
