The classes WireTapClipFormat and WireTapAudioClipFormat are used to specify a number of properties of a clip. Instances of these classes can also have XML metadata associated with them. The metadata is used for free-form or specialized data.
The representation of a clip closely matches that of an Open Clip.
wiretap_get_metadata -s SourceData -n <path_to_your_CLIP_node_>
displays all the metadata available, of which the most relevant parts are described in the Open Clip description.
The XML stream of a CLIP node returns the sequence structure and characteristics of that node.
