Detailed Description

A Track is grouping device within the EDL.

The corresponding Placement by which this Track object is refered defines fallback placing properties to be used by all objects placed on this track in case they don't specify more concrete placements. Typically, tracks are used do make default processing pipe connections, define a layer or pan for sound and for for disabling groups of clips. Note tracks are grouped in a tree like fashion.

This Media Object (often refered to as "track-MO") is allways dealt with locally within one EDL. Client code normally doesn't have to care for creating or retrieving track-MO. Rather, it referes to the global track-asset-ID. The same holds true when placing some other Media Object onto a track: the corresponding placement just refers the global trackID, while the builder automatically retrieves the matching track-MO for the EDL in question. If some EDL contains several instances (track-MO) refering to the same trackID (asset), then this causes all objects placed onto this track to be included several times in the resulting render nodes network (possibliy with varying placement properties)
