This standard specifies the Composition Playlist (CPL) for the Interoperable Master Format (IMF). The Composition Playlist is a representation of a single version of a finished IMF composition (feature, episode, trailer, advertisement, etc). It contains the information necessary to describe the composition and synchronize its underlying essence, e.g. for playout or transcoding. It is an extensible, human-readable structure designed for file-based operations.
