The Interoperable Master Format (IMF) is a file-based media format for the delivery and storage of professional audio-visual masters. An IMF Composition consists of an XML playlist (the Composition Playlist) and a collection of MXF files (the Track Files). The Composition Playlist (CPL) assembles the Track Files onto a timeline, which consists of multiple tracks. The location of the Track Files referenced by the Composition Playlist is stored in one or more XML documents called Asset Maps. More details at https://www.imfug.com/explainer. The IMF standard was first introduced in 2013 and is managed by the SMPTE.
