Interoperable Master Format
Interoperable Master Format (IMF) is a container format for the standardized digital delivery and storage of finished audio-visual masters, including movies, episodic content and advertisements.
In IMF, each kind of essence (video, audio, subtitles, etc.) is stored in individual media files (“Track Files”) and the instructions for synchronizing these media files are stored in a separate playlist file (“Composition Playlist”). This component-based approach allows the large media files to be reused across multiple playlists, each representing a different version of the content.
The IMF family of standards, ST 2067, is maintained by SMPTE. Its first edition was published in 2013.
IMF is closely related to Digital Cinema Package (“DCP”), leveraging several of the same standards for packaging and architecture.
The core of IMF is the Composition, illustrated in the first image, which consists of a single Composition Playlist and a collection of Track Files. Each Composition corresponds to a single audio-visual master.
Each Track File contains a specific essence corresponding to a single aspect of the presentation. Track Files are both organized and limited by parameters such as resolution, color space, frame rate, audio sound field, etc. Track Files of disparate parameters may not be mixed in a Composition. Track Files use a constrained version of the MXF OP1a format Material Exchange Format
The Composition Playlist is an XML document. It assembles the Track Files onto virtual tracks that are synchronized onto a timeline. It also contains metadata associated with that timeline.The combination of a Composition Playlist and the Track Files it references is called a Composition.
Each Composition represents a different version of an audio-visual work. Separating the Composition Playlist from the Track Files allows reuse of Track Files across multiple Compositions, as shown in the reuse example diagram.
