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 20131. IMF is closely related to Digital Cinema Package (“DCP”), leveraging several of the same standards for packaging and architecture.
