'''Interoperable Master Format (IMF)''' is a [[Container format (computing)|container format]] for the [[Standardization|standardized]] digital delivery and storage of finished audio-visual masters, including movies, episodic content and advertisements.
In IMF, each kind of [[Essence (media)|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”)<ref name=":3" />. This component-based approach allows the large media files to be reused across multiple playlists, each representing a different version of the content..<ref>{{Cite web |last=2018-09-16T11:26:00+01:00 |title=IMF: A gateway to component-based workflows |url=https://www.ibc.org/thought-leadership/imf-a-gateway-to-component-based-workflows/3204.article |access-date=2022-05-20 |website=IBC |language=en}}</ref>

== History ==
The need for IMF arose from various projects in the film and television industries<ref>{{Cite web |title=© 2011 AmberFin Limited Loose Coupling for Multipurpose Distribution Bruce Devlin Chief Technical Officer. - ppt download |url=https://slideplayer.com/slide/7416420/ |access-date=2022-04-01 |website=slideplayer.com}}</ref> that identified component-based working as a more efficient mechanism for handling the very large volumes of very large files created when delivering cinema and television content around the globe<ref>{{Cite web |last=Blog |first=Netflix Technology |date=2017-04-19 |title=The Netflix IMF Workflow |url=https://netflixtechblog.com/the-netflix-imf-workflow-f45dd72ed700 |access-date=2022-04-01 |website=Medium |language=en}}</ref>. With help from the Entertainment Technology Center<ref>{{Cite web |title=ETC |url=https://www.etcenter.org/imf-version-1-0-launches/ |access-date=2022-04-01 |website=www.etcenter.org}}</ref>, the [[Society of Motion Picture and Television Engineers|SMPTE]] created the first version of the standard in 2013. The IMF User Group (IMF UG) was created by the [[Hollywood Professional Association]] shortly after and the IMF UG fosters active discussions between content owners, technologists, logistics specialists and software providers on best current practice for delivering large volumes of localized content in a resource efficient manner. The IMF UG has created an IMF explainer in multiple languages<ref name=":3">{{Cite web |title=EXPLAINER: Interoperable Master Format (IMF) – IMF UG |url=https://www.imfug.com/explainer/ |access-date=2022-04-01 |language=en-US}}</ref>
