Overview Document - Interoperable Master Format
|
The IMF is a file-based framework for the exchange and processing of multiple content versions (airline edits, special edition, languages…) of the same high-quality finished work (feature, episode, trailer, advertisement, etc) destined for distribution channels worldwide. Specialization of the IMF Framework designed to meet the requirements of specific domains is achieved through the definition of IMF Applications. Provisions common to all IMF Applications are specified in SMPTE ST 2067-2 (“Core Constraints”), while separate documents contain provisions specific to individual IMF Applications.

Core Constraints
|
This document specifies provisions used by multiple IMF Applications. These provisions include essence and metadata constraints, but exclude image essence constraints, which are specified along with other parameters by each IMF Application.

Composition Playlist
|
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.

Essence Component
|
This standard defines the IMF Essence Component, an OP1a MXF structure for interchange of audio, picture and data essence. It defines data structures for interchange at the signal interfaces of networks or storage media, but does not define internal storage formats for compliant devices or mappings for particular essence encodings. It also defines metadata expressions used to communicate allowable variations in the formulation of an IMF Essence Component.

Common Audio Labels
|
This standard defines Universal Labels, names and symbols for common Audio Channels, Soundfield Groups and Group of Soundfield Groups for the purpose of labeling IMF audio essence. This standard also provides informative guidance on naming additional Audio Channels, Soundfield Groups and Group of Soundfield Groups that may be defined in the future.

Application #2E
|
This specification defines IMF Application #2E. It is a specialization of the IMF Framework. Application #2E is meant for studio applications where a TV or movie title is transformed into multiple content versions (airline edits, special edition, languages…) that are made available to multiple consumer distribution channels (Internet, optical media, broadcast…) across multiple territories and over the span of many months to over a year. It uses image essence coded as a JPEG 2000 codestream and audio essence coded as linear PCM.

|
ST 2067-30:2013
Application #3
|
This document defines Compositions for IMF Application #3, i.e. the parameters of Image/Audio/Data Essences, Track Files, and the constraints of Composition Playlist. It is based on Image Essence coded as a MPEG-4 Visual Simple Studio Profile codestream and Audio Essence coded as linear PCM. Compliant implementations need not implement all formats and format values, manufacturers are encouraged to indicate supported formats.

Application #4 Cinema Mezzanine
|
This document specifies compositions for IMF Application #4. IMF Application #4 is a specialization of the IMF Framework. It is intended for the exchange and preservation of cinematographic content after digital postproduction, either sourced from film or from digital media. In particular, it supports Digital Cinema Distribution Master (DCDM) content as specified in the ST 428 family of specifications. To simplify implementation, IMF Application #4 reuses constraints from IMF Application #2 whenever appropriate.

|
ST 2067-50:2018
Application #5 (ACES)
|
This document specifies Compositions for IMF Application #5. It is a specialization of the IMF Framework. Application #5 targets archival applications where a TV or movie title is to be archived as a single, high-quality set of master files from which one or more content versions can be derived. It features SMPTE ST 2065-1 (ACES) image essence of arbitrary spatial and temporal resolution with individual frames encoded as ACES images. The transformation of Application #5 Compositions to the output formats appropriate for different distribution channels is specified in other documents and outside the scope of this document. To facilitate Output Profile List processing, Annex A defines Pixel Color Schemes, as specified in SMPTE ST 2067-101, for the use with IMF Application #5.

IMF Application UHDTV Program Workflow (AVC)
|
This document specifies a new IMF Application as a specialization of the IMF Framework to improve UHDTV program workflows in broadcasting stations mainly in terms of processing time and storage capacity, enabling late editorial changes to a completed master program file to be carried out efficiently.
The new IMF Application targets UHDTV image essence coded as an AVC stream and audio essence coded as a linear PCM stream with reference to the program exchange standards used by, but not limited to, Japanese broadcasting stations.

Application ST 2019-1 (VC-3)
|
ST 2067-70 IMF Application #7 ST 2019-1 VC-3 – Public Committee Draft (Public CD) Different user groups have manifested an interest in having a broadcast-ready format like VC-3 available to use with the IMF workflows. Having an application that natively uses VC-3 allows to achieve that avoiding need for any transcode operation. This document specifies an Application of the IMF framework specified in SMPTE ST 2067-2. The Application covers usage of the VC-3 codec as specified in SMPTE ST 2019-1. The goal of the public CD period is to encourage implementers to discover any issues with the application as well as to encourage interoperability between implementations. The initial public CD period is anticipated to be 6 months to allow time for preliminary implementations to appear and test.

Mapping VC-6 into IMF>
|
SMPTE is pleased to announce the availability of SMPTE ST 2067-71 Mapping VC-6 into IMF as a public Committee Draft document available on the SMPTE website. This document joins the public Committee Draft of SMPTE ST 2117-10 Mapping VC-6 into the MXF Generic Container and enables the development of MXF and IMF workflows utilizing VC-6 video compression.

Output Profile List
|
An Output Profile List (OPL) defines the transformation of selected virtual tracks of a single Interoperable Master Format (IMF) Composition into deliverables appropriate for downstream distribution channels. This transformation consists of a sequence of parameterized steps, called Macros. This document specifies the basic Output Profile List structures and processing model, independently of the underlying essence kinds.

Building on the pioneering work of SMPTE who created a Mastering Format (IMF) for Feature Films, the DPP and the North American Broadcasters Association (NABA) have collaborated to develop a SMPTE Registered Disclosure Document for an IMF Application based on the requirements common to many in the broadcast and online sector. This SMPTE Registered Disclosure Document is based on the image formats referred to in ITU-R BT.2100 and references SMPTE ST 2067 Interoperable Master Format suite of standards and SMPTE RDD 45 Interoperable Master Format - Application ProRes.
