SPE Video Master Specs SPE IMF Specifications Sony Pictures IMF Process and Specifications Background Information IMF (Interoperable Master Format) IMF is a SMPTE standardized mechanism for the interchange of motion picture content between devices and facilities. An IMF is a collection of picture, audio and text files in a standardized format that have been designed to play together via one or more Composition Play Lists (CPL). The IMF may contain a number of CPLs, each of which is designed to play out a specific version of the content from the same set of files. Therefore, a particular version can be uniquely identified by the CPL that is designed to play it. SMPTE has created a suite of documents that detail the overall specification for IMF, which includes some specific application documents that are particular to certain parameters, such as picture compression. These are listed below in Document References . Our specification adheres to the SMPTE ST 2067-21:2016, Interoperable Master Format Application #2E (extended) standard of the IMF specification, which utilizes JPEG2000 picture compression with specific profiles and details parameters and values for HDR and WCG. CPL Composition Playlist A CPL is a set of xml instructions that directs the playout of image, audio and text assets. CPLs are used to create the version/alpha desired. Multi-component CPLs are common and all CPLs will require one Base picture asset, one Base audio asset, and optionally, text assets such as subtitles and closed captions in order to play out a version of the content. A slate identifying the CPL with the version/alpha of the content may be part of the Base image track file or may be part of a Supplemental image track file. Additional CPLs and Supplemental IMPs (see below definition) will be used to derive the texted, non- subtitled version, textless version, international version, etc. IMP (Interoperable Master Package) IMP refers to a subset of assets from an IMF that are packaged for transport or that sit in a directory on a storage medium (disc, tape, etc). An IMP generally contains a CPL and only the assets required by that CPL. It is also possible to have more than one CPL if multiple versions are being transported. Sometimes IMP and IMF are used interchangeably, but the IMF is the overall collection of assets for a title in the system (think HDCamSR system) and an IMP is a subset of the IMF that is packaged for a specific delivery (think HDCamSR tape). Base IMF Package Base IMF: The Base IMF is the first IMF created with the original version (OV) essence. There is only one Base IMF per title. A Base IMF package contains all elements to play out the original version (OV) of the show and any textless material that may have been created. The base IMF package is referenced and utilized by all other IMF packages that may later be created. It generally contains the OV image track file, textless shots image track file, OV audio files, any subtitles that were in the OV, and at least one CPL. See below for a full description of the contents and formatting of the IMF base package. Supplemental IMF Package (Supplemental IMP) A Supplemental IMF package contains elements that are to be used in conjunction with the Base IMF package. The supplemental package always contains a CPL and CPL slate, and may contain additional essence. There can be many supplemental packages for a title. If there is additional essence, the CPL is designed to play this additional essence in conjunction with the Base IMF. For example, a supplemental IMP could carry foreign inserts, foreign dubbed audio, a slate and a CPL to play them, and could be used in conjunction with the essence in the original version (OV) IMF to play out a foreign localized version. A supplemental IMP may instead contain only image, audio, text inserts and a CPL, which may be used to play out an Extended Version, or may contain only a CPL and Slate, which may be used to play out a specific edited version. It may also be designed to create a territory-specific version that omits certain sections of the original version, in which case may not contain any new essence, just a CPL that instructs a versioned playout of the Base IMF and a CPL slate. See below for a full description of the contents and formatting of a Supplemental IMF package. JPEG2000 All picture tracks in the IMF will be encoded using JPEG2000 using profiles defined in the section titled IMF Track File Essence Specifications in this document. This is a lossy process and therefore care should be taken to ensure a high-quality VBR encode of the image files. UltraHD / HD The IMF may contain image track files that are UltraHD (UHD) or HD resolution depending on the source material. In general, for theatrical or TV content that was captured and mastered in 4k resolution or above, an UltraHD (UHD) image track file is applicable, whereas for source content that is lower than 4k resolution, an HD image track file is applicable. Both may have extended color gamut information. If the title is to be mastered in high dynamic range (HDR), and the source content is lower than 4K resolution, at the discretion of Sony Pictures it may be up-scaled to UHD. Consult with SPE prior to creating HDR content from material lower than 4K to determine if it should be up-scaled or kept as HD. If an IMF contains a HDR image track file, it must also contain a derived SDR image track file. Consult with SPE prior to creating the SDR to determine the derivation methodology, metadata capture and delivery of ST 2094 metadata. Metadata Per SMPTE ST 2067-21:2016 section 6 Image Track Files , IMF image track files must contain metadata via specific Essence Descriptors in the MXF wrapper, that describes the image content. This includes but is not limited to SMPTE ST 2086 mastering display color volume metadata that specifies the mastering reference display parameters. See SMPTE ST 2067-21:2016 section 6 and ST 2086 for details. Consult with SPE regarding delivery of this metadata if the IMF mastering equipment being utilized does not support the generation of this Essence Descriptor Per SMPTE ST 2067-21:2016 section 7 Composition , MaxCLL and MaxFALL values, calculated as specified, should be included in the CPL as detailed in section 7.2. Consult with SPE regarding delivery of this metadata if the IMF mastering equipment being utilized does not support the generation of these items in the CPL. In the case of an IMF that contains a HDR image track file, it is required that at least one application- specific form of SMPTE ST 2094 image transform metadata be included (e.g. ST 2094-10, ST 2094-30, etc), and in some cases more than one application may be required. Consult with SPE prior to creating an HDR IMF to determine what ST 2094 image transform metadata will be required. As of this writing, there is no specification for carrying 2094 metadata in the IMF itself, so this is to be delivered as a plain-text XML sidecar file until such time as this carriage is standardized in IMF. Base IMF Package Specifications Base IMF Package Contents The Base IMF package should contain the following: Base Image Track File Asset (with slate at head, formatted as below) Base Audio Track File Asset(s) with MCA labels Textless Image Track File Asset (with slate at head, formatted as below) OV CPL (Optional) OV Subtitle IMSC1 Timed Text Track File (if created for the title and if not burned-in to the image) per SMPTE ST 2067-2:2016, section 5.4 Data Essence Track Files (Optional) OV Closed Caption IMSC1 Timed Text Track File, also per SMPTE ST 2067-2:2016, section 5.4 Data Essence Track Files Base Image and Base Audio Track File Head Format Each Base picture and audio track file asset requires a new head format that includes the elements listed below. A visual and audio pop (1 frame of 1kHz tone) is required 10 seconds prior to FFOP in order to provide a visual reference and to guarantee sync. A 1kHz reference tone should be added over the bars & charts on the audio track file asset per the below formatting. There is no actual time code in the IMF. The locations below are master file record time code references. For example, the first frame of the master file at time code 00:59:30:00 becomes frame 0 of an image track file with an MXF track file start of 00:00:00:00. Note- All time code numbers in the below sections are referenced to 24 FPS time code Base Image and Base Audio Track File Tail Format Each Base picture and audio track file asset requires a tail format that includes the elements listed below. A visual and audio tail pop (1 frame of 1kHz tone) at the tail is required 20 seconds after the Last Frame Of Picture (LFOP) in order to provide a visual reference and to guarantee sync. After the tail pop, 5 seconds of black should follow. CPL Slate for Base Package See Appendix B for more detailed information on Base CPL slate contents. A slate is required at the head of each Base image track file as specified by the above formatting that will indicate the content of the image essence. The slate should contain the following data points: GMDM MOVIE OR SERIES TITLE, GMDM TITLE ABBREVIATION, GMDM ALPHA ID, VERSION, EPISODE NUMBER, GMDM EPISODE TITLE, CONTENT TYPE, TERRITORY, FRAME RANGES, PROGRAM RUNTIME, FILE TYPE, RESOLUTION, ASPECT RATIO, COLOR SPACE, ENCODING PROFILE, AUDIO ELEMENT1, AUDIO CONFIGURATION1, AUDIO ELEMENT2, AUDIO CONFIGURATION2, SUBTITLE TEXT, CC TEXT, POST FACILITY, CREATION DATE OPTIONAL FIELDS: REELS, SOURCE BARCODES WORK ORDER PO NUMBER SOURCE IMAGE FILENAME PREFIX (e.g. DPX filename prefix) NOTES Figure 1: Sample Slate Image Textless Track Files Each texted Base image track file requires a corresponding textless replacement. The textless shots are to be in a single track file encompassing all textless replacements (no spacing or black between each shot) formatted as listed below. A slate must be provided at the head of the textless track file per Appendix B. Note: A CPL must be provided in a supplemental package that specifies the location of the inserts in relation to the main program Textless Track File Formatting There is no actual time code in the IMF. The locations below are 24 fps references based on a time stamp that can be set for first frame of MXF track files. For example, the first frame of an image track file is 0 program time, and can be stamped as 00:00:00:00. The textless MXF track file should have a start time stamp of 00:00:00:00 Supplemental IMF Package Specifications Supplemental IMF Package Contents The Supplemental IMF package should contain the following: One Supplemental CPL Supplemental CPL Slate Image Track File Asset (not required if CPL is Picture to Picture) (Optional) Supplemental Image Track File Asset(s) (with slate at head, formatted as below) (Optional) Supplemental Audio Track File Asset(s) with MCA labels (Optional) Supplemental IMSC1 Subtitle Timed Text Track File(s) (Optional) Supplemental IMSC1 Closed Caption Timed Text Track File(s) (Optional) EDL(s) describing the edit points for the supplemental Image, Audio and/or Timed Text Files. EDL files can be delivered in an IMP sub folder labeled EDL . The EDL should be labeled with a description of the content it represents (ie. textless.edl, german_inserts.edl) Supplemental Image and Supplemental Audio Track File Formatting Supplemental Image track files are generally in the form of inserts. Supplemental Audio track files shall be full length, in order to completely replace an audio track in the Base package. There is no actual time code in the IMF. The locations below are master file record time code references. For example, the first frame of the master file at time code 00:59:30:00 becomes an audio MXF track file start of 00:00:00:00. Supplemental Full-Length Audio Track File Format A CPL must be provided that specifies the substitution of the full-length audio track file for the program. If a supplemental audio track file is full length, then it is formatted the same as an OV track file: Supplemental Image Insert Track File Format (e.g. International Localized Inserts) A CPL must be provided that specifies the location of the image inserts in relation to the main program. Image inserts should be placed in a single track file encompassing all replacements (no spacing between each shot) formatted as listed below. A slate is placed at the head of the image insert track file; see Appendix B for slate contents. An additional image insert track file for dubbing cards may also be included in the supplemental IMF. The inserts MXF track file should have a start time stamp of 00:00:00:00. CPL Slate for Supplemental package See Appendix B for more detailed information on slate contents for Supplemental CPL Slates CPL Slates are required per each supplemental CPL in each supplemental package in order to identify the alpha/version that CPL represents**. This slate must be included as the first image sequence in the supplemental image track file as described in the supplemental IMP definition above. If there are no supplemental image track files in the supplemental package, then the CPL slate is its own track file. The CPL slate should be the same duration as and play in place of the picture source file slate. Therefore, the CPL slate will be the one that is visible when played in real time. **Note that Picture to Picture CPLs will not contain this slate. The slate information can be placed in the CPL Annotated Text field. EDL (recommended) If an insert CPL cannot be created, a CMX3600 (File32) EDL should accompany the IMF as a sidecar in order to provide a TC location reference for accurate insert placement. The EDL should include four seconds of textless slate, three seconds of black, and all picture inserts. The destination TC represents the appropriate insert locations relative to the texted program.

In most non-theatrical contexts that we service today, there is only one basic display format. Whether HD or UHD, the display is 16x9, or 1.78. Thus, these variants of the basic aspect ratio describe how various products (standard definition television, silent, sound, widescreen, anamorphic and 70mm features, as well as contemporary productions) are formatted within the 16x9 display to retain their compositional integrity. We may deploy other aspect ratios, either exceptionally or with the introduction of a new format, but these eleven characterize the presentation of most of our product to date. 16x9 133SM - 1.33:1 Side-Matte ( Side-Matted is also referred to as pillar-boxed ) is used by late silent features and standard definition television. Library sound features (pre-1952) re-mastered at 2k have also generally been manufactured in 1.33 aspect ratio. 16x9 137SM - 1.37:1 Side-Matte is the Academy sound aperture standard. Legacy sound features pre- 1952 and re-mastered at 4k are manufactured in 1.37 aspect ratio. 16x9 166SM - 1.66:1 Side-Matte is the flat (spherical) presentation format for the most common post- 1952 European widescreen flat format (equivalent to 1.85 in US). 16x9 - 1.78:1 Full Frame is the native aspect ratio of HD and UHD.

The actual SMPTE standard, modified from 2.35 in 1970, is @2.3976:1, but is frequently referred to as 2.40 for convenience. Modern data-centric productions are often formatted for 2.39 display and generally achieve a 2.39 picture by non- anamorphic means. The DCI standard for cinema projection is 2.39:1. There is widespread use of the Published: 09-06-2018 40 SPE IMF Specifications v2.1 colloquial 2.40, and some products are actually physically formatted in a 2.40:1 aspect ratio, such as Blu- ray disk masters and Blu-ray disks. 16x9 240LB 2.40:1 Letter-Box It is important to correctly document whether a product is 2.39LB or 2.40LB. 2.39:1 is the ratio of modern (1971-present) anamorphic widescreen features.

This ratio is only used by a few Columbia films such as The Long Gray Line, and it disappears completely after 1959. Anamorphic widescreen is more commonly 2.35 or 2.39. Appendix D Determining RFC5646 Language Codes The RFC5646 Language code is constructed by concatenating two codes: The ISO 639-1 Language Code and the ISO Alpha-2 (ISO 3166-2) Territory code. These are separated by a hyphen as follows: <639-1 code>hyphen<alpha-2 code> For example, for US English, the 639-1 Language code is EN and the alpha-2 country code is US , so the RFC5646 code is: EN-US Please access the following links to access the 639-1 code and alpha-2 code: 639-1: http://www.loc.gov/standards/iso639-2/php/code_list.php (use the 639-1 column) Alpha-2: http://data.okfn.org/data/core/country-list For major reference, see the following: https://tools.ietf.org/html/rfc5646 Published: 09-06-2018 42 SPE IMF Specifications v2.1 Contact Info: Brian Vessa Mastering Brian_Vessa@spe.sony.com Michael Friend Data Archives Michael_Friend@spe.sony.com Bill Baggelaar Technologies Bill_Baggelaar@spe.sony.com Greg Geier Operations Greg_Geier@spe.sony.com David Deelo Technology & Engineering David_Deelo@spe.sony.com
