AS-07: MXF Archive & Preservation Project Owner: Kate Murray, kmur@loc.gov ​ AS-07 MXF Archive & Preservation Brief Description (pdf) AS-07 MXF Archive & Preservation Specification (pdf) The AS-07 Application Specification specifies a vendor-neutral subset of the MXF file format for the long-term archiving and preservation of moving image and other audiovisual content, including all forms of Ancillary Data and other relevant materials. AS-07 defines a means for the carriage and labeling of multiple timecodes; the handling of captions, subtitles, and Timed Text; a minimal core metadata set; program segmentation metadata; and embedded content integrity data. ​ The AS-07 project is led by the Library of Congress and other members of the Federal Agencies Digitization Guidelines Initiative (FADGI). The main users for AS-07 are archives that maintain audiovisual content for the long term. ​ The specification includes a secondary version (referred to by the former AMWA term shim), intended to serve the most critical current needs of many archives: the reformatting of older analog and digital videotapes and, for some organizations, the encoding and packaging of "live" video streams sent to an archive via a serial interface. ​ The following blog page from a key contributor at the Library of Congress will provide further, valuable insight: FADGI MXF Video Specification Moves Up an Industry organization Approval Ladder ​

AS-10: MXF for Production AS-10 MXF for Production Brief Description (pdf) ​ AS-10 MXF for Production Specification V1.1 (pdf) 2012-12-06_AS-10_Conversation Making our News Business Faster, Cheaper and more Flexible. A Conversation with Turner’s Michael Koetter, Vice President of News Technology Planning & Development, about MXF for Production, AS-10 (pdf, 25k) ​ MXF for Production, AS-10 is an Application Specification establishing a common MXF file format for a typical end-to-end production workflow including camera acquisition, server acquisition, editing, playout, digital distribution and archive. AS-10 was developed at the request of CNN, Harmonic and Sony and aims for backward compatibility with existing MXF based systems & devices that have already been deployed. ​ AS-10 is subset of the MXF format originating from Sony XDCAM HD RDD9 that can be used by all production workflow components without the need to transcode or rewrap. ​ A reference implementation (file creator, validator, golden files) will be made available to AMWA members. ​

AS-03: MXF Program Delivery AS-03 MXF Program Delivery Brief Description (pdf) ​ AS-03 MXF Program Delivery Specification (pdf) The MXF Program Delivery Specification, AS-03, is a vendor-neutral subset of the MXF file format to use for delivery of finished programming from program producers and program distributors to broadcast stations. AS-03 Files are intended to be delivered in their entirety to be cached before playout. ​ AS-03 files contain defined sets of metadata for identification of content and for verification of content versus progam traffic metadata that is delivered separately. ​ The specification can be further constrained by a “shim”. Each shim provides a set of constraints that reduce the range of variability that may be needed in well-defined categories of applications. These categories may address particular type of programming or programming genres, or they may address requirements of particular broadcast station groups, for example defining bit rate, aspect ratio, and sound essence schemes. ​

AS-02: MXF Versioning ​ ​ AS-02 MXF Versioning Brief Description (pdf) AS-02 MXF Program Delivery Specification (pdf) AS-02 addresses the problem of having a common file format in a facility that has to handle many input formats and make many output formats. ​ An AS-02 asset can be used as a master file, and different versions derived as needed. Versions may carry different languages and subtitles, or could carry different language title and credit sequences. The design of AS-02 recognizes that individual facilities are likely to have some variations, specifically in the types of codecs and essence that are allowed. Also, variation is expected in the specific metadata rules and audio channel arrangements. For that reason, the AS-02 specification includes a shim specification that takes the rules of AS-02 and further constrains them for use in a facility. ​ Extra metadata and content that is not MXF-wrapped can stored in the ‘extra’ folder. This could be used for example for caption files, Q.C. reports and scripts. ​
