Specifics and Options

The AMWA develops application specifications (AS) designed for the operational requirements of specific parts of media workflows. Each AS is a constrained version of MXF and is intended to facilitate interoperability between the components and processes in the workflow.

The AMWA specifications:

  • AS-02 MXF for Program Versioning
  • AS-03 MXF for Delivery
  • AS-10 MXF for Production
  • AS-11 MXF for Contribution

AMWA AS-02 supports storage and movement of MXF program components to enable multiple versions and inventories for use in a multi-lingual, multi-delivery media environment.

AMWA AS-03 provides MXF optimized for program delivery and is intended for direct playout from a videoserver.

AMWA AS-10 proposes to detail a constrained MXF OP1a file format to enable interoperation with long GOP encoded video. AS-10 builds on the SMPTE RDD 9. The MXF interoperability specification of Sony MPEG Long GOP products.

AMWA AS-11 specifies 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-11 includes the functionality of AS-03 and extends it to include high definition AVC-Intra and includes explicit support for standard definition D-10 video with AES3 audio (compliant with SMPTE ST 386).

MXF Legalizer is a fully integrated component of CubeWorkflow, but is also available stand-alone with a webservice and a watchfolder interface. A single license is valid for one server, independent of the number of cores. MXF Legalizer uses a hi-speed multi-threaded check-and-rewrite algorithm, to provide compliance for standard conformity and beyond! MXF Legalizer secures conformity with client specific format constrains to increase compatibility.

25/50fps with 8x mono PCM 24 bit 48 kHz SD format: MXF OP1a, IMX/D-10, 50/40/30Mbit/s MPEG2 I-frame only (PAL, 25fps), 1 to 8 PCM audio channels in one AES8 block
