The Advanced Media Workflow Association (AMWA) is an industry association focused on the content creation industry's move to IP-based architectures. AMWA promotes industry standards that allow diverse devices to discover and interoperate with each other reliably and securely.[2]

Work

As part of AMWA's collaborative process AMWA specifications are published on GitHub.[3][4]

AMWA's Framework for Interoperable Media Service (FIMS) integrates a common approach to integrate hardware devices and software components in TV production facilities [5] [6]

Networked Media Open Specifications (NMOS) provide discovery, registration and control services for the SMPTE ST 2110 media over IP protocol suite, and other media over IP applications.[7][8]

The Advanced Authoring Format (AAF) is a multimedia file format for professional media creators. AAF provides cross-platform data interchange, designed for the video post-production and authoring environment.[9][10][11]

AAF and Material Exchange Format (MXF) are successors to Open Media Framework (OMF).[10]

History

The AMWA began in January 2000 as the Advanced Authoring Format Association. The organization's name was officially changed in May 2007.[1] The first NMOS specification (IS-04) was published in 2016.
