Material eXchange Format (MXF) is a file format for professional digital video and audio media defined by a set of SMPTE standards.1 A brief summary of MXF
MXF is a "container" or "wrapper" format that supports a number of different streams of coded " essence", encoded with any of a variety of codecs, together with a metadata wrapper which describes the material contained within the MXF file.
MXF has been designed to address a number of problems with non-professional formats. MXF has full timecode and metadata support, and is intended as a platform-agnostic stable standard for future professional video and audio applications.
