It is a container format developed by the Society of Motion Picture and Television Engineers - SMPTE for short. MXF files are used by audio and video applications and can be converted to other standardized formats such as AVI or MOV. To play them, as in the case of other media files, appropriate codecs are required.

The MXF format is designed to improve the efficiency of data exchange between different platforms such as digital cameras, digital editing equipment, and servers. The format is based on a subset of the Advanced Authoring Format (AAF) designed to support the standardization of video exchange across different platforms and hardware vendors.
