What format is MXF?

MXF is the abbreviation of English Material eXchange Format. MXF is a professional audio and video media file format defined by SMPTE (Society of Motion Picture and Television Engineers). MXF is mainly used in media production, editing, distribution and storage in the film and television industry. The standards defined by SMPTE include: SMPTE-377M, SMPTE-EG41, SMPTE-EG42, etc., and are constantly updated and improved.

MXF files are usually regarded as a "container" file format, which means that the MXF file format has nothing to do with the format of the content data. This is due to the use of KLV (key-length-value) triples at the bottom of MXF. Tuple encoding method. MXF files usually include several parts such as file header, file body and file trailer.

MXF is the abbreviation of the English Material Exchange Format (File Exchange Format). The name itself shows that its role is to establish a universal standard for the conversion of different data formats for data senders and receivers. It converts media files in a professional broadcast environment and is essentially a shell format.

Why do you say this? Like the AVI multimedia format of the PC platform, it is a file format that performs moderate compression and packaging of audio and video, between compression and uncompression. But MXF goes beyond the scope of general AVI. For example: MXF is designed to wrap MPEG2 data streams, DV data streams, YUV data streams, PCM audio files, and database files in several formats (synchronous or asynchronous mode).

MXF can process audio, video and database files that package multiple tracks at the same time. It is designed to support both streaming media transmission and file transmission. Therefore, it can improve the network environment that is hindered by the lack of standard file formats.

Actually, before the emergence of MXF, there were similar formats, such as OMF (Open Media Frame). It is a file format that contains multi-track media information, but OMF is more like AVI. Designed for editing, it lacks the network fluidity of MXF.
