Characteristics and Uses

MXF is an abbreviation for Material eXchange Format. An MXF file is a container of digital video and audio. The standard is defined by the Society of Motion Picture and Television Engineers (SMPTE).

Its development began in the mid 1990s, when it was envisioned a convergence between IT and TV. The main body behind the idea was the Pro-MPEG Forum, who brought into the project vendors, end users and research institutions. In 2004, the MXF file format was ratified as SMPTE S377M standard.

It is an open file format, meaning that the standard is publicly available. It was designed to solve some problems with non-professional formats. For this reason, it was envisioned as a platform-agnostic container, which could wrap existing and future coding format.

The file structure is composed of blocks. Each block contains a header, which includes a signature and other parameters, such as block size. The file is assembled by iterating all blocks until validation files. A MXF file has metadata and timecode support.

A MXF file may contain an Index Table. It is an optional feature, but it is recommended to include it. This table can be segmented, and can be stored before, after or multiplexed with the data segments.

Concerns

There are some interoperability problems, because different vendors implement only part of the standard. Thus, for example in 2005, Sony’s XDCAM and Panasonic’s DVCPRO P2 produced incompatible MXF files, which could only be clarified with dedicated software.

Furthermore, some vendors store the video and audio components in separate files, and use a randomly generated file naming system. This creates problems with fundamental file operations, such as copying, renaming or deleting.

In addition, several MXF export tools don’t have the capacity to add stereo AES files to the MXF container, or to add free-text annotation.

Most of these problems were addressed in the 2009 version of the standard.
