MXF (Material Exchange format) is a file format used to exchange program footage between a server, a tape stream device, and a digital device. The content of the MXF can be a complete program, or it can be a complete package or sequence. The basic mechanism for cutting between sequential and audio cross gradients in a file. In this way, the sequence can be integrated with the program. MXF is self-contained and contains all the content so that no additional material is required.
MXF the video, audio and program data, such as text, and the original data bundled together, and put them in a package. It is itself based on flow, with ontologies and some original data. It contains a series of video frames, each video frame sequence is complete with associated audio, and fundamental data (essence), as well as based on the original data frame. The original data generally consists of the time code and file format information of each video frame. This arrangement is also common in interleaved media files.
The file ontology can consist of several different types of material, including MPEG,DV and uncompressed video and audio, and it also uses the SMPTE KLV data Coding System, which has the advantage of being recognized as a standard.
