The introduction of MXF file: MXF (Material eXchange Format) is a "container" or "wrapper" format which supports a wide range of 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. –from wikipedia
The MXF file format is used by digital audio and video programs, which contains the recorded audio and video data as well as metadata that describes the media store in the file. The MXF metadata may carry information about:
• The file structure
• The body contents - e.g. MPEG or DV, 525 or 625, etc.
• Key words or titles
• Reference numbers
• Editing notes
• Location, time, date and version number
The list may be endless. In extreme cases files may contain more metadata than video or audio content! However, the efficient implementation of metadata is seen as the key to material management. The metadata may be filtered to hold only what is relevant to the particular operational environment, thereby cutting possible meta-mountains.
It has no need to carry the editing 'EDL' information. If the content has come from an edit session, the editing data will have been used to conform the material and so has no further use here. Should full edit archiving be required it should be performed as a part of the editing operation, before outputting to MXF.
MXF files were designed to streamline workflows between different platforms, such as cameras, digital editing equipment, and servers. The file format adopts a subset of the Advanced Authoring Format (AAF), which was designed to help standardize the interchange of video between multiple vendors and platforms.
