Quick technical overview from macro level It defines several tools that can be used by vendors to construct files in ways that are optimized to the task in hand.
MXF is extremely versatile, being useful for such distinct applications as storage of finalised works, just like a tape streaming, such as edit-while-ingest creation of cuts-only EDLs bundled with the source material or the definition of playlists/EDLs that point to external files, for the simple creation of multi-language versions of a programme.įinally, MXF is efficient, as it was designed with a focus on maximizing the flexibility without compromising the efficiency. This is one of its major achievements as, for the first time, we have a standard way of bundling together all components of a programme, making it simple to interchange rich content. MXF also defines ways of carrying ancillary data, such as timecode or closed-captions, as well as any metadata scheme. What does this mean? Unlike transcoding between, say MPEG and DV, the image quality is not altered at all, allowing the same content to be wrapped with various MXF flavours without the slightest impairment in quality. Furthermore, wrapping the content in MXF does not entail any sort of format conversion: MXF is just a thin wrapper around the original encoding format.
It can also carry uncompressed video or audio (PCM). MXF is not a codec format: it will wrap any existing or future coding format, such as MPEG-2, AVC or MP3, in such a way that it allows generic decoders to access files in a consistent, format-agnostic manner. MXF is an open file format, conceived to act as a wrapper of audio-visual content, including associated data and metadata.
