MXF is a media container developed by SMPTE association for professional use. MXF implements subset of Advanced Authoring Format (AAF) data model and nowadays become a standard in professional non-linear video editing. MXF files can be compressed with almost any codec and easily converted to any popular video format. Worth noting that Sony's, Panasonic's and Canon's implementation of this format carries a lot of incompatibilities, that was a big flaw of this container. These issues were addressed in the 2009 version of the standard.

This format was originally intended for voice compression and is able to change the bit rates of encoded audio data. AMR is actively used for encoding and decoding voice while its being transmitted over network channels. The format allows one to consider network capacity and adapt it to channel loads. Due to this, the voice quality is practically undiminished.
