MMV is the file extension of an older format used by Sony. MMV files were used to store film material placed on tapes. Such video was generated in MicroMV format. The MPEG-2 codec with a bit rate of 12 Mbit / s was used for this operation. A Sony camcorder was used to record the movies on the cassettes.

MovieShaker software was most often used to edit such files. Currently, this technology is rather unusual and considered obsolete.
