Is a format established by Japanese companies in 2006. Designed for storage of video in resolution HD. The basis of lay encryption algorithm MPEG-2. Today, there are two HD-resolution videos: 1080p and 720p. This format is positioned as a direct alternative to obsolete DV in the home video recording sphere.
The *.m2v files are normally destined to be multiplexed (muxed), which is the process of adding audio data and perhaps other streams such as subtitles, before use. M2Vs are created by demultiplexing (demuxing) an existing MPEG-2, or by converting another video format to MPEG-2. The file extension m2v is mostly found with SFV Host Files.
