Opening MPV4 files

What is the .MPV4 file type?

The filename extension .mpv4 belongs to a family of extensions related to the MPEG-4 multimedia container format. MPEG-4 is an internationally standardized method of compressing audio and video data developed by the Moving Picture Experts Group (MPEG), while MPEG-4 Part 14, or MP4, defines a standard container file format for multimedia content encoded with the MPEG-4 codecs. The only standard extension for the MP4 files is .mp4.

Most commonly, the .mpv4 file is a standard MPEG-4 container with a non-standard extension (.mpv4). The purpose of using non-standard extensions like .mpv4 is to allow additional non-MP4 content within an otherwise standard MPEG-4 container, or define vendor-specific codec setups. Such files (.mpv4) can be opened by any multimedia player or authoring tool that supports MPEG-4 in general. Certain software, especially on platforms that rely on filename extensions like Microsoft Windows, may require the .mpv4 extension to be changed to a more common one like .mp4.

Apart from that, the .mpv4 extension may sometimes be used interchangeably with the .m4v extension to denote raw, containerless MPEG-4 Visual (MPEG-4 Part 2) streams.
