.m2v
.m2v
`.m2v` is a video file extension associated with MPEG-2 video streams, commonly used in DVDs and some digital video cameras. It contains the compressed video data but not the audio information.
What does .m2v mean?
.m2v is a filename extension that represents a video file format used in MPEG-2 video streams. MPEG-2 is a standard for digital video compression, developed by the Moving Picture Experts Group (MPEG). MPEG-2 is widely used for broadcast television, DVD video, and other applications.
.m2v files are specifically used for storing the video component of an MPEG-2 stream. They do not contain any audio Data; the audio is typically stored in a separate file with the extension .mp2 or .ac3.
Applications
.m2v files are used in a variety of applications, including:
1. Video editing: .m2v files can be used as source material for video editing software. The video can be edited, cropped, and filtered to create new video content.
2. DVD authoring: .m2v files can be used to create DVDs. The DVD authoring software will typically combine the .m2v file with an .mp2 audio file to create a complete DVD video.
3. Video streaming: .m2v files can be streamed over the internet using a variety of streaming protocols, such as HTTP and RTSP. This allows users to watch videos on-demand from websites and other online sources.
4. Broadcast television: .m2v files are used in broadcast television systems, such as digital terrestrial television (DTT) and Satellite Television. The video is transmitted in an MPEG-2 stream, and the .m2v file contains the video component of the stream.
History
The .m2v file format was developed as part of the MPEG-2 standard, which was first released in 1994. MPEG-2 is an extension of the original MPEG-1 standard, and it provides Support for higher-Resolution video and more advanced audio compression algorithms.
MPEG-2 quickly became the dominant video compression standard for broadcast television and DVD video. It is still widely used today, although it has been gradually replaced by newer standards, such as MPEG-4 and H.264.
The .m2v file format is closely associated with the MPEG-2 standard. It is a widely recognized format for storing MPEG-2 video, and it is supported by a wide range of software and hardware devices.
