Converter WMV to MPEG

WMV is a common video file format developed by Microsoft and designed to store or transfer video data. It takes its name from the abbreviation of the name of the Windows Media Video technology itself, with which the file is encoded. Codecs for WMV format are installed automatically along with any version of the Windows operating system. Playing WMV files is possible on almost any media player. Such files may contain both Windows Media Video video data and Windows Media Audio audio data. The format also supports the use of DRM protections to prevent copying.

MPEG is a special standard for compressing audio files and video files into a different format, which is most convenient for downloading or forwarding, say, over a global network. The specified standard was developed by the Moving Picture Experts Group. It was created by the international organization ISO just in order to develop a standard for the compression and transmission of digital video and audio data. The official designation for this group is ISO / IEC JTC1 / SC29 WG11. The first time she met in Ottawa in May 1988. By 2005, up to 350 people became participants in the meetings. MPEG, that is, Moving Picture Experts Group, consists of 3 components: Audio, Video, System (combining and synchronizing the other two). There are different MPEG standards, which are also called phases: MPEG-1, MPEG-2, MPEG-3, MPEG-4, MPEG-7. According to the MPEG-1 standard, for example, streams of video and audio data are sent at a speed of 150 kilobytes per second. The speed of a single-speed CD-ROM player is similar. Streams are managed by sampling key video frames and filling in areas that change between frames. This standard ensures the quality of the video image is significantly lower compared to the video that is transmitted on the television standard.
