MXF is a multimedia container format designed for video to be packaged and edited. Such video material contains metadata, audio and video streams, which are encoded for various formats. The MXF extension was developed by the international company SMPTE, a market leader in cross-platform software and hardware solutions. The MXF extension, or Material Exchange Format File, is in most cases used by users who, as professionals, process, store and transmit video and audio information in the television and film industries. Professional camcorders use the same extension for recording. That's why the issue of playing MXF video is especially relevant. An MXF file is an output file when recording video / audio data from a TV tuner or some other hardware and software device. We are talking about devices whose purpose is to convert an analog signal to a digital one, and then process it. This is not to say that the MXF format is also in demand in terms of font in the SimCity 4 game program, which is a city-planning simulator. MXF is good first because it allows you to store multimedia data. Compression is possible, in fact, by any algorithm.
RM is a video file format developed by RealNetworks. It uses the RealPlayer player, that is, a program for streaming audio and video files. The format contains audio and video data or links to streaming, which can be played back as it downloads. The RealMedia Player program was in great demand when they connected to the Internet using a modem, and when there was practically no broadband access to the global network. The large compression ratio of the format provided the opportunity to carry out online transmission of video and audio data. The quality of the output file, as a rule, was low. Today, such files are often used in order to broadcast Internet radio and Internet video. In the .RM format, music and video are found on the global network or on Western cable channels, on Internet radio stations. Support for this format is carried out by such mobile phones and smartphones as Nokia, Ericsson, Sony, iPhone, as well as mobile devices that operate on the Google Android operating system. Files with the extension .RM are compressed using proprietary codecs RealVideo and RealAudio. Individual Real Media files can be played using a VLC media player that partially supports RM files.
