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.
KAR is the original format of audio files for creating karaoke, which are formed in a variety of software systems. It has the ability to save not only MIDI file data, but also lyrics. The KAR format is part of the .midi extension. In most cases, they are used as a source for adding special text to regular MIDI files, and they also differ from the Karaoke file. After all, there is no additional track with words that are synchronized with the main melody according to certain algorithms. As a rule, in order to realize the vocal part, you must apply the first track. For a stream of words, a second track is used. This file extension can be obtained using specialized software. But not only. It can also be created using MIDI keyboards that are connected to computer hardware. If there are appropriate plugins, then you can open the KAR file using the Media Player traditional for the Windows operating system. Anyone using the Mac OS platform can play KAR files in the Mireth Technology Music Man karaoke application. But the universal option for this pair of systems is PG Music Band-in-a-Box. This software is the most popular among analogues.
