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.
M4V is a video file format that has been downloaded from the Apple iTunes store. The format contains TV shows, videos, films, music. It looks like a .MP4 file, but it sometimes has copy protection when Apple's FairPlay DRM is used (technical copyright protection). The M4V format, i.e., MPEG-4 iTunes Video File, was developed by Apple. MP4 is a container format. Like the same formats as MOV, AVI, MKV, it provides the ability to combine a variety of multimedia streams into one file. Mostly it is audio and video. In order to play the protected M4V file, the computer must be authorized using the iTunes account from which the videos were purchased. In this case, it can be used in order to buy video. Unprotected M4V files can be played by other video players if the extension is changed from .M4v to .Mp4. Files with the M4V extension contain both sound and video data. You can convert M4V files to MP4 format. In this case, it will be possible to play them on other computers, since the M4V files are protected by DRM. MP4 files, compared to the M4V format, do not allow you to specify partition information.
