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.
ALAC is the format of a small specialized program called an audio codec. Its main task is to compress a file with digital music without losing its quality. The name of the format created by Apple's IT giant is Apple's abbreviation Lossless Audio Codec. This format may also be called ALE (from Apple Lossless Encoder). Files in this format can play devices even with limited computing resources - such as an iPod. When compressing a file in this format, it is approximately 40-60% of the original file. Now almost every multimedia player based on the libavcodec library is able to play ALAC format files.
