MXF to OPUS

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.

OPUS is an audio file that is encoded using the Ogg Opus format (lossy coding). It was created for online audio streaming, that is, in order to transmit sound through a global network. The format is being developed by the Internet Engineering Task Force (IETF) and Xiph.Org communities. Applies SILK codecs when used in Skype and CELT (from Xiph.Org), provides support for variable bitrate. Most often, the OPUS codec is used for video conferencing, game chats, VoIP telephony. OPUS is a free audio codec that has international standard status (IETF RFC 6716). Its main advantages are a low coding delay (from 2.5 to 60 ms) and its significant speed, an increased degree of compression of audio data with high-quality sound, as well as support for multi-channel audio (within 255 channels). In 2011, J. Skeglund of Google conducted two series of tests, during which OPUS coding and decoding were compared, taking into account the assessments of experts and ordinary listeners. Studies have shown that OPUS provides stereo music with the same quality as MP3 and better quality than G.719 64 kbps. OPUS offers great streaming capabilities with dynamic tweaking and very low latency. This is always high sound quality and excellent data compression. Full support for OPUS is provided by Mozilla applications. He is the key Skype audio codec.
