M2TS to OPUS

M2TS is a video file format that contains Blu-ray BDAV high-definition HD video. This is video from Blu-ray discs and digital camcorders. The .m2ts extension means “MPEG-2 Transport Stream”. However, it is associated as the narrower container format BDAV, which is the standard Blu-ray format for consumer video discs. The original name for the file type is Blu-ray BDAV Video File. The format was developed by Sony. It arose after the introduction of new Blu-ray media. The audio and video transmission protocol M2TS, i.e., MPEG-2 Transport Stream, was created based on MPEG-2. In fact, this is his advanced modification. The protocol supports error correction if partial data loss occurs. A .m2ts file is a BDAV container that contains digital multimedia data that is compressed by one of the videos available in the H.262, H.264, VC-1 format. And some audio codecs, too. This is Dolby AC3, PCM. There are several video and audio streams in one M2TS file. There are also subtitle tracks that can be selected during playback. Most modern video players support .M2TS format. For smooth playback, you need a powerful computer. Such a video can be edited using the professional program Sony Vegas Pro.

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.
