MPEG-4 Video File
MP4 is one of the most popular formats for multimedia storage and distribution. It is a container for processing of wide data range, from text and graphics to sound tracks and video. Also it is able to support high-quality files, such as 3D-graphics or user’s menus. It is provided in two versions: MPV (for audio) and M4A (for video). A less known extension .mpr is being used for ringtones.
MP4 files may be played by a number of programs, including Adobe Flash, Roxio Creator, Nero Multimedia Sulte, and a default plug-in Windows Media Player. They are adapted for Mac OS and supplied by modern portable players.
MP4/MPEG-4 has been widely used since 2001. By its nature, it is similar with MP3 although more technically complex. It involves AAC coding method and complies with the standards of ISO/IEX 14496-1. Video and audio contained in a MP4 file is usually played in real time. Thanks to extra information (e.g. file name or images) it differs significantly from MPEG. Often it is impossible to embed data in such a file without use of separate streams that commentary tracks are integrated to.
Opus Audio File
The format has been created by IETF community for online broadcasting and is being used for lossy compression of audio data. It provides with excellent quality of sound and very good compression level due to the technology of dynamically adjusted streaming. Being a key audio codec of Skype, OPUS is based on the Skype message-transfer algorithms. As a container, they use .ogg extension.
The format uses CELT and SILK codecs, which allow easy change of bitrate within the range of 6-510 Kbit/s. That is why it has gained prevalence in video chats and video conferences, as well as IP translations.
