Description MPEG-4 - is a compression method specially designed for low-bandwidth video/audio encoding purposes. Videos encoded in MPEG-4 have various media container formats like MP4, Matroska (MKV), AVI, MXF, and QuickTime (MOV). MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.
Technical details Lossy compression is designed to reduce significantly the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. For example, an MP3 file created using the setting of 128 kbit/s will result in a file about 1/11 the size of the CD file created from the original audio source.
