🔸 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.
