It is not only used to store digital audio and digital video streams, especially those of MPEG, but can also be used to store other data such as subtitles and pictures. As a most modern container format, it allows streaming over the Internet. With the help of a piece of MP4 video equipment, you can change various programs such as MPEG to MP4, ASX to MP4, AVI to MP4 and so on, which can be done very quickly and easily without any effect on the sound quality.
