They designed MPEG-1 to compress VHS quality raw video and CD audio at up to 1.5 Mbit/s. It is the world’s most popular and widely supported video without much loss of quality. It is one of the audio formats.

They also designed MPEG-2 to compress video and audio to produce high-quality video and was chosen as the ear compression scheme. -Digital TV, satellite TV services, digital TV, DVD video. The MPEG-2 video format is an “extended” version because it can record video/audio at a much higher bit rate (about 6 megabits per second) than MPEG-1. MPEG-2 video data is typically 30 fps with a maximum resolution of 720 x 480.

MPEG video files are widely supported and can be opened using different applications on different platforms such as Windows Media Player, iTunes, QuickTime, and VLC Media Player.

Opening a MPEG file is usually as easy as double-clicking the file and letting the operating system open it. By default, Windows uses Windows Media Player and macOS uses QuickTime.
