What is the difference between .avr and .mpeg-2?

Description: The AVR (Audio Visual Research) file format is a proprietary audio format developed by Audio Visual Research for use on Macintosh computers. It was primarily used in older Mac operating systems and is less common today. AVR files were designed for storing digitized audio data, often used in conjunction with early audio editing and processing software on the Mac platform. This format allowed for the storage and manipulation of various types of audio information, making it a useful tool for researchers, musicians, and audio engineers during its time of popularity.; Video file encoded with the MPEG-2 codec, which is mainly used for over-the-air, satellite, and cable digital TV signals and DVD video; uses lossy compression for audio and video to significantly reduce the size of the video data; not as efficient as the H.264 format.
