MP2 (MPEG Audio Layer 2) is a Moving Picture Experts Group audio format that comes with a .mp2 filename extension. Like MP3, MP2 is a lossy format and is mostly used for sound broadcasting. Because a limited number of audio players support MP2, it’s best to convert it to MP3, which is a universal format.
MOV is a MPEG-4 digital video container format used on Apple’s QuickTime Player. It was developed in 1998 by Apple as the proprietary video format for Macintosh. On top of video data, MOV format can also store audio and text data, such as subtitles. It can open easily on both Macs and PCs, although Windows require 3vix codec.
