MP4 (MPEG-4 Part 14) is a video container format based on QuickTime MOV. But unlike MOV, it adds support for other MPEG features. MP4 supports video (MPEG-4 Part 2 and MPEG-4 Part 10/H.264), audio (MP3, AAC, SLS, TTSI, and ALAC), and subtitles (MPEG-4 timed text). It’s this codec combination that gives MP4 its flexibility.

MPEG-2 is a digital video coding format introduced in 1995 and later revised in 2013. It uses lossy video and audio data compressions and is very popular among video hardware, thanks to its low computational complexity. It is also widely used in cable and satellite broadcasting as well as writing DVDs.
