This is a video file, which was originally created by MOTION PICTURES EXPERTS GROUP, that is the abbreviation of MPEG. That kind of video has 4 layers so the video file called MPEG layer 4 (MPEG4 or MP4). While making a MP3 file, only 3 layers are being utilized or while converting MPEG4 video into MP3, one layer has been removed so that file called MPEG layer 3 (MPEG3 or MP3).

Best of luck
