Differences with MP3
It is important not to confuse MP4 with MP3 . While MP4 includes audio and video, the MP3 format is associated with a compressed audio file with signal losses that do not usually considerably affect its quality.
Because MP4 is an audio and video container format that works with different codecs, it can contain sounds encoded in MP3. However, an MP3 file cannot include videos.
In addition to the one already mentioned, among the most notable differences that are indicated between mp3 and mp4 we can highlight the following:
-MP4 offers higher sound quality. This is because, although both compress the songs, in the case of mp3 there is a greater loss of said quality than in the case of mp4.
-The mp4, in addition, it must be emphasized that it has a greater storage capacity. And that is thanks to the fact that it allows the files stored in it to be compressed much more. We are referring not only to songs but also to videos and even images.
-In the same way, you should know that, as a general rule, the aforementioned mp4 accepts files in a greater number of formats than its predecessor.
-In this list of differences we must include that the most modern player usually has a larger screen than the older one.
-Also another peculiarity is that mp4 was created by Apple.

MP4, on the other hand, is also called the portable player of digital multimedia files . Many times these devices are incompatible with .mp4 files; In any case, this name is used to present them as an evolution of MP3 players, focused exclusively on audio.
