MP4 is actually an encapsulation format, not an encoding format. To put it simply, it is an extension in which the content is mutable.

MP4 was originally an audio format that doesn't have much to do with MPEG-4, just as MP3 has nothing to do with MPEG-3. MP3 is the abbreviation of MPEG-1 Audio Layer 3, while MP4 is MPEG-2 AAC, which is completely an audio compression format.

Extended data:

Characteristics of MPEG-4

1. Different coding algorithms can be used for different objects, so as to further improve the compression efficiency.

2. The objects are relatively independent, which improves the reusability of multimedia data.

3. Allow users to operate on individual objects, providing unprecedented interaction

4. Allow flexible allocation of code rates between different objects, allocate more bytes to important objects and fewer bytes to secondary objects, thus achieving better results at low bit rates.

5. It can easily integrate natural audio and video objects and synthetic audio and video objects.
