What is a Mp4 File?

Before Understanding mp4 files, it’s important to understand how it did originate MPEG-4 Part 14 or simply what we call it as MP4. Based on Apple’s QuickTime MOV format, but adds support for various other MPEG features. It was released in 2001 but re-released in 2003 that’s commonly known as MP4.

MP4 files are like ‘containers’ which store the data and the program behind them ‘codec’ actually show what is stored. So mp4 files have a very different way of handling data using the codec. They rely on specific codec and then determine the execution of the file. Though there are many codecs but not everything will work with the mp4 players. In order to play a mp4 file, it must have the same codec itself. The most compatible codecs are:

Video — MPEG-4 Part 10 (H.264) and MPEG-4 Part 2.

Audio — MP3, AAC, SLS, ALS, TTSI, and ALAC.

Subtitles — MPEG-4 Timed Text.

This codec particularly H.264 gives MP4 a lot more flexibility than other files. For example, AAC files can be handled by M4A files because the AAC files contain codec that is in M4A. The choice of quality depends on the user and also the codec that supports the individual files.

 Besides audio, MP4 files can also contain video, images, and text. You’ll often see various file extensions that give an indication of the type of data within the container. Here are some of the most common:
