Part 1: What is MP4?

What is MP4? MP4 is a standard digital multimedia container format. The code type is MPEG-4 (Moving Picture Experts Group), a compression standard used for audios and videos, which is specified by International Organization for Standardization (ISO) and International Electro-technical Commission (IEC). MPEG-4 file format is mainly used in Internet, disc, audio messages, video calls and telecast.

MP4 is considered to be a digital media container format – basically a file containing a set of data that has been compressed. Due to the high compression used in MP4 videos, MP4 is smaller than other video formats. Moreover, almost all of the original quality is preserved when the MP4 file is compressed. This makes MP4 video a very portable and network friendly video format.
