Most of people heard of MP3s. There may be still some confusion over MP4 technology, how it’s used and what is does.
MP4 is a short name of MPEG-4 Part 14. As this name suggests, it is a format used for encoding digital video files. It was created in 1998 and is now growing everywhere.

Actually, this technology works by compressing the files, making the overall size much smaller, in a similar way to that of MP3 technology. MP3 is very popular in customers and MP4 are set to do the same for the video market.
MP4s are made up of several types of media in what is known as a container format. They allow for video, audio, still images and subtitles to be stored together in a single file and have the capability of including advanced content, including menus, user interaction and 3D graphics.
Earlier video files were very large, making them difficult to work with, but Mp4 has the ability to compress and decompress the files. These work by removing all unnecessary information from each frame of the video, without losing quality of file.
In MP4, video files are downloaded quickly from the internet. The format has streaming capabilities, meaning the video can be viewed as it is downloaded. We don’t need to save to the hard drive. We can play at the same time. Portable MP4 players are one such option as are some DVD players and of course a desktop computer or laptop.
In MP4 player, we can listen MP3 audio files also. Even we can open MP2 file also in MP4. Files associated with MP4s have the extension .mp4 or sometimes .mp4a or .mp4v, the a and v standing for audio and video respectively.

Movies can be downloaded quickly via the internet using the high-speed broadband connections currently available, and watched in the comfort of your own home. Movies and clips can be shared easily via email and other formats. The MP4 technology is used by business sector. Advertising and product promotion is easily incorporated in short videos on websites.
