What is mp4?

Film Film Film Group-4 (MPEG-4 or MP4) is a compressed video file that is able to contain a high-quality film in a small storage space. In many ways, MP4 is similar to the film group sound set (MP3), except that it is usually used for video. Many video players are compatible with MP4 files and incompatible programs can read files using a tool called codec. To overcome this problem, the weight of the information contained in the audio or video file is translated into a more concise and portable language. This language then becomes known as the "file format" and if the program is used, it is able to read this file format, then any file in this format can be translated and then played.

Simple analogy would be the term "MP4" itself. To help the Fast Communication, the phrase of the Film Films Expert Group-4 was compressed into a shortened version. People who are familiar with the subject withThe subject hears the shortened version of "MP4", but fully understands that it refers to the fourth format of the Expert Motion Pictures file group. The MP4 format basically does the same with video files and compresses information into a format that can be read and processed faster.

The word "codec" comes from the words "compression" and "decompression", which is basically what they do. The MP4 codec that is used in the file is needed to teach any incompatible player. These codecs are generally distributed in packages, making it easier to maintain current file formats, as users can cover all the most common formats with one download.

The

MP4 format is more efficient than its predecessor, an expert on Films Group-2 (MPEG-2) and is very widely used. Format allows users to "stream" video content from the Internet, play video content while the file downloads to your computer's hard drive. The format has made video files much easier to transmissible that it is common for portable devices to store video clocks thanks to file compression.

Generally, MP4 files will be marked by extension ".mp4" at the end of the file name. However, there are variations. Letters "A" and "V" can be added to enter audio and video files.
