What is the MPEG format, what is it for and how is it used?

In the world of audiovisual technology   there are a wide variety of useful formats capable of adapting to what you need visually in your videos.

And since there are more and more advances to improve the way we see things, the truth is that knowing more about these formats is not too much.

This being the reason why we will dedicate an article to talk about what is the MPEG format? What is it for? How is it used? In some cases MPEG is confused with the .MPG file extension , so read on to learn more about this format.

What is the MPEG format?

The MPEG format (M-PEG correct pronunciation), whose initials that refer to Moving Picture Experts Group is the name given to this group of ISO standards for audio and video. The type ISO file has a unique convertibility and is made simple way to other file types such as .exe, etc ..

 

This has a better video quality compared to other formats, so it is always used by Windows, Quicktime, Indeo and others.

What is the MPEG format for?

Much of its ISO focuses on asymmetric file compression. On the other hand, as it is also capable of multiplexing an audio format as well as the visual data of a video. This allows the visualization of an image with sound digitally.

The MPEG format regulates these processes so that they can be carried out correctly avoiding failures at the time of playback. It is a very diverse format and can be similar to MP4 , which is widely used in Windows and is easily reproduced.

In addition, the MPEG format may vary depending on the location you have, so if your geographical area coincides with the European region, the format to use is PAL, but if the country you are in is located in the American region, you must use NTSC.

Despite this, it is still possible to find a way to adapt, for this it is necessary to have a multizone device that allows you to use more than one format with full compatibility.

You will only have to convert the required format and change from PAL to NTSC or vice versa, being very careful avoiding at all costs a desynchronization between the data in the file

How to use the MPEG format?

As mentioned above, this format allows the compression of audio and video data , being able to do so thanks to the fact that its structure includes encoders and decoders that allow transformation. This format allows you to control the decoder and the bit stream.

The latter known as ‘ Transformation Codecs ‘ will be where the video and audio data are stored, but in a fragmented way that will then be used.

Now, this compression format can vary in more than five formats, each better than the other, the best known being MPEG -1, MPEG -2 and MPEG -4.

The MPEG -1 compression format is the one that is commonly used to create videos with moving image and audio, it was the first compression standard that was presented, it includes the MP3 audio format in its data and usually slightly lowers the quality of the videos, but this is hardly noticeable.

The MPEG-2 compression format is the standard for broadcasting video and audio quality. It is capable of supporting interlacing and a high quality resolution, it is often used in DVD, SVCD, CVD and digital television.

The MPEG -4 compression format tends to be used in those videos where there are DivX and Xvid containers This type of video can be played by various players that are suitable for both MacOS and Windows.
