MP4 is a popular video format that is widely used to store and distribute videos on the internet. However, some devices and media players do not support MP4 files, which can be frustrating for those who want to play these videos on these devices. MPEG is a more widely supported format that can play on most devices and media players, making it a popular choice for those who need to convert their MP4 videos to MPEG.

FAQ

What is the difference between MP4 and MPEG?

MP4 and MPEG are both video formats, but there are some differences between the two. MP4 is a more modern format that is widely used to store and distribute videos on the internet. It is a more flexible format that can support a wide range of video and audio codecs. MPEG, on the other hand, is a more established format that is widely supported by most devices and media players. It is a more standardized format that is used for broadcasting and DVD production.

Can mp4gain convert other video formats?

Yes, Mp4Gain support all major audio and video formats.

The History of MPEG

Introduction

The Moving Picture Experts Group (MPEG) is a working group of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) that specializes in the development of standards for digital audio and video compression. MPEG has been responsible for some of the most widely used video and audio compression standards, including MPEG-1, MPEG-2, MPEG-4, and more recently, MPEG-H.

Early Years

MPEG was formed in 1988 with the goal of developing standards for digital audio and video compression. At the time, digital audio and video were in their infancy, and there was a need for standardized compression algorithms that could be used across different systems and platforms.

The first MPEG standard, MPEG-1, was released in 1993 and was designed to compress audio and video for CD-ROMs. MPEG-1 was a significant milestone in the development of digital audio and video because it provided a way to store and transmit multimedia content efficiently.

MPEG-2

MPEG-2 was released in 1995 and was designed to provide high-quality video for digital television and DVD. MPEG-2 is still widely used today and is the standard for digital television broadcasting.

MPEG-4

MPEG-4 was released in 1998 and was designed to provide a standard for multimedia content delivery over the internet. MPEG-4 introduced many new features, such as object-oriented audio and video, which allowed for more interactive and immersive multimedia experiences.

MPEG-H

MPEG-H is the most recent standard developed by MPEG and was released in 2015. MPEG-H is designed to provide a more immersive and interactive multimedia experience, with features such as 3D audio and support for ultra-high definition video.

Conclusion

MPEG has played a significant role in the development of digital audio and video, and its standards have been instrumental in the adoption of digital multimedia across different platforms and systems. The use of MPEG standards has enabled the efficient storage and transmission of multimedia content, making it possible to deliver high-quality multimedia experiences to audiences around the world.

Some considerations about MPEG2

The world is in a slow but constant evolution: many times without realizing it, we are abandoning things that we did in the past to adapt to the new times. How to buy film roll boxes, in the corner bracket, to place in the camera. Whether on the camera phone or the digital camera itself, that no longer matters to us. But at that time, at the height of analog photography, it was common to know how to order one type of film or the other, saying for example “ASA 100 film” or “ASA 400 film”. There was another specification, very popular in Germany, DIN, with values ​​as similar as the Celsius and Fahrenheit temperature scales … Looking for an international standardization, the ISO (International Organization for Standardization),

The specifications of film labels were standardized, but the world presented new challenges: computers, increasingly present in our daily lives, brought digitization to the living room or the television: the old VCR gave way to the video player. DVD. Still images and then videos invaded the cell phone. However, to get here, new standards have become necessary over time.

MPEG-2 Video

One of them, older, concerned digital photographic images. The same ISO for film boxes (which also created dozens of other standards) joined in 1986 with the CCITT (Consultatif International Téléphonique et Télégraphique Committee) to create the Joint Group of Photographic Experts, whose work would result in 1994 in the JPEG compression standard. . for digital still images.

Compression is necessary in the digital world to reduce the high volume generated by numerical information resulting from audio and video digitization processes. In this process thousands of samples of each part of the image or sound are obtained, which are then converted into sequences of numbers that represent the brightness / color / sound values ​​of the samples. Then it is necessary to have a storage medium capable of storing all these numbers. Since these media typically do not contain as much information, the compression process comes into play.

And that’s not all: compression also has advantages in video transmission, allowing you to send a signal with better quality, compressed, occupying the same space as a lower quality signal, without compression.

In the JPEG standard, the image is divided into 8×8-pixel squares and by complex mathematical calculations an ‘average’ color is determined for these 64-pixel blocks. This results in loss of detail in compression. The processes in which this occurs are known as “lossy”. There are processes in which there is no loss (‘lossless’), used for example in the GIF standard (Graphic InterFace, developed by Compuserve) to compress photographic images. However, standards such as GIF are suitable for graphics and not for photographic images, because the set of colors treated by them (256 colors) is much smaller than that used in standards such as JPEG.

In January 1988, ISO formed a working group called the Motion Picture Experts Group together with the IEC (International Electrotechnical Commission), generating an acronym that would become well known: MPEG. The group, formed to create international video and audio compression standards, then created the MPEG-1, MPEG-2 and MPEG-4 algorithms that are used today.

The use of MPEG algorithms always involves two phases: the compression phase, where the image and / or audio are compressed, generating content with a smaller total size, ready to be recorded on an optical disc, for example, and the recovery phase of this content, also called expansion, where the original image and / or audio is reconstituted. Compression is done by software called a compressor and expansion by software called an expander. These names have better known synonyms, encoder and decoder respectively. And the set of 2 forms the word codec, short for encoder (encoder) + decoder.

The MPEG standards brought a new philosophy in coding systems, where the encoder process is much more laborious and complex than the reverse of the decoder. Since decoding is simple and fast, it facilitates the proliferation of electronic circuits that perform this process efficiently, making players cheaper, an ideal situation for content distribution. This fact also allows new encoders to emerge over time, using different approaches in compression processes. There are thus encoders that produce better images than others, in addition to being generally parameterized, that is, the compression quality can be adjusted.
