The new MPEG4 standard, which appeared at the very end of 1999, offers a broader view of media reality. The MPEG3 standard was originally developed for use in High Definition Television (HDTV) systems with a data rate of 20-40 Mbps. The MPEG-2 format is also the basis for digital television standards. It is this format that underlies DVD-Video discs. Perhaps everyone is familiar with the MPEG-2 format. MPEG-1 is a lossy compression standard for video and audio. There are many versions of the format - MPEG-1, MPEG-2, MPEG-3, MPEG-4, etc.
This technology defines the compression standards for both audio and video information and makes it convenient for transmission in broadcast. MPEG compression standards were developed by Moving Picture Experts Group.

In January 1988, an expert working group on coding of moving images was formed within the framework of the joint information technology technical committee JTC1 of the International Organization for Standardization ISO and the International Electrotechnical Commission IEC, which was tasked with developing standards for image and sound coding with the aim of eliminating redundancy. Below you can find out some details about the original and new file formats. In any case, with the help of our converter, you can easily complete the required task. Perhaps you just need to extract the audio track from the video file, in which case converting the video to audio format is a good option. Also, conversion is often required to reduce the file size, since the original format takes up too much space in the device's memory. So, for example, you may want to convert MPEG to MP3 if your computer, phone or other device does not support MPEG format.

The difference is massive and so are the download times.Converting one file format to another may be necessary for various reasons. RAW file formats generally require 176,000 bytes per second compared to a lossy format which requires 17,600. By using lossy formats it enables even dial up users to download mp3 files at a reasonable speed. The reason lossy formats are used over RAW is that RAW audio files are too large to travel over the internet at any great speed. In other words, that means it removes the information that your ear doesn't notice thereby making the file smaller. Instead, MP3 files use perceptual coding. That means that an MP3 file does not contain 100% of the original audio information. This then enables you to get hundreds of songs on to a CD and it also has opened up a new market over the internet - the download market as download times have been significantly reduced.
MP3 gets rid of a lot of the information recorded in a song that our ears are not able to hear and then uses complex algorithms to reduce the file size. MP3 is a digital music format which allows CD tracks to be reduced to around a tenth of their normal size without a significant loss of quality.

Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. MPEG-4 Part 14 or MP4, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4.

Since stores like iTunes uses this container format, and it is used with iPod and PlayStation Portable (PSP), MP4 files have become more common. MP4 is a container format that can store video, audio and subtitle data (as well as more depending on content). MP4 files (MPEG-4 Part 14) are multimedia files.
