Video Compression Formats


Definition: :

There are several kinds of video and audio compression formats, also known as codecs. Many of them have been standardized by one of two major organizations.

The ISO/IEC, or International Organization for Standardization and the International Electrotechnical Commission, have a group called the Moving Pictures Experts Group or MPEG. MPEG is responsible, for example, for the familiar compression formats MPEG-1, MPEG-2 and MPEG-4.

The ITU-T standardizes formats for the International Telecommunications Union, a United Nations Organization. Some popular ITU-T compression formats include the H.261 and H.264 formats.

There are other compression formats, such as Intel Indeo and RealVideo (based on the ITU-T H.263 codec). These are just as useful as the ones standardized by the international groups, although some video sharing websites won’t accept them.

It’s important not to get video compression formats mixed up with media container formats. A media container is a file format that contains data that had been compressed using a video compression format. So the media container is the end product of video compression.
