The abundance of video formats, which number about fifty, puts any user before a choice which format to use. And in this matter it cannot be said that some option is better than others, because different video formats are used for different purposes.
However, consideration of the concept of video format is impossible without consideration of the concept of codecs. A codec is a kind of microprogram that converts information in order to save and reproduce it easier. However, the basic structure of the file (it is also called a container) is practically unchanged, and therefore it is the same for all files. The most popular codecs in recent years are DivX, MPEG2, XviD, and H.264. The future video format depends on the use of a specific codec.

DivX is the most popular codec. Gained widespread use in the era of video cassettes. However, with the fifth version, a license to use it became paid. Unlike the previous two, the main application of the MPEG2 codec is digital television. The reason for this is the high speed of processing information of this kind. In addition, it is often used when recording video discs and when compressing video files.So, we examined the most popular video codecs, and now we will go directly to the video formats. The most used, which in principle and logical, are the simplest, namely AVI, MP4, MKV and TS.
AVI is the most widely used video format. The scope of its application is almost limitless. It is the basis of some other formats. The decoding of his abbreviation literally translates as the alternation of audio and video. Its main advantage is the ability to combine several video streams, as well as the addition of other streams, up to text information. When creating this video format, many different codecs are used, which explains its versatility.MKV Matroska Video – , , . , , , . , . .
However, video formats are not an integral structure; they can be changed. Now changing the video format is, roughly speaking, a trifling matter. Even a beginner can cope with it. Since literally every user has a program loaded on the computer to change the video format. And most often, these are programs for changing the format of not only video, but many files, so they become popular.
