The video codec is a supplementary invention that has developed around compact discs. The presence of the CD made it necessary to store knowledge onto it in a digital format. The development of Web, the development of transmitting multimedia files over the Web, provided the pace for the development of video codecs.xvid

In any digital video file, there is a lot of knowledge that can be compressed. This can be redundant knowledge such as a string of knowledge that contains of zero bits. Now, in lieu of representing all zero bits, a single integer can be used to indicate all of them. This is an example of how redundant knowledge is bunched together to compress the general file. This reduces the size of the file making it simpler for transmission and storage.

The decompression works in exactly the opposite way. codec pack The individual binary digits are reassigned so that the video can be played back as much in its original form as feasible.windows codec

Video codecs work by compressing the video for the size of the knowledge contained in it as well as the amount of bandwidth that is necessary to transmit it. Different applications will have different ways of compressing knowledge, but these are the general ways in which this is completed. Both kinds of compression are needed when using video files over the Web.watch free movies

Using video codecs is definitely essential in today's age, but the use is not without its compromises.codec download of the main compromises is on the quality of the knowledge that is produced through the compression and later decompression. When the knowledge is compressed and then decompressed, there is always a possibility of loss and distortion of knowledge. This cannot be avoided because compression is mostly an unpredictable process. It is difficult to say how the file will be compressed each file has a different way of being compressed and each codec will use different principles . That is the reason the finish result cannot be predicted. In fact, professionals shun video codecs because of this reason.
