After a long, exhausting day you came home, had your dinner and then sat in front of the TV looking for a nice relaxing movie. You took out your laptop, inserted the first CD and hit “play”. To your surprise, the only thing you could see was a green screen. You took out the CD, cursing at the media market that gave you a “broken” CD for the fifth time. Having yelled at the owner of the shop for five minutes, you suddenly noticed the cynical smile on the guy’s face. Having the opportunity to talk, the shop keeper said “CODEX”. The codecs were the dictionary that your laptop had to use to translate the absurd computer language to the nice scenes of the movies. In the case of big data entries like movies, the computer has to use different algorithms to compress the data so that the size does not exceed the standard limits. Without these “dictionaries” (codecs in the case of video and audio files) the code would seem as meaningless to the player or the viewer as it is to you,some of them decrease the quality of the picture and yet, all of them turn gigabytes of data into fair size that can fit into a CD or a DVD.
some of them decrease the quality of the picture and yet, all of them turn gigabytes of data into fair size that can fit into a CD or a DVD. MPEG4 - It is the default codec which is already included in WMP.
DIVX - A series of sound and display codex which come with shareware DIVX player, AC3 - Most common sound codec.XVID - Relatively new, one of the most used video codecs.Rather useful series of codec which a new version pops out everyday. To many, it would seem that it is getting harder and hard to watch movies. The least you can do is to download a codec viewer program which would help you on your quest for a pleasant evening .
