Xvid overview of what it is and what it does.
Xvidis an open source program used to compress and decompress digital video files. Xvid is similar to the DivX software, except Xvid is totally free. Xvid still trails behind DivX in popularity, but numerous new DVD players support Xvid-encoded video formats. Xvid is also cross platform, and can be used on all operating systems.
Codec comes from two words: enCOder/DECoder. Codecs are instructions for packing and extracting digital video. The Xvid codec essentially tells your system how to read digital video. An error message about a missing codec can occasionally pop up when you try to play a video. The video file can be played only when you have the correct codec installed in your system.
Codecstransform digital video into frequencies and signals using mathematical formulas referred to as algorithms. Xvid itself is not a file format like .avi or .mp4. Xvid’s file format is called MPEG-4 ASP (Motion Picture Experts Group-4 Advanced Simple Profile), playable on devices that support this file type.
