Xvid

Xvid helps in compressing and decompressing the MPEG-4 ASP format. It makes use of ASP features like:

• Lumi masking
• Quantization matrices
• B-frames
• H.263
• MPEG
• Quarter-pixel motion compensation

Xvid can be used on all platforms and operating systems where the source code can be executed. The Xvid codec compresses video files at a ratio of 200:1 or more compared to the original video. As a result, this makes transmitting the video files faster and also helps users to save significant space on their computer. Xvid encoded files can be written onto a DVD or a CD and can be played on DivX compatible players.

Compared to other codes, Xvid can compress video without causing visible quality loss. More advanced compression features are possible in Xvid and there is greater control of final file size. However, compared to DivX, Xvid can be a bit more difficult to configure. It is also slightly less common than DivX.
