Xvid Codec Pack is a free video codec that's strong in compression and quality.Xvid runs very fast as it is optimized for the latest CPUs. Recording video from a camera in real-time or playing back HD video smoothly are not a problem. Your computer will still have plenty of power left for your other tasks!A significant advantage of Xvid compressed video files is that they play almost anywhere. The Xvid software runs on many platforms, and most popular video players support it. Also, home entertainment devices like TVs or DVD/BD players can handle Xvid video.The Xvid codec compresses video files to make them smaller. It can compress video at a ratio of 200:1 or more compared to uncompressed video. This makes transmitting the video over a network faster and saves you a lot of space on your computer's hard disk.While Xvid compresses video very well, it can do so without causing visible quality loss and by retaining a sharper picture than other codecs do. Xvid is "lossy" compression but aims at removing just those picture details that are not necessary for human perception. As such, it is seen as an MP3 for video.
