Xvid Codec and Xvid Player
XviD is a popular new video codec (a high quality open-source MPEG-4 codec) just like DivX. Most new movies and videos are being encoded with XviD. Despite being open source its extremely good quality, fast encoding speed and efficiency has made it one of the most popular video codecs online. While XviD still isn't as widely used as DivX, playback of XviD movies is usually supported in new DVD players nowadays.
Great News: Without installing Xvid codec, you can rip DVD to XviD directly using DVD Ripper Platinum.
The XviD codec makes it possible to compress a full-length DVD-quality movie enough to fit on a single CD (might require 2 CDs depending on the length of the movie), while still maintaining the original image quality. Despite the fact that XviD movies offer higher quality video at smaller file sizes they take less time to encode than MPEG-2 due to the incredible compression technology. The video is usually combined with MP3 or AC3 audio to enable both high quality video and audio.
The XviD Codec is needed to play movies encoded by XviD. Once you've installed the XviD codec on your system you will be able to play XviD videos using Windows Media Player or any other XviD-enabled player. XviD is the best currently available MPEG-4 video codec solution and additionally XviD is free software!
