What is XviD?
XviD is an open source MPEG-4 video codec designed for everyone. Its purpose is to compress video in order to allow for faster transmission over computer networks or for more efficient storage on computer disks. Hence, XviD can somewhat be seen as a ZIP archive for video. XviD removes information from video that is not important for human perception in order to achieve very high compression rates while still keeping very good visual quality. As an example: uncompressed digital video is huge and takes up about 100 GB HD space per hour at PAL resolution. The same video would require just 500 MB per hour when compressed with XviD at high quality. So XviD can compress video at ratios of 200:1 and more.
Why should I use XviD?
There are a number of reasons for using XviD;
- XviD is free, and can be obtained free of charge and is shipped together with many hardware devices.
- While being free, XviD offers outstanding quality and performance clearly surprising expensive, competing products.
- XviD allows you to create video for interoperable exchange with portable or home multimedia devices as XviD is widely supported in hardware.
- Being open-source, XviD is future-proof and secure to use.
How much does XviD cost?
XviD is Open Source Software and published under the GNU GPL license. That means it can be obtained free of charge. No feature-limited version, no restricted testing period, no nothing.

Many different Linux distributions are available today with rather different features and characteristics. XviD should run on all of them but binary packages are not maintained for all. Actually, it is rather easy to compile the XviD source packages under Linux, therefore just few selected Linux distributions are covered here:
