Variable bit rate encoding is also commonly used on MPEG-2 video, MPEG-4 Part 2 video ( Xvid, DivX, etc.

Xvid is a primary competitor of the DivX Pro Codec.

In contrast with the DivX codec, which is proprietary software developed by DivX, Inc., Xvid is free software distributed under the terms of the GNU General Public License.

This also means that unlike the DivX codec, which is only available for a limited number of platforms, Xvid can be used on all platforms and operating systems for which the source code can be compiled.

Xvid is not a video format – it is a program ( codec ) for compressing and decompressing to the MPEG-4 ASP format.

Since Xvid uses MPEG-4 Advanced Simple Profile ( ASP ) compression, any video that is encoded with it is termed " MPEG-4 ASP video " – not " Xvid video " – and can therefore be decoded with all MPEG-4 ASP compliant decoders.

All except XvMC are capable of decoding videos encoded with MPEG-1, MPEG-2, MPEG-4 ASP ( MPEG-4 Part 2 ), MPEG-4 AVC ( H. 264 / DivX 6 ), VC-1, WMV3 / WMV9, Xvid / OpenDivX ( DivX 4 ), and DivX 5 codecs, while XvMC is only capable of decoding MPEG-1 and MPEG-2.

ffdshow is a media decoder and encoder mainly used for the fast and high-quality decoding of video in the MPEG-4 ASP ( e. g. encoded with DivX, Xvid, or FFmpeg MPEG-4 ) and AVC ( H. 264 ) formats, but it supports numerous other video and audio formats as well.

HRHD is an unofficial standard of encoding video, meaning that the video signal was ripped directly from a HDTV broadcast, then downsampled to approximately 960 × 540, and usually encoded with Xvid.

It is most commonly used in MPEG-4 ASP, such as with the DivX and Xvid codecs.

The key parts to be aware of are MPEG-4 part 2 ( including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by QuickTime 6 ) and MPEG-4 part 10 ( MPEG-4 AVC / H. 264 or Advanced Video Coding, used by the x264 encoder, by Nero Digital AVC, by QuickTime 7, and by high-definition video media like Blu-ray Disc ).

For example, video created with a standard MPEG-4 Part 2 codec such as Xvid can be decoded ( played back ) using any other standard MPEG-4 Part 2 codec such as FFmpeg MPEG-4 or DivX Pro Codec, because they all use the same video format.

However, Xvid can optionally encode video with advanced MPEG-4 features that most DivX Certified set-top players do not support.

Many video encoders ( such as DivX, Xvid, and 3ivx ) and compression standards ( such as MPEG-2 and H. 264 / AVC ) allow custom matrices to be used.

* MPEG-4 Part 2 ( including video encoded with Xvid, 3ivx, and all versions of DivX ).

In these editors, ffdshow can also be used to encode MPEG-4 video compatible with Xvid, DivX, or x264 codecs, as well as lossless video and a few other formats supported by libavcodec.

Recently, more and more players are enabling compatibility to the DivX video format and its open-source parallel, Xvid.

The most traditional ways of evaluating quality of digital video processing system ( e. g. video codec like DivX, Xvid ) are calculation of the signal-to-noise ratio ( SNR ) and peak signal-to-noise ratio ( PSNR ) between the original video signal and signal passed through this system.

Primarily due to concerns over patents, the official Xvid web site does not provide binary versions of the Xvid codec.

* Xvid: Free / open-source implementation of MPEG-4 ASP, originally based on the OpenDivX project.

Compatible with other standard MPEG-4 codecs like Xvid or DivX Pro Codec.

Several popular codecs including DivX, Xvid and Nero Digital implement this standard.
