Video Format Comparison

DivX vs Xvid — Legacy Video Codec Comparison

DivX and Xvid are both implementations of the MPEG-4 Part 2 (ASP) video codec that dominated internet video distribution from roughly 2000 to 2010. DivX was the commercial codec — originally derived from Microsoft's MPEG-4 implementation. Xvid (DivX spelled backwards) was the open-source response, similar quality, free, and not encumbered by DivX's software protection. Both codecs produce video stored in AVI containers and are now largely obsolete, replaced by H.264 and H.265.

DivXvsXvid

Quick Verdict

Use DivX when…

DivX still has slightly more hardware player support in some older DVD/media players that specifically advertise 'DivX Certified' playback. If you have an old media player that requires DivX, use DivX.

Use Xvid when…

Xvid is the better choice between the two — it's free, open-source, produces equivalent or better quality than DivX, and is supported by FFmpeg and VLC. If you must encode to MPEG-4 ASP (avoid if possible), use Xvid.

Frequently asked questions

Should I convert DivX/Xvid files to H.264?

Yes — H.264 (in MKV or MP4 container) is universally supported by modern devices and achieves much better quality at the same file size. Use HandBrake (free) to convert: open the AVI file, select the H.264 preset, set container to MKV or MP4, and encode. You may be able to shrink files 30–50% while maintaining the same visual quality.

Why were DivX and Xvid so popular in the early 2000s?

In the early 2000s, a full DVD movie encoded with DivX or Xvid fit onto a single 700 MB CD-R and played on any PC with the codec installed. This was revolutionary — DVD ripping became common. The codec's compression efficiency far exceeded Windows Media Video or Real Video at the time. Broadband internet also made downloading 700 MB files practical for the first time.

Can VLC play DivX and Xvid files?

Yes — VLC Media Player includes DivX and Xvid decoders and plays AVI files encoded with either codec on Windows, macOS, Linux, Android, and iOS. No additional codec installation is required. VLC's built-in MPEG-4 decoder handles both formats.
