The DIVX extension identifies video files that use the DivX Media Format (DMF) as a container and contain DivX encoded video.
DivX refers to a highly efficient video compression method that supports MPEG 4 fut and resolutions up to 1920x1080 (FulHD). This process was developed by DivX LLC, which now belongs to Sonic Solutions. It is proprietrous and lossy.
Even though the video stream in DIVX files is encoded using this method, the DMF includes more than this.
Video data encoded with DivX may also be present in other container formats, such as avi or mkv. These container formats support in contrast to DMF but also other compression methods.
The container format DMF, which is identified by the extension DIVX, supports DVD-like functions. For example, a DIVX file may contain menus and navigation, and in addition to multiple audio and video streams, subtitles, chapters, and metadata are also supported.
Many hardware players, such as DVD players, can play DivX encoded material. They do not necessarily support files with the extension DIVX or their special properties. DivX LLC certifies devices with different seals. On the basis of these seals one can recognize which functions are supported. These devices include media center, TV, DVD player, BluRay player and portable devices.
Divx also supports streaming and is therefore increasingly found on the Internet.
While many software players can play DIVX files, many do not support all features.
Most often resolving problems with opening DIVX files is very simple. Just install an appropriate program that supports such files. All of the listed programs support DIVX files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of DIVX files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate DIVX files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the DivX applications is not on the list, select "Browse" option in order to manually locate the directory where DivX has been installed.
Sometimes problems with opening DIVX files may not lie with the application itself, but can arise due to other causes, such as:
