Windows Media Video (WMV) is a common and widely supported video format. It compresses the file size with a codec resulting in an easy-to-manage file that maintains the quality of the video. A digital container format, called Advanced Systems Format (ASF), often encapsulates WMV files.

 

How to open a WMV file?

Most media players can open and read WMV (and ASF) files. The best player for opening a WMV file is Microsoft Windows Media Player. Microsoft developed WMV and ASF, and many videos online today are WMV files. VLC media player is another reliable option, which can play multimedia files across several platforms.

 

WMV is also easy to convert to other video file types. However, keep in mind that the conversion process might cause picture quality to decrease. If a conversion is needed, then HandBrake is a free and open-source tool for converting WMV files.

Matroska (MKV) is a free, open-source, container standard that can hold an unlimited amount of audiovisual and multimedia files in a single file format. Since it is open source, a user can customize it with open-source software. The name derives from “Matryoshka” dolls, which is a famous type of Russian handicraft that consists of a set of wooden dolls of decreasing size nested one inside another.

 

How to open an MKV file?

The best way to open an MKV file is to use VLC media player. This media player is compatible with all operating systems and platforms. This is important because MKV is not an industry standard, which means that other media players might not support it.

 

Additionally, MKV does not use codecs to compress file size, which means the file can be quite large. Therefore, another option for opening an MKV file is to download the appropriate codecs that are compatible with the selected media player. To accomplish this, download the Combined Community Codec Pack (CCCP) from a trusted site, such as Ninite.
