Part 3. General Knowledge About WMV and MKV

In this part, we’ll have an insightful look at both MKV and WMV files. That said, Matroska Video File (MKV) is a video file container format developed by Steve Lhomme and comes with a .mkv extension. It holds videos, images, audios, and subtitles in one file. Because MKV is a RAW format, flipping and turning separate data tracks is easy. MKV plays on many media players, e.g. VLC, 5KPlayer, 4KPlayer, etc.

Windows Media Videos (WMV), on the other hand, is also a video file format developed by Microsoft. It typically features a .wmv extension and a video/x-ms-WMV MIME type. Although many Windows media players support WMV, you’ll need to convert it to another format like MP4, MOV, or MKV to enjoy it on Mac. Even worse, some WMV clips have DRM encryption. Some supported video players include PowerDVD, VLC, MPlayer, and many others.

To sum it up, both MKV and WMV are popular video formats that you’re likely to come across. However, if you’re a Mac OS user, WMV files can be troublesome. So be safe, convert WMV to MKV which is a universal format.
