MKV (Matroska) is a very popular format known for its extensibility. So much so that some experts agree that it could eventually become the standard multimedia format. However, not all devices and media players support this format for now. Oposoft MKV Converter can help you convert MKV videos to a very wide range of formats for playback on those devices that still don't support MKV.

With its very intuitive interface, this software is unlikely to pose any difficulty even to the inexperienced user. The program supports converting various MKV files in a single session. In order to ease the process of converting multiple clips, the application supports adding whole folders. Fortunately, not only Matroska is supported as input but also some other popular formats, such as AVI, FLV, SWF, 3GP, MP4, RM, WMV, MPEG and MOV. If these files contain several audio tracks and embedded subtitles, you can pick the ones you prefer. However, the program does not allow embedding subtitles from external files.

You can preview videos and while watching them you are allowed to take snapshots of your favorite frames. In addition, you can perform some basic authoring actions to use the program as a simple video editor. Thus, the program allows you to extract a segment from a clip and crop a region from a frame. In addition, it lets you combine various files. Finally, you can also apply such effects as flipping and rotating the image, or adjusting the sound volume.

Despite the fact that the program is specifically oriented at MKV conversion, it actually supports a wider range of input formats and an impressive array of output formats. Several conversion profiles are organized according to either their base format or supported devices. By choosing a profile corresponding to the intended gadget, you can avoid compatibility issues. Unfortunately, the program lets you customize these profiles, but it does not allow you to create new ones.

All in all, Oposoft MKV Converter is an excellent application that supports many more formats than just MKV, which makes it a general-purpose converter. However, you might want to test this software to make sure it can convert between all the needed formats. Unfortunately, some sources, like DVD, BD, or Internet video, are not supported.
