iFunia MKV Converter is a commercial video converter. It can be used to convert your MKV files into other formats, including AVI, MOV, FLV, DivX, XviD, H.264, MPEG-4 and others.
The app has a nice graphical user interface. There is a video player that lets you see your videos before conversion and a pane where you can change all the conversion settings. There are a few conversion profiles. Some of the included devices are Xbox 360, Playstation 3, PSP, iPad, iPhone, and AppleTV, among others.
In my testing, I used an MKV file. I trimmed it using the built-in video editor to a 1-minute long clip. Then I selected the subtitle track that I wanted to use and chose H.264 as the output format. The file was converted in less than a minute, which is good. The subtitle wasn't hard-coded onto the video, but the file looked great.
Pros
- It works well
- Nice number of conversion profiles
Cons
- The editor hangs while editing some files
- Subtitles don't work
