Though MKV is a very popular video format and many people use it, few people know that it is short for "Matroska Video". Matroska is a kind of hollow wooden Russian doll which opens to exposes to another doll and you can do it again and again until it is the last doll inside. Just as the name implies, MKV is also a container of video, audio, subtitle, and picture. It is free and it has great compatibility with Windows, Mac, Palm, Symbian, and even Pocket PC mobile devices.

Recorded videos are mostly in MKV and when you are trying to splice MKV video, an MKV cutter is required. The better option is that you can convert MKV to MP4 or other formats after you cut it. TunesKit Video Cutter is exactly the better option. It is an MKV video cutter, splitter, editor and converter.
