MKV is short for Matroska, a container that is able to store videos, audio, and subtitle tracks in multiple codecs. It’s a commonly used video format; you may have seen it before when you were watching movies or TV shows. Or get an MKV file from online downloads. However, not all media programs support MKV format due to the codec incompatible problem. Given that situation, you’ll need to convert MKV files to other video formats for better playing, editing, and sharing.
