Extended Knowledge: MKV and iMovie Format

MKV(Matroska Video) is a popular format for online video distribution (particularly through BitTorrent networks and all). It is an open and free container format to hold an unlimited number of video, audio, picture, or subtitle tracks within one file.

It offers high quality and is non-proprietary, but due to its complication, it often takes relatively larger size than other video format, even, due to its online origin, some users may doubt on its authority. For users who want to watch some HD movies or videos, MKV is a good choice.
