Part 2. MKV vs M2TS

An MKV file is a video file stored in the Matroska multimedia container format. It supports lots of audio and subtitle tracks. MKV is not as common as MP4 format, but it’s still supported by many media players including Windows media player, VLC media player, and more. It’s often used for storing movies and TV shows.

A file with the .m2ts file extension is a MPEG-2 transport stream file. Videos on Blu-ray discs are saved in M2TS and most HD camcorders record videos in M2TS format.

MKV vs M2TS, which is better? MKV takes less space, while M2TS preserves high-quality resolution in videos and takes much space. What’s more, MKV files are more compatible with media players.
