When to Use .MKV

Use MKV for archiving video with multiple audio and subtitle tracks, Blu-ray remuxing, and any scenario requiring maximum flexibility.

Technical Details

MKV uses the EBML (Extensible Binary Meta Language) format — a binary XML-like structure. Each track (video, audio, subtitles) is multiplexed into clusters with precise timestamps for frame-accurate seeking.

History

Steve Lhomme created Matroska in 2002 as an open-source alternative to proprietary containers. The name comes from Russian matryoshka dolls, symbolizing the nested container structure.
