About the MKV Format
MKV (Matroska Video) is an open-source multimedia container format created in 2002 by the Matroska project. Named after the Russian matryoshka nesting dolls, MKV is designed to hold virtually unlimited numbers of video, audio, and subtitle tracks within a single file. It can encapsulate almost any video and audio codec, making it one of the most flexible container formats available today.
MKV is the preferred format for high-quality video archiving, HD and 4K content, and media libraries that require multiple audio languages or subtitle options. Its open-source nature and codec-agnostic design mean it can adapt to new compression technologies without format changes. The main drawback is compatibility — MKV is not natively supported by all devices, particularly older smart TVs, gaming consoles, and some mobile players. For broad distribution MP4 remains more universally playable, but for personal libraries and archival purposes MKV is often the superior choice.
