MKVToolnix is a powerful and versatile toolkit designed to work with Matroska container format – mostly known for extensions.mkv for video and.mka for audio. Although the main application is command-line based, the Windows version offers a convenient graphical user interface called MKVmerge GUI which makes working with it accessible to a wider range of users.
Matroska is an open standard for a multimedia container format. Its popularity comes from its ability to store multiple video, audio, and subtitle streams in a single file, along with metadata, chapters, and even fonts. This makes it extremely flexible and the preferred format for high-quality multimedia content.
