Matroska Video File
| Extension | .mkv |
| Category | 🔵 video |
| Programs | 🔵 VLC Media Player |
| Main program | 🔵 VLC Media Player |
| Description | 🔵 Matroska, more commonly known as MKV, is an open-source multimedia container format. It's designed to hold multiple audio and subtitle tracks within a single file. This format is highly adaptable, supporting a wide range of data types, including videos, audio, text, and images. Matroska functions as a RAW format, meaning it's a fundamental, uncompressed format that allows for easy manipulation and selection of specific data tracks. Whether the data is video, audio, subtitles, or images, each is stored as a separate data stream. |
| Technical details | 🔵 This format shares similarities with MP4 or AVI formats. However, when creating an MKV file, users typically don't combine all tracks into one container. Importantly, many standard media players don't support the MKV video format. This is partly due to the format's complexity and the wide variety of codecs it can use, which many players aren't equipped to handle. Consequently, users need specialized media players to handle MKV files. VLC media player is one example, along with PotPlayer and KMPlayer. |
