MKV, or Matroska Video, is a popular multimedia container format that can hold various types of data, including video, audio, subtitles, and images. It is widely used for storing high-definition video content and supports multiple audio tracks and subtitle options, making it versatile for different viewing preferences. One of the key advantages of MKV is its ability to maintain high-quality video and audio while compressing file sizes. This format is compatible with many media players and devices, allowing users to enjoy their favorite movies and shows without worrying about compatibility issues.
