What is MKV?

MKV (Matroska Video) is a file format commonly designed to store video, audio and subtitle data in a single file. It is an open-source container format that is quite flexible and efficient, allowing for high-quality video and audio playback. An MKV file is similar to other container formats like AVI and MP4 but offers several advantages. For example, an MKV file can support multiple video and audio tracks, different subtitle tracks and chapter markers. It can also support advanced features like variable frame rates and lossless codecs. Hence, an MKV file is often used for high-quality video content, such as movies and TV shows.

What is AVI?

AVI stands for Audio Video Interleave, a multimedia container format developed by Microsoft in the early 1990s. It is a commonly used format known for its ability to support multiple audio and video streams, which allows for the creation of movies with multiple audio tracks and subtitles. Although AVI can be played by many media players and video editing software, it is an older format and has limitations in terms of file size and compatibility with newer devices.
