Description
MKV Matroska is an open-source multimedia container format that supports more than one audio and subtitle tracks in the same file. It is the most convenient file type where you can add a large sum of data, such as videos, audios, texts, and various images. It is a RAW format which you can later flip and separate based on needed data tracks.
Technical details
Whether it is video, audio, subtitle, or image, every file will be stored in a separate data line. It is a lot similar to the MP4 or AVI format, although when users are packaging an MKV file, they rarely bundle all the tracks within the file. Various media players don't even support the MKV video format; therefore, the users need to use specialized media players who can help the MKV format, such as VLC media player.

AAC is highly efficient with variable and continuous bitrate, with a sampling frequency of 8-96 kHz.
