If you are trying to enjoy YouTube videos in MKV format offline on any device, this article may help you a lot. Following we will introduce the MKV format for you and teach you to download YouTube videos as MKV files with a professional third-party tool.
MKV (Matroska Video File) is a new multimedia packaging format. This packaging format can package a variety of different coded videos, 16 or more pieces of audio in different formats, and subtitles in different languages into one Matroska Media file. It is also one of the open-source multimedia packaging formats. Matroska can also provide very good interactive functions at the same time, and it is more convenient and powerful than MPEG.
The biggest feature of Matroska is that it can accommodate a variety of different types of encoded video, audio, and subtitle streams, and even includes streaming media such as RealMedia and QuickTime. It can be said to be a major subversion of traditional media packaging formats! It has almost become a universal media container.
The MKV format supports H.264 AVC, which is necessary for high-quality HD playback, so MKV format has also become the recommended format for HD or Blu-ray playback.
