How to Convert MKV to MP4 while Supporting Quality

Videos from various sources can be formatted in multiple ways, which is one of the primary causes of video incompatibility. Matroska video is commonly referred to as MKV, and it is a format that frequently encounters the circumstances above.

Continue reading this article to understand better why MKV has poor performance over compatibility and what the best solution is.

What is MKV, and why does it have incompatibility issues?

The first distinction that should be made is between video format and video codec, which frequently confounds many of us. A format is similar to a container that holds a collection of streams such as audio, video, and subtitles, among other things. Instead, codec refers to the way by which these streams are compressed.

The extensions in the MKV file folder are MKV for video, MKA for audio, and MKS for the subtitle, and the corresponding codecs can differ. The MKV format “wraps up” various parts of such video, and the codecs that do compression work vary. MKV is a free and open file format. As a way, incompatibility errors are frequently encountered during MKV video playback. For example, if your media player or operating system cannot handle all of the codecs in your MKV file, it may not be able to be played or even supported.

Now that you know the fundamental differences between MKV video format and codec, what should we do to resolve MKV video problems permanently? The key is to overcome its incompatibility with operating systems and media players. We must convert MKV to a more compatible format, such as MP4.
