A Brief Summary of MKV vs MP4 and Difference between MKV and MP4

In layman's terms, MKV(Matroska) and MP4(MPEG-4) are video formats. To comprehend, better consider them as the container in which video & audio streams are contained. Usually, we have a wide range of video sources and a wide variety of encodings. MKV is currently the most suitable package format – it can help to wrap up anything. Thus, is MKV better than MP4?

- The Major Difference Between MKV and MP4:

MKV was specifically designed to be a universal container, it supports content of any codecs – which makes it an all-purpose container, unlike MP4, which is restricted in specific video/audio encoder. Encoder means much to a video file, it determines its quality, size and device support, and different encoder vary from each other to a large degree, that’s why MKV differs MP4 a lot.
