What is MKV to MP4 Conversion and Why Do It?

MKV is especially popular in the home theater and media archiving community because of its flexibility and ability to contain multiple audio and subtitle tracks simultaneously.
What is MP4 Format?
MP4 (MPEG-4 Part 14) is the most widely supported video container format in the world. It is the standard for online video, streaming services, smartphones, and professional video production.
