I have some clues for MKV and Premiere Pro issues.
I normally receive my stuff in a format I can stick on Adobe Premiere Pro. MKV's are not compatible. What I want to do with the current project is take the MKV I have and convert it for use with Adobe Premiere Pro. And what I need is a MKV converter I know.
After multiple testing, I found the best and easiest way to import MKV files into Premiere Pro along with the help from a video converter app like MakeMKV or Brorsoft Video Converter.
