How to convert HD video to play back on Vega

Hello everyone, this has been related in a couple of additional threads however I can’t look like to find out a assured reply. I’ve got some BluRay rips mostly in .MKV file format that I desire to convert to run back on my Vega (also in HD). Which kind of settings need I utilize to convert them? (I own hd converter as well as GOTSent). As usually, any assistance fine appreciated!!
