So I have been experimenting to try and find why my converted Elgato videos look like garbage on my iMac. 2018 27" 3.8 GHZ. So I went ahead and converted the same footage on my PC and it looks totally different and better. No grain or blurriness. So why do converted videos on my iMac look like crap compared to my 4 year old PC laptop? All Elgato settings being equal on both. When I play the PC mp4 on the Mac it looks great too. But when converted on the Mac, garbage. I really don't want to use my laptop to convert these. Thanks.
