Is it the best for quality prob not if you were to scrutinise a side by side but even on a 75" 4k oled I have yet to see any artifacts or degregration and it’s currently saved me having to buy another hard-drive for the moment. The settings are a solid broad stroke super easy to setup qsv. The only failures I have are where it’s already in the format. Well worth adding to your unraid esp if you have older backups.
