For this example I use Kingsman: Secret Service Full HD Bluray.
But even at RF16 the quality is still noticeable worse, not as sharp and not as many details.
Tbf: You only really see it if you compare frame by frame but the feeling sticks in my head and I just want to delete the remux. I know myself and if the quality is not as good (in a reasonable range) as the remux, I will watch the remux nonetheless and the whole encoding procedure to save space is useless.
Relevant settings are the following:
Filters: Everything is "Off"
- Coded: H.265 10-bit (x265)
- Quality: Constant Quality: 16 RF
- Preset: Slow
- Tune: None
- Profile and Level: Auto
- Advanced Options: None
I added a visual comparison between the Bluray-Remux and the Encode, aswell as the used settings, at the end.
In my opinion it is most visible in the light cast of the window in the top right and the damaged wall on the left.
I mean, perhaps I'm too sensitive (most probably) but maybe there's a way for me to improve it.
