full backstory is available here if anyone is interested, and how I end up on forum of the handbrake

current situation: I have 27 files that I need to convert so they would become error free and not crash premiere pro. Handbrake worked like a charm! Now I need to convert them in a way so I would not loose any quality.
https://we.tl/t-CqsrNsKu9K for example. I have tried converting video of:
Original file - 95.6 mb.
presets:
apple 4k (it leaves the video 2.7k) - 12.6mb
Vimeo 4k - 23.9
If done manual:
2704x1520, fps same as source (59.94), quality RF 22, encoder options preset: slow, variable framerate - 20.9mb.
so I guess I am loosing (or not) some video data here. What would be the best settings for lossless quality ? 27 of those files varies from 88mb to 1.2gb, so I guess I do not need any compression until prod.
