So, i watched it in full. Other than my two notes, i’ve to say it works really well.

33:15, odd change of scenery from exegol to the force talk of rey and kylo. But that’s me, i think it is possible to get used to it
luke destroying the supremacy is a really nice idea, but i not sure it works narrative wise because in the last battle on exegol we never see her (of course we know she still exists in your edit up to this point) and suddenly luke is attacking her through the force. My thoughts though

Regarding your question with encode settings: i think most of the bigger editors use always „crf“ of 18 to 20 and two pass (if there want to achieve a non-noticable compression regarding picture quality) rather than vbr.
