And even then I've found that it still requires tweaking. With x264, pick a preset, crank the RF high enough, and it'll come out transparent. I haven't seen any of my own x265 encodes, even for high RF encodes (RF16+), come out transparent without adding '--no-sao --aq-mode 3' (without aq-mode 3 - dark areas are prone to blocking (especially SD sources), without no-sao - film grain is easily lost).
