No matter how much bitrate is thrown at this cropped 4K footage, there is no way of getting around banding while staying in an 8-bit space. The same render in 10-bit shows no sign of banding at all, even when compressed down to 10Mb/s HEVC 2160p24. Is this banding apparent while watching on a 6.5” iPhone XS Max screen? no not really. But on a 65” OLED in HDR sitting 8’ away the banding is easily apparent.
