原盘画质不错,可能官方做了锐化,画面整体锐度偏高。线条很粗,有轻度锯齿和振铃。平面色带不明显,噪点强度适中质量尚可。无论是去色带、抗锯齿、去振铃还是补偿性锐化,我们均采取了较轻的强度,最后是自适应降噪。
The source looks great. It also looks sharp, which might be due to the sharpening process by the official. The lines are thick with slight aliasing and ringing; the flat area looks decent, with no apparent banding and moderate noise. So, all processes we applied (de-banding, anti-aliasing, de-ringing, and compensatory sharpening) are lighter. In the end, we used adaptive denoising.
