原盘画质较差,原生分辨率 720p。线条锐度较高,有毛茸茸的锯齿和明显的振铃,还有后期锐化造成的晕轮。平面噪点较多,没什么色带,就是部分噪点压碎后观感欠佳。处理上,逆向拉升重构、抗锯齿、去振铃、去色带、补偿性锐化,再抹去一层动噪,最后再根据亮度进行自适应降噪。
The image quality of the BD source is poor, with a native resolution of 720p. The lines are sharply defined, with hairy aliasing and noticeable ringing. There's also haloing caused by post-sharpening. As for flat areas, the noise is slightly more and there isn't much banding on the whole, but the badly-encoded noise has a really bad viewing. In terms of processing, we applied descaling and reconstruction, anti-aliasing, de-ringing, de-banding, and compensative sharpening, then removed a layer of dynamic noise. Finally, we performed luma-adaptive denoising.
