原盘画质较好,原生分辨率为 810p,采用较为柔和的算法拉升上来,线条带有拉升产生的锯齿和晕轮,部分场景有轻微的色带。我们在保护原生 1080p 部分的同时对画面进行逆向拉伸再重构,然后是常规的去色带、补偿性锐化和自适应降噪。和本篇一样,大贤者出现的场景有非常高强度的噪点,但我们对峰值码率进行了更严格的限制,以把码率分配到更有用的地方。
The source is of good quality, with a native resolution of 810p. A blurring interpolation algorithm was used during upscaling, and there is some haloing and aliasing around the lines caused by upscaling. Also, a few scenes come with slight banding. Our solution is to descale and reconstruct the images while reserving the parts which are natively 1080p, followed by the usual de-banding, contra-sharpening and adaptive de-noising. Just as in Tensura, the scenes where the Great Sage appears have significant noise, but we put a strict limit on the peak bitrate and then allocate the bitrate to more useful places.
