Dungeon ni Deai o Motomeru no wa Machigatte Iru Darouka IV / 在地下城寻求邂逅是否搞错了什么 IV 1080p HEVC BDRip [Fin]

原盘画质较差。原生分辨率非常混乱，大部分素材为原生 900p；少部分素材分辨率较低，比如 800p、810p；还有一部分素材分辨率较高，分布在 900 至 1080 之间，比如 903、946、965、1080 等等。官方制作时的后期处理也是乱七八糟，有时锐化、有时模糊。以上问题导致部分线条有严重的锯齿和振铃。源还加了一层高强度动态噪点，产生了不少压缩瑕疵，少数暗场还有非常严重的色带。

我们进行了逆向拉伸重构，并配合必要的分段和遮罩以处理不同分辨率的素材，辅以常规的抗锯齿和去振铃以清理残留的瑕疵。然后是自适应去色带、补偿性锐化。考虑到体积限制，我们进行了噪点层时域稳定，并配合亮度自适应降噪以控制码率。
