原盘画质很差。原生分辨率是骨头社祖传的 720p。主要瑕疵就是欠码，极度欠码。线条周围有明显蚊噪，平面有极宽极重的色带。线条还很糊，伴有较重的锯齿和轻微的振铃，噪点则聊胜于无，由于色带太重，噪点层中甚至都有残留的色带。我们参考了美版 BD，色带情况略好一些，但有较重的振铃问题（推测是美版在灌录前进行了没必要的拉升），同样不好处理，所以最后我们还是使用日版 BD 进行了制作。如此严重的色带问题，无非就是大力去色带或者直接加噪点掩盖，出于码率控制考量，我们选择了前者。在算法选择上，我们使用了针对巨大色带的新式算法，尽量减少了纹理损失。至于其他欠码问题则采用了基于神经网络算法的自适应去色块处理。由于线条质量也欠佳，我们在逆向拉升重构时选用了更费算力但相对优质的还原拉升算法。其他就是常规处理了：抗锯齿、补偿性锐化、自适应降噪。
