原盘画质较好,原生分辨率为 810p,但拉升上来之后被裁剪掉了一部分像素,所以实际有效原生分辨率只有 806p。线条有轻微的锯齿和晕轮,部分场景有轻微的色带。我们计算了偏移参数来对画面进行逆向拉伸再重构。然后做了常规的去色带、补偿性锐化和自适应降噪。
The source quality is decent. Its native resolution is 810p, but actually 806p due to the cropping after upscaling. Lines are with slight aliasing and haloing, and some scenes show slight color banding. We calculated the shift parameters to descale and reconstruct the source with moderate de-banding, contra-sharpening and adaptive denoising applied.
