钢之炼金术师 FULLMETAL ALCHEMIST 是一部非常经典的老番。受限于当年的后期制作技术,素材的有效分辨率仅 540p,因此在糟糕的缩放算法作用下,线条有非常明显的锯齿。我们对线条进行了抗锯齿处理,并且进行了自适应的锐化;对于后期加入的 FHD 的 staff 信息,也使用 Mask 进行了有效的保护。平面部分使用了常规的去色带和自适应降噪。
FULLMETAL ALCHEMIST is an old yet fabulous anime. Limited by the post-processing techniques available in the old days, the native resolution is only 540p. As a result of a poor upscaling algorithm used, the lines are highly aliased, so we applied anti-aliasing and adaptive sharpening to the lines. As for the staff info which has a FHD resolution, we also used Mask to effectively protect the details. Regarding the planes, we applied routine de-banding and self-adaptive de-noising.
