原盘画质一般,原生分辨率为 720p,线条有明显的低分辨率劣质拉伸带来的锯齿和模糊,此外部分背景线条还有额外锯齿,少数场景有轻微色带。我们使用逆向拉伸重构,配合进一步的抗锯齿和去晕轮处理来优化线条。最后进行轻微的去色带和自适应降噪处理,并针对动态噪点进行削弱来控制码率。由于本片作画强度高,动态场景丰富,给的码率较为充足。
The image quality of the source is about average, featuring a native resolution of 720p. The lines display aliasing and bluriness, typical result of a low native resolution and a poor upscaling algorithm used. Aliasing was also observed in the background lines, too. In addition, a few scenes suffer from mild colour banding. We applied descaling and reconstruction, accompanied by anti-aliasing and de-ringing to improve the lines. PP was finalized by using slight de-banding and adaptive de-noising, which reduced a certain amount of dynamic noice to control the bitrate. Speaking of the bitrate, because there are a lot of drawing details and dynamic scenes, a high bitrate was selected for encoding the files.
