本番画质最显著的特点就是画面高度模糊,刚开始看一度让我以为我的播放器设置有问题。对画面经过分析后,我们发现蓝光原生分辨率只有 720p,然后用一种极度低级而模糊的缩放方式放大到 1080p。虽然可以无损还原回去,然而本片 OP 部分,以及 ED 部分字幕是原生 1080p 分辨率。为了保证这些细节不被破坏,我们将原生 720p 部分还原,然后用更通用、更锐利的缩放方法拉升到 1080p,使得整体的画面看上去更统一。
The biggest issue with the image quality is that the scenes are just too blurry. At first sight, I was even thinking if there's something wrong with my media player settings. After some analysis, we determined that the source has a native resolution of only 720p, and was upscaled to 1080p using an awfully primitive and blurry scaling method. We could have simply used lossless de-scaling to restore everything back to 720p, but the OP and some text in the ED are actually native 1080p. To save these details, we de-scaled only the 720p parts, then upscaled to 1080p using a more general and sharper scaling method. This makes the scenes appear much more consistent overall.
