原盘画质一般,原生分辨率为 837.3p。主要问题是制作时使用了力度较大的锐化,线条有比较严重的锯齿和振铃。我们的处理手段是逆向拉伸重构,并配合必要的分段和遮罩以保护原生 1080p 的素材,接着进一步处理了残留的锯齿和振铃。原盘只有少量暗场有轻微的色带,我们使用了自适应去色带以自动调整去色带力度。最后是常规的补偿性锐化和自适应降噪。
JPBD 最后一卷的两集出现了非常严重的色带和色块,可参考最后 3 组对比图。这色带实在是过于恐怖了,无奈之下我们翻了一下 CrunchyRoll 的 web 源,发现部分场景 CR 比 BD 要好得多,所以我们将这部分替换为 CR 源进行制作,并针对这两集加大了去色带力度。
The original source is of average quality. It has a native resolution of 837.3p. The main problem is that the studio applied excessive sharpening during production, resulting in noticeable aliasing and ringing in the lines. We applied descaling and reconstruction, combined with the necessary scene-filtering and masking to protect the native 1080p materials, and then further dealt with the remaining aliasing and ringing. There's only a small amount of dark areas of the source showing mild banding, so we used adaptive de-banding to automatically adjust the strength of de-banding. Lastly, we applied conventional compensatory sharpening and adaptive denoising.
The two episodes in the last volume of the JPBD show very severe colour banding and blocking. This can be seen in the last three sets of comparisons. The banding was extremely bad, so we checked the web source in CrunchyRoll and found that some scenes there were much better than in the BD. We therefore replaced these parts with the CR source for production and increased the de-banding strength for these two episodes.
