南家三姐妹的画质一言难尽,即使在当年的动画中也不算好。第一季线条发虚,且有大量锯齿、断线,以及线条交叉处的奇怪斑点;第二季的线条也有类似的问题,还有明显的色带;第三季的线条也是一样,而且锯齿、断线和晕轮等问题更多,且画面有很重的噪点;第四季画质较好,仅有一点锯齿和色带。前三季度在处理中对线条进行了修复和适度的加深,处理了色带等问题,对第三季进行了适度的降噪以控制体积;第四季做了常规的抗锯齿和去色带处理。对比图每季度四组。
The image quality of the source is a long story. It's not good even in its days. The lines in Season 1 are blurry, with lots of aliasing and dashed characteristic. Besides, the intersection of lines features strange dot-crawl. Season 2 has similar artifacts except for obvious banding. As for Season 3, the lines artifacts remain the same and more serious. The image covers heavy noise as well. Season 4 comes with better image quality, with only slight aliasing and banding. In the first three Seasons, the lines were repaired and moderately darkened, and artifacts like banding were dealt with. Denoising was applied to Season 3 to control bitrate. We adopted anti-aliasing and de-banding for Season 4 as a matter of routine. Four sets of screenshots per season.
总监: 众所周知,南家只有第一季和第四季。
整理: 用了好一段时间,也终归是完成了。
