To Love S2 对比 S1 画质可以说是质的飞跃,不仅是画面分辨率连画风也好上不少,不过预处理依然复杂,主要问题在于 Chapter 之间转场的静态画面锯齿较多并带有少许 ringing,与正片较为 soft 的画面形成对比,处理上只能分开处理。 先说下正片,画面盖着较为厚的噪点,好在没有 banding,线条也有少许锯齿,处理上也是简单的根据亮度进行降噪以及 AA。 针对静态画面,预处理试了不少种 AA + dering 方法,效果都不是很好,只能反向拉伸后用较为优秀的算法拉回 1080p,同理 ED 也是这样处理,考虑到 ED STAFF 是 FHD 的,处理上不好直接反向拉伸,并且 ED 里拉伸画面有大量高亮场景,STAFF mask 不好根据 STAFF 亮度进行设计,只能手画 mask 进行遮罩(幸好 STAFF 在的位置不是拉伸画面里,不然我要成人体描边大师了),成品效果还算令人满意。 The Second Season of To Love Ru has a significantly better image quality than Season 1 in terms of resolution and picture style. Lots of aliasing and a trace of ringing can be found in the static images between chapters whereas main videos have a relatively soft picture style. PP for the main videos included anti-aliasing and de-noising. For the static images, we managed to use reverse-scaling and then to bring them back to 1080p with good algorithm, because many anti-aliasing and de-ringing methods did not work well. The same process was also applied on ED with additional masking around ED STAFF areas, the results were about satisfactory.
制作方案上用最新的预处理设计和编码器参数的测试结果,达成了比之前 AVC 版本小,画质比 AVC 版好的效果。 We switched to HEVC for S3-S4 (and revised the previous S2 release) with new PP design and results from our comprehensive test of x265 2.0. Compared with the old AVC version, we achieved better quality with even smaller file size.
