原盘画质一般。虽然是每集 2 分钟的泡面,但其原生分辨率却是变幻无常。ED 部分和前两集正片的原生分辨率为 720p。后面几集正片原生分辨率为 837p,但一部分是从更高的尺寸裁剪掉四周烂边得来,甚至还有一部分是经过一次拉升到 958.5p,再二次拉升到 1080p 得到的。采用的算法也比较劣质,导致拉升后的画面又糊又有锯齿。我们设计了一个自动化方法,根据实时分析结果自动选择逆向拉伸重构的流程。然后是轻微的去色带,补偿性锐化和自适应降噪。
由于评论音轨的存在,我们选择将 1-12 集合并,以适配评论音轨。
The original picture quality is average. Although it is a 2-minute miniseries per episode, its native resolution is fickle. The native resolution of the ED and the first two episodes is 720p. Later episodes are 837p, but some of them are cropped from a higher resolution to get rid of the dirty edges caused by upscaling. What's more, some cuts even have an intermediate resolution of 958.5p, ending with 1080p by a secondary upscaling. The upscaling algorithm is also poor, which results in blurry images and aliasing. We designed an automated method to select the descaling and reconstruction process based on the real-time analysis results. Then came the slight de-banding, compensatory sharpening and adaptive denoising.
Because the commentary track was recorded uninterrupted from episodes 1 to 12, we accordingly merged all the 12 episodes to fit the commentary.
