原盘画质偏差,原生分辨率 898.9p。主要问题是原盘码率不足造成的欠码。不知道发行商在灌录时处于什么样的精神状态,一张 BD50 里塞了 8 集(JPBD 一般最多也就 6 集),导致标称码率差不多只有常规的 75%。好在正片除了欠码造成的蚊噪、色块、烂噪外,没什么其他太重的瑕疵,就是一些线条锯齿。反倒是 OP、ED 的情况不容乐观,OP 有大量的特效和严重的振铃,ED 则覆盖了过多的艺术性噪点,再经过欠码摧残之后有别样的“韵味"。处理上,正片采取了自适应去色块、逆向拉升重构、去色带、抗锯齿、补偿性锐化、自适应噪点层重构;OP 和正片类似,不过由于特效和振铃过多没有进行逆向拉升重构,并且直接抹去了烂噪;ED 由于较强的艺术性,在使用了基于神经网络的自适应降噪后,仅进行了轻度的抗锯齿。
The source disc quality isn't great, with a native resolution of 898.9p. The main problem is insufficient bitrate. We will never know what mental state the publisher was in when they crammed 8 episodes onto a BD50 (usually JPBD maxes out at 6 episodes), resulting in a bitrate that's only about 75% of the standard. Fortunately, besides DCT noise, blocking, and grain blocking from insufficient bitrate, the main content doesn't have any major artifacts, just some line aliasing. But the OP and ED are a different story. The OP has tons of special effects and severe ringing, while the ED is full of excessive artistic noise, and after being wrecked by insufficient bitrate, it has its own "charm." For pre-processing, on the main content we used adaptive de-blocking, descaling and reconstruction, de-banding, anti-aliasing, compensatory sharpening, and adaptive noise layer reconstruction. The OP was handled similarly to the main content, but because of the excessive special effects and ringing, descaling and reconstruction wasn't applied, and DCT noise was removed. For the ED, due to its strong artistic style, after using neural-network-based adaptive denoising, only mild anti-aliasing was done.
