青春之旅 / Ao Haru Ride / アオハライド TV BDRip + OAD DVDRip
原盘画质较好，原生分辨率大约为 864p。唯一的问题就是线条上有锯齿，对此的处理方案是逆向拉伸重构接轻度抗锯齿。平面整体不错，几乎没有色带，噪点层也非常理想，所以对平面的处理是自适应纹理锐化，保底的去色带，以及保守的自适应降噪，同时为了保留画风，保留了色度噪点。为了更大程度地保留作品中的画风细节，编码参数上给了色度平面相当奢侈的预算。
OAD 的画质较差，线条很虚且粗细不均，周围有非常显眼的振铃。平面上噪点质量也比较差。对 OAD 的处理包括 IVTC，色彩空间转换，多轮的去振铃，使用神经网络算法的拉伸，降噪，重构噪点层，去色带。
因为 OAD 源的截图与成品分辨率不一致，为方便比较，这部分的截图是在做了 IVTC 以及色彩空间转换后以 Spline36 拉伸到了和成品相同的分辨率。
The BD source for the main TV series is decent, with a native resolution of around 864p. The only issue lies in line aliasing, for which the solution is to apply descaling and reconstruction followed by slilght anti-aliasing. The flat areas are fine, exhibiting almost no banding, and the noise layer is also very ideal. Therefore, treatment for the flat areas involved adaptive texture sharpening, a minimum amount of de-banding, and quite conservative adaptive de-noising. Meanwhile, to preserve the art style, we kept the chroma noise. High bitrate was also generously allocated to the chroma plane with an intent to retain the drawing and art style related details.
The OADs, on the other hand, have a much worse image quality. Lines look faint with inconsistent thickness, and ringing is very obvious. The noise layer is poor looking, too. PP for the OADs involves IVTC, colour space transform, multiple rounds of de-ringing, scaling with a neural network based algorithm, de-noising, reconstruction of the noise layer, and de-banding.
As the screenshots from the OAD source have a different resolution than the output, for ease of comparison, the screenshots underwent IVTC, colour space transform, then scaled with Spline36 algorithm.
