向山进发系列作画非常优秀，深受本组多名组员喜爱。可惜蓝光原盘的画质不是很好，制作也颇为混乱。通过分析，可以判断全季度的母带原生分辨率均为 720p，且官方使用了两种不同的低质算法拉伸图像，导致部分镜头可见较为粗糙的微弱锯齿，整体观感较为模糊；部分镜头则可见细密的锯齿，伴有较强的振铃，整体观感非常锐利。

更糟糕的是，这两种算法拉伸的画面在第一季和第三季中混杂在一起，大部分集数中可以看到两种不同“画风"的镜头不断交替出现。此外，第一季和第三季原盘还有明显的色带，在第一季尤为严重。附带的特典部分则在前述问题之上更体现了交错视频的各种常见问题，混合交错、缟缟不一而足。

处理上我们对症下药，首先确定所有正片的每个镜头使用的拉伸算法，进行必要的切割后，分别做对应的逆运算将画面缩小至 720p，再使用高质量算法全部拉伸至 1080p，并附加适当的滤镜清除残留的锯齿和振铃，将全部画面的风格统一。针对第一季和第三季顽固的强色带，我们使用了较为暴力的平滑滤镜来清除。

Yama no Susume series has outstanding sakuga, and is loved by many of our group members. Unfortunately the Blu-ray quality is not very good, and rather messy in terms of production. The whole series appeared to have 720p native resolution, and were upscaled using two different low quality algorithms, such that some of the shots have relatively coarse and weak aliasing, and seem blurry overall; while other shots have fuzzy edges, together with fairly strong ringing, makes the picture very sharp overall.

To make matters worse, these two kinds of visually distinct shots are intermingled in most of the episodes in S1 and S3. Moreover, there are many obvious banded scenes in S1 and S3, especially in S1. On top of all this, the bonus content also has various common issues found in interlaced videos.

We tried to fix these problems accordingly, first analyzed and determined upscaling algorithms for each single shots across all episodes, trimmed as necessary, de-scaled correspondingly back to 720p, and upscaled everything with high quality algorithm, followed up with other AA and de-ringing filters to clean up the residual aliasing and ringing, to make the visual appearance consistent throughout the whole series. We also used strong smoothing kernel to clean up the stubborn banding found in S1 and S3.
