IS: Infinite Stratos / 名作之壁 10-bit 1080p HEVC BDRip [S1-S2 + OVAs Fin]

全系列原盘画质一般，制作非常混乱。原生分辨率为 720p，官方采用了多种劣质拉升算法，导致线条呈现多种画风：第一季时而锐利有严重的锯齿和振铃，时而模糊带有轻微锯齿；第二季则全部较糊，但时而带有大量细碎锯齿，时而带有轻微的粗糙锯齿。两季度暗场都有较严重的色带，其中第二季更严重一些。特典部分的规格更是五花八门，各种奇奇怪怪的交错源，有的拉丝，有的带缟，有的重复，有的正常，更有甚者是以上四种情况的排列组合，还有带缟剪辑缩放的，基本上无解。

处理方面，我们根据实时分析结果自动选择逆向拉伸重构的流程，并调整了逆向拉伸带来的锐化效果，然后附加适当的滤镜清除残留的锯齿和振铃，让各种算法得到的结果相近，以尽量统一画风。最后是常规的自适应去色带、补偿性锐化和自适应降噪。对于特典，我们人工挑选出了带缟的画面，通过拆场逆向拉伸解缟，然后做了时域稳定以改善线条的时域抖动现象，最后使用具有较强抗锯齿效果的倍高滤镜拉升回来，具体可看第 4 组对比图。部分特典出现了带缟锐化的情况，导致缟缟周围有一圈缟状晕轮，这东西实在奇葩，只好硬着头皮拆场去晕轮然后再解缟，具体可看第 1 组对比图。对于带缟缩放导致没法通过逆向拉伸处理的，我们使用了强力 AA 加收线锐化处理，具体可看最后一组对比图。剩下的就是对症下药，进行反交错、IVTC 等操作，就不再赘述了。

部分剧集内封评论音轨。
