原盘的制作质量相当不错 暗场多 以CG绘制的纹理细节丰富 噪点重而细腻 构成了本片独特的画风 ED更是以全24fps绘制
本作最大问题在于锐利的线条普遍带有很强的锯齿 尤其影响到颜色线条部分 (如琉紫和昂克儿的能力发动型态)
为维持颜色线条的精确度 我们先拉伸UV平面 再通过混合使用传统与非常规方法 在YUV444下修复锯齿
我们也针对噪点进行处理 在控制成品体积的前提下尽可能地维持了其画风和质感
The original source has fair quality, with sharp pictures and many textural details. We can see Xebec spent effort in creating the CG drawings, dark scenes and a 24fps ED. Unfortunately, the sharp edges have significant aliasing in both luma and chroma planes, making non-destructive anti-aliasing challenging. The strong and fine film grain has also made it difficult for x265 to encode the anime at an acceptable bitrate.
To tackle the problems, we adopted a hybrid anti-aliasing approach combining traditional and non-conventional techniques, and operated under the YUV444 color space. The approach repaired most aliasing and without damaging the sharp colored edges. Meanwhile, a tailored grain processing procedure was formulated, which achieved a good balance between picture preservation and bitrate saving.

作为Xebec的末期作品 时钟机关之星充分体现了制作公司的技术力 (翻译: 能在YUV420下正确显示大红大紫的线条 工程师的技术不简单)
令人惋惜的是 榎宫祐老师构想的浩大齿轮世界 似乎没法在有限的画面下完整呈现出来 从结果而言本作销量不足1frt 终究成为了Xebec背上另一根稻草 --by TauZolver
