本片采用日版 BOX 原盘压制，原生分辨率是 720p。之所以没有采用码率更高的意大利版，是因为意版只是用了更锐利的拉伸算法和锐化处理，原始分辨率并没有区别。与剧场版的处理相似，我们通过逆向拉伸重构解决原盘拉伸导致的锯齿和振铃问题。原盘部分场景有色度色带，我们通过亮度分离，做了有针对性的抗色带处理。最后，我们进行常规的自适应降噪以控制码率。
This film was encoded using the Japanese BOX source, with a native resolution of 720p. The reason we did not opt for the Italian version, which has a higher bitrate, is that it merely employs a more aggressive upscaling algorithm and sharpening process. The original resolution remains the same. Similar to the treatment of the theatrical version, we resolved the aliasing and ringing issues caused by the source's upscaling through descaling and reconstruction. Some scenes in the source showed chroma banding, which we specifically addressed through luma separation for targeted de-banding. Finally, we applied conventional adaptive denoising to control the bitrate.

To give some context: the ITA BD was sourced from HDCAM tape due to a shortage of HDCAM SR tapes (2011 disaster). HDCAM is 1440x1080 with lowpass filtered chroma. Some filtering was done to improve the quality, but there's only so much that can be done with a compromised source. Other international releases also used the HDCAM source, except for the 2021 UK BD.
