Q:BD制作中犯了什么错误?
A:没有将原始的RGB full range数据正确转换到专业视频终端分发所需要的limited range数据,导致画面出现了过暗/过亮问题
如果对此有兴趣可以参考以下文章:
https://www.thepostprocess.com/2019/09/24/how-to-deal-with-levels-full-vs-video/
实操中更大的可能性是本身渲染最后导出的数据即为full range,TV和WEB被校色彩条自动校正了,偏偏BD用的是工匠手压x264直出的,缺少了校色这个步骤
这个错误不算少见,但大部分都会被自动机制校正掉。上次见到还是上次大概可以追溯到之前的《月色真美》,也正是这部片后不少动画流媒体网站也添加了校色彩条这道工序。

值得一提的是和其他很多犯了明显错误的碟片一样,他又是只有NCED是正确的
也不知道是不是因为NCED是最后烧碟的所以发现后可以纠正,而前面的就不管了

Q:为什么会有limited range?
A:模拟时代为了减轻信号长距离传输带来的干扰形成的产物,属于“祖宗之法”

Q:这意味着BD质量很差吗?
A:对于压制而言BD的画质其实更好了,因为full range可以容纳更多的范围,在BD的8bit YUV下可以略微提升画质。

Q:如果播放器其实可以支持full range,为什么压回了limited range?
A:几乎所有播放环境的默认设置都是针对limited range的,使用limited range可以防止在一些比较小众的播放器PotPlayer[em198]上出现无法正确识别的问题。
而且10bit SDR YUV即使是在limited range下也可以完整覆盖8bit RGB,并不会降低画质。


Q:有办法修复原盘的问题吗?
A:在不重压的前提下可以通过补丁方式强制修正视频的flag,但由于BD规范中并没有相应的定义,经测试相当一部分播放器(包括PS4/PS5等保有量较大的机器)依然无法正确识别。只能保证PC端大概率可以正常观看

Q:如果压几年yuv444p10le可以倒逼厂商支持硬解,full range有希望吗?
A:你在想屁吃他们甚至不愿意放弃23.976(
