ShanaEncoder转码H265 色彩变淡
先上对比图用的预设是 论坛下载的这个预设
hevc h(x)265 8bit 10bit_h265编码1080P 10bit crf23 Mkv格式 profile=Main10@L5.1@High+
后面再贴吧看到一个帖子也说这个色彩问题有人说到 加入参数 -color_range jpeg 或-color_range pc 试试 也没用
查了一下百度，发现有几个参数，换上-color_range mpeg -pix_fmt yuv420p 转码出来的颜色一致了，但又遇到一个问题。

请问一下这个是哪个参数原因导致的，关于后面加的两个参数 如果只有 -color_range mpeg转码出来的还是颜色淡，必须得加 -pix_fmt yuv420p 才有用。
看输出信息都是YUV 420 Limited，按理说应该没关系，，而且输出也是10bit了，个人使用目前没有遇到过此类异常问题，等个大佬解答 -color_range mpeg -pix_fmt yuv420p10le

输出是10bit的话 颜色就会变淡，加上参数颜色正常 但就会变8Bit
3楼大佬参数添加后也无效，感觉只要变10bit 就会颜色变淡。 741861943 发表于 2022/5/2 18:52
-color_range mpeg -pix_fmt yuv420p10le
大佬，添加这个参数后 转码出来确实是10bit，但颜色就变淡了。
其实更准确的说应该是泛白，黑色底比较明显。
先看看你快速设置里是不是把亮度，对比度调过，如果不是这问题的话我给你解决方案 https://blog.csdn.net/yue_huang/article/details/77164579
http://www.6miu.com/read-426016.html 你自己研究下吧 问题解决，原来是 我播放器解码问题。。。{:123:}{:123:}
辛苦各位大佬了
