x265 HDR 编码参数分享  

游客，如果您要查看本帖隐藏内容请回复

,这个是安照 蓝精灵2 来设置的，UHD视频读取的参数是 R: x=0.680000 y=0.320000, G: x=0.265000 y=0.690000, B: x=0.150000 y=0.060000, White point: x=0.312700 y=0.329000；重编码后的视频读取的 R: x=0.680000 y=0.320000, G: x=0.265000 y=0.690000, B: x=0.150000 y=0.060000, White point: x=0.312700 y=0.329000，这个跟上面都一样的了。

向大神学习，可惜电脑不给力，速度太慢。

进来看看，怎么做

世界哪有真情lu

终于有压制参数来压制x265 HDR.我拿个视频试试压制出来的符合UHD SPEC不...谢谢木木大分享

对了，我想请问一下，
--master-display G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(40000000,50) --max-cll 1132,923 --max-luma 4000与R: x=0.680000 y=0.320000, G: x=0.265000 y=0.690000, B: x=0.150000 y=0.060000, White point: x=0.312700 y=0.329000之间是如何转换的了，我查了下资料，是这样说明的：
--master-display <string>
SMPTE ST 2086 mastering display color volume SEI info, specified as a string which is parsed when the stream header SEI are emitted. The string format is “G(%hu,%hu)B(%hu,%hu)R(%hu,%hu)WP(%hu,%hu)L(%u,%u)” where %hu are unsigned 16bit integers and %u are unsigned 32bit integers. The SEI includes X,Y display primaries for RGB channels and white point (WP) in units of 0.00002 and max,min luminance (L) values in units of 0.0001 candela per meter square. Applicable for HDR content.

--max-cll <string>
Maximum content light level (MaxCLL) and maximum frame average light level (MaxFALL) as required by the Consumer Electronics Association 861.3 specification.

Specified as a string which is parsed when the stream header SEI are emitted. The string format is “%hu,%hu” where %hu are unsigned 16bit integers. The first value is the max content light level (or 0 if no maximum is indicated), the second value is the maximum picture average light level (or 0). Applicable for HDR content.

Example for MaxCLL=1000 candela per square meter, MaxFALL=400 candela per square meter:

–max-cll ?1000,400?
Note that this string value will need to be escaped or quoted to protect against shell expansion on many platforms. No default.

--max-luma <integer>
Maximum luma value allowed for input pictures. Any values above max-luma are clipped. Experimental. No default.

所以，这之间是如何转换的，请讲解一下
