If the LUT is converting to BT709 SDR, then you don't need to put st2084 to 709 in z_ConvertFormat, otherwise you would be converting it twice! This is what I use at Sky for PQ to HLG: Code:
#BBC HDR PQ to HDR HLG LUT #From 4:2:2 16bit planar Narrow Range to RGB Planar 16bit Full Range z_ConvertFormat(pixel_type="RGBP16", colorspace_op="2020:st2084:2020:limited=>rgb:st2084:2020:full", resample_filter_uv="spline64", dither_type="error_diffusion") #From PQ to HLG with 16bit precision Cube("\\mibcisilonsc\avisynth\Server\encoder\encoder\Processors\avs_plugins\LUTs\1a_PQ1000_HLG_mode.cube", fullrange=true) #From RGB 16bit planar Full Range to YUV422 10bit planar Narrow Range with dithering z_ConvertFormat(pixel_type="YUV422P10", colorspace_op="rgb:std-b67:2020:full=>2020:std-b67:2020:limited", resample_filter_uv="spline64", dither_type="error_diffusion") |

You're right, FranceBB.
I think this should be correct: z_ConvertFormat(pixel_type="RGBP16", colorspace_op="2020ncl:st2084:2020:l=>rgb:st2084:2020:f", dither_type="none") Cube("C:\Downloads\HDR to SDR\LUT von der rabe\Lut Eigen_HDR to SDR 02.cube", fullrange=true) z_ConvertFormat(pixel_type="YV12", colorspace_op="rgb:709:709:f=>709:709:709:l", dither_type="ordered") Last edited by joearmstrong; 24th March 2023 at 15:20. |

Yeah the last one you posted is correct.
I thought you were just fooling us all, Donald, but I googled it and it's actually really the Squirrel Appreciation Day O_O |

My monitor profile doesn't work anymore in latest version v1.3. Here's a link. It was working at least up to v1.1. Do I need to conform the .cube file to another format?

Means white output. This is what I have been using the past years:
Code:
ConvertBits(16) ConvertToPlanarRGB() Cube("MonitorLUT.cube", 2, true) ConvertBits(8,dither=1)

Looks like a bug in lut_avx2.cpp, as when I replace that with the version from r2a, it works. Intrinsics and assembly are Greek to me, so I posted an issue at sekrit's site:
https://github.com/sekrit-twc/timecube/issues/7 Meanwhile, don't use cpu=2. You can try cpu=3 for AVX512, which seems to work for me. Last edited by videoh; 27th January 2022 at 18:35. |
