Make sure you have the latest Avisynth+ otherwise 16bit will error out and display nothing..

Thank you, Dion.
Here is build 1.8, which adds a fulldepth parameter to output 10-bit SDR stored in YUV420P16.

BTW, you have tm="mobius". That is not valid syntax for build 1.7, so I suppose you used an earlier
version.

DGHDRtoSDR 1.9 is released. It adds Vapoursynth native support.

Have you ever considered making an HDR to SDR app for the Nvidia Shield? It has an Nvidia GPU in it and one thing it lacks is an HDR to SDR app that can hook onto Plex or Kodi or some other popular video apps.
Could even charge for it an probably make some decent bank.

I'll look into it when current projects finish up. Thank you for the suggestion.

Stark image is from the 1080p bluray.. Not the UHD..
UHD and 1080p BD's do not have the same color.
and on top of that you have never seen a UHD in it's native form.. So you have no idea what Tonemapping is correct. The quest for a perfect SDR tonemap is impossible right now.

Perfection is a highly improbable result at any time.
All we can hope for is good enough > good > real good > darn, that is good
DGHDRtoSDR is already in the real to darn range

Just a note about the .rar file not opening in 7zip commandline,
Per
http://forum.doom9.org/showthread.php?p ... ost1853939 when I try to manually use standalone z7ip to even list the rar file, it fails.
Would it be possible to consider using .zip or something ?

I'll look into it tomorrow. Thanks for pointing it out. I used to always use ZIP but then I saw lots of people using RAR.

"strange hue"
Not a really precise formulation but I can look into it if you provide me with an unprocessed source stream sample. I can't do much with JPGs.

Every my tested video has same problem. I can see almost similar result only after appending Tweak(hue=10).

Please try out this version:

I added some hue correction for the gamut mapping. We'll never exactly match other solutions. What I am aiming for is reasonable results for most streams and fast processing in CUDA mode.

I see similar problem with the colors. It is probably due to the Hable operator implemented with DGTonemap plugin with its dafaults.
At least, I’ve seen same results with ffmpeg tonemapping filters.
Three of above screens are results of Hable tonemapping. The fourth is from the source UHD .hevc.
Working with 240 frames cut from the source Gladiator 2000 UHD I've encountered two more problems:
- DGDecNV(), when works, processes 236 frames.
Code: Select all
>avs2yuv64 -depth 10 -raw DGTonemap.avs - | x265-64bit-8bit-2018-10-08 - ...
yuv [info]: 1920x1080 fps 24000/1001 i420p8 unknown frame count
raw [info]: output file:
...
x265 [info]: HEVC encoder version 2.8+74-fd517ae68f93
...
x265 [info]: tools:
avisynth 16-bit hack enabled
DGTonemap.avs: 960x1080, YV12, 10-bits, progressive, 24000/1001 fps, 236 frames
encoded 236 frames in 293.53s (0.80 fps), 59210.41 kb/s, Avg QP:16.28
If I use FFMS2() as a source instead I have
Code: Select all
>avs2yuv64 -depth 10 -raw DGTonemapMod.avs - |
...
DGTonemapMod.avs: 960x1080, YV12, 10-bits, progressive, 24 fps, 240 frames
encoded 240 frames in 314.47s (0.76 fps), 58830.89 kb/s, Avg QP:16.23
- HDR2SDR plugin doesn't work properly.
It process more than 500 frames and I cancel it. Seems like a program loop.
The result seems as if color channels' frames are overlaid.
Working environment
Window 10 Pro v.1803 Build 17134.345
GeForce GTX 1050 Video driver v.398.82

There may be a good reason for that. If you link me to your cut stream I can look into it.
HDR2SDR plugin doesn't work properly.
I don't know that plugin.

Tonemapping isn't a trivial task and the operators least at their defaults aren't universal.
I've just found a JOHN HABLE's publication at
http://filmicworlds.com/blog/filmic-ton ... er-curves/
proposing
Filmic Tonemapping with Piecewise Power Curves.
Here is his source code
https://github.com/johnhable/fw-public
I think it would be nice if we had this model implemented as aa AviSynth.
