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.

Re: HDR -> SDR conversion
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.

Re: fulldepth=True
Hi Is is means DGSource won't "upscale" bitdepth from 8bit to 16bit if i'm using 8bit source Some of our encoder want to handle banding and some other fixes in 16bit before outputting a 8bit video. If DGSource won't "upscale" the source then I may need to process it with extra filter or something s...

Re: HDR -> SDR conversion
Thought it was common knowledge that banding is caused by the down conversion from a higher bit master to 8bit? But anyways.. Here is an example of 8bit vs 16bit vs DGHDRtoSDR. I could not use DGHDRtoSDR in this test for 16bit cause I am sure its going straight to 8bit. That is why I asked if that i...

Re: HDR -> SDR conversion
I was under the impression that the DGHDRtoSDR plugin automatically converted everything to 8bit. Is this not true?

Re: HDR -> SDR conversion
Down converting to 8bit causes banding. You can't just up convert back to 10/16 and its fixed.. the data is lost. A plugin would be required to fix the banding.
Can't encode in 10bit basically. Properly.

Re: HDR -> SDR conversion
Is it possible to have your plugin not take everything straight to 8bit? Like a bits="10" command or something?

Re: HDR -> SDR conversion
You guys are trying to solve a tonemapping problem that cannot be solved. We cannot see what an UHD clip is suppose to look like because we don't have the proper display for it. What we have is a glimpse of it atm. Should just include all the tonemapping algorithms in the dll and let people choose w...

Re: HDR -> SDR tonemapping
Was never a fan of Hable but I did like Reinhard but it had issues.. Looks like mobius solved alot of those issues.
The amount of work you put into this is incredible..

Re: Decoding Error / Artifacts
I actually found the problem before getting a new card.. one of my avisynth plugins was out of date on the PC causing stability issues.. copied all the plugins from the 1070 PC over and all is working.. Guess this is considered solved and wow I am jealous of your 1080 Ti

Re: Decoding Error / Artifacts
I think the problem is the 950.. My 1070 doesn't show these errors.. Going to pickup a new video card and see if the problem continues.

[SOLVED] Decoding Error / Artifacts
I am getting decoding errors on some HEVC 10bit videos. I only see this happen in certain spots. I am using a Nvidia 950. Maybe I can send you a sample of the video. Going to test on my 1070 later today. Been trying to convert UHDs to 1080p Sdr encodes and i keep getting these decoding errors. Runni...

Re: HDR -> SDR tonemapping
I feel like without an HDR monitor as a reference, every setting would be a guess-timate. Trying to pick the right setting is quite a challenge. :D HDR color mapping is set by the user.. and in the case of Monitor / TV's the manufacturer LG, Sony & Samsung etc.. So there is no correct way.. It's al...
