maxkill, I think it's obvious that you're in the minority here, and that your opinion on what most people like might not be true. (For an extreme example, I'm not sure anyone wants to go back to the VHS era.) Please drop this pointless argument, no need to be defensive about what looks best to you, no one is telling you that you can't watch the way you want.

@Asmodian
I do not see the pictures with the madvr working scheme on the first page of the topic. Can you return it? Can you add an HDR-> SDR conversion to the scheme? I want to understand if this is done before or after resize.

I found a new host that doesn't watermark the images.
Like huhn I assume it is done at the end, right before the 3DLUT. I don't feel comfortable placing it on an image because we don't actually know exactly when it happens. If anyone has any evidence for when HDR->SDR happens I would be happy to take a look.

After some experimenting with HDR content and "ShowRenderSteps" I have determined that HDR tone mapping actually happens before scaling. This is nice for performance if you do upscaling but bad if you downscale. Tone mapping before scaling might be important to avoid clipping issues after scaling (edit: though that sounds backwards to me...).
I added a new flow chart for UHD HDR content.

I don't care much for processing as i don't want to alter the video, but rather the up/downscaling, rendering etc. I currently have: Chroma upscaling: NGU - Standard, high quality Image downscaling: SSIM - 2D - strength: 100% - activate anti-ringing filter [relaxed] Image upscaling: NGU Standard - very high Rendering - user D3D11 - use a frame for every VSync CPU Queue 128 GPU Queue 24 All off on trade quality for performance I basically want as high quality without messing up the video. I chose these settings (especially the scaling) as i thought they were the best (meaning not the best for me, but best quality of the options available). I couldn't use NGU on very high for chroma as it seems to use up my GPU sadly enough (GTX 1070). The queues i am unsure about, from the explanation i guess CPU queue has a hand in subtitles, and one kinda frustrating bug/issue i have is that when jumping back/forth in a video the subtitles sometimes don't render, so i have to do another back/forth to re-trigger it. It would be awesome if that could be solved, but i don't think many run into it as probably jump around in videos a lot more than normal people do haha xd Thanks |

I think your settings are generally quite good.
Chroma upscaling: I prefer NGU AA, especially for chroma. Even when using NGU sharp I use NGU AA for chroma. I never set it higher than high for chroma, even with a 2080 Ti and in my SD profiles. Very high doesn't seem to improve real world chroma scaling, it may even harm it. So don't feel like you need a better GPU for that. Image downscaling: I actually use SSIM - 1D 100% LL AR relaxed, 2D can be a bit much depending on the content and scale factor. 2D is great sometimes but I like 1D more for most 4K -> 1080p downscaling when I want to watch 4K content in a window. Linear light is important for downscaling. Image upscaling: I like NGU AA very high, especially for animated or non-real life content but NGU AA v.s. NGU Standard is a fairly subtle difference with trade-offs either way. I don't like upscaling and downscaling for scaling factors below 1.5 for doubling or 3x for quadrupling. I also use Jinc AR for upscaling and Lanczos3 LL AR for downscaling after doubling/quadrupling. There is no reason to set particularly large buffers, it simply spikes the IO and CPU/GPU for longer after a seek or on startup. As long as they are big enough to never get frame drops due to background tasks I set them as low as possible. The defaults are quite good and I use 8/16 for GPU/CPU buffers. I also use D3D11 with present for every vsync. One setting you forgot to mention was the frames presented in advance. I found 3 to work best for me on Win10 and current Nvidia drivers (436.48), again as low as possible while never getting presentation glitches or frame drops. 8 seems too high. Dithering is also very important. On my LG C7 and C9 I like ordered dithering but on my previous LCD screens I preferred ED1 or 2. I also much prefer disabling both colored noise and change dither for every frame. In my "Max Quality" settings.bin, linked at the end of the third post in this thread, I set ED1 for "slow" dithering but I actually use ordered dithering for both fast and slow myself. I just couldn't post a "max quality" settings file and not use one of the error diffusion dithering options.

Why is the rendering time significantly longer in OS HDR than in AMD HDR?
Screenshot.

I used ED2 (both options were checked) for ~2 months now and sometimes noticed that something is odd, although I couldn't really tell why (maybe it was the source as well). Now I switched back to Ordered dithering and I'll try to wait for a content to feel the above

Hey there
Can someone help me figure this out! Why is my video concerting to a different resolution? I don’t see any setting with that resolution... The movie won’t really play. A few frames a minute.. |

Please attach images somewhere else and post a link, it takes a long time to get attachments approved here.

I have noticed colored dithering being on before, and been very happy to be able to turn it off, but I couldn't actually say how I noticed or why I cared.

Any reason to choose Lanczos3 LL AR instead of SSIM - 1D 100% LL AR or Bicubic 150 LL AR after doubling/quadrupling since they cost the same performance I think ? Thank you. |

SSIM can even preserve NGU artifacts too well.. at least maybe in ways I would have trouble proving... but it offers no obvious improvements.

But in my eyes NGU Sharp very high 2x > Jinc AR looks better than NGU Sharp very high direct 4x <SSIM 1D. You're right, thanks. Last edited by nsnhd; 19th October 2019 at 03:03. |

Yes you can, simply set luma quadrupling to 'double again'
