Is a dedicated graphics card pretty much always required for NGU upscaling? I’m a fan of the Intel NUCs, but would they prevent me from using NGU Sharp to upscale Blu-rays to 4K, with a few other features like debanding? Does a Celeron or i3 with a Nvidia 1060 out perform a i7 NUC with no dedicated GPU? I’d like to buy a new NUC for my next HTPC, but if a i7 version is required to use NGU and other features, or if it’s not possible with any NUC, I’d like some suggestions.

it's not possible with any current nuc.
i ditched mine and got a zotac zbox en1060k, ngu sharp, hdr.. work flawlessly.

I'm having a problem getting madVR to play a blu-ray with the "top and bottom" format. |

I know this is nooby but i've two questions, i use mpc be, lav and madvr.
Now, i think this is some sort of zoom settings in the madvr settings. I'm watching a move right now, i'm on 16:9 monitor and movie is 1:85,1. So i've a little black bars on top and bottom, just a few pixel. 1- In some scenes there are the records of an old camera, just a vertical image showed and black bars left and right. During these scenes the video is fitting the screen, like zooming, to perfectly 16:9. Just to turn back when the scene ends. Why? What options take me to achieve this? 2- In zoom control in madvr can you explain to me what the option "disable scaling if image size changes by only:". I'm newbie :/ Thanks!

By the Benchmark , It is as powerful as the GTX1050TI. And I think intel must use it for the new NUC |

which is rumoured to be a polaris card so you should wait and see if it has the same problems as polaris.
and to be totally honest i'm not sure if is possible to cool these chips silently in a nuc factor case the GPU alone will have a TDP of 60-100 watt add the CPU to that and you have quite a hot chip... a g4560 and a 1050 Ti is a cheap solution for a working HTPC. |

In some future version I'm going to switch to D3D11 everywhere, then I don't have to share textures, anymore, which will probably improve the situation for Intel GPU users. However, this will mean losing compatability to XP and Vista. Quote:

It's not a big surprise, though. I've been told that often UHD Blu-Rays are simply upscaled using Catmull-Rom. It's not really hard to beat that. Quote:

Next step is rendering: You can make a Kaby Lake GPU render UHD movies smoothly, but I'm not sure if it works with the default settings, you may have to tweak it a little to get it smooth. Any Polaris or Pascal GPU should have no problem with the default settings. Difference between min and max settings in madVR is relatively small if you don't need to upscale, and if you don't have a need to use algorithms like "reduce compression artifacts". When doing upscaling, or when playing heavily compressed videos, higher madVR settings can bring a very noticeable improvement. Quote:

You may want to try using RCA instead of RRN, it seems users like RCA better for some reason. But if your main goal is to reduce grain, then I suppose RRN might be the better choice. Quote:

I can see copy-back being problematic for 4Kp60, but shouldn't it still work ok for 4Kp24? Quote:

Banding should not occur, as long as you don't disable madVR's dithering (which you should NEVER ever do). If you still see banding then that would indicate that something goes wrong either during decoding or scaling. I'd suggest to try disabling anything DXVA in that case, as a first test. Quote:

You can try LAV nightly with "D3D11" decoding as an alternative. Quote:

It's always somewhat problematic if the GPU driver does some modifications behind madVR's back. Direct3D doesn't support 12bit rendering. I can only render at 8bit or 10bit, but not at 12bit. Now if the Nvidia GPU driver stretches madVR's pixels from 8bit or 10bit to 12bit, that *usually* shouldn't produce problems, but who knows? Hmmmm... Have you tried switching your projector (and madVR) to 0-255 instead of 16-235? Maybe it works better that way? Quote:

What is the easiest way to reproduce this problem? Quote:
Is that your personal opinion, after having carefully compared the two algorithms with various different test videos? Or are you just reposting what some random guy on an anonymous forum posted, without providing any comparison screenshots? Quote:
As mentioned by heiseikiseki, Intel seems to plan to replace their internal GPUs with AMD soon, so maybe Intel NUCs might do the job then. But the GPU chip alone won't be enough, we also need fast VRAM, and ideally 4GB+ for 4K. Quote:

Although maybe a "trade quality for performance" option would be a solution? |

This will probably seem like a silly question, but how do i make proper screenshots with madvr/mpc-hc? I've tried the f5 function in mpc-hc but they are coming out much darker than the actual video when viewed in eg paint. A screenshot taken using an hdr to sdr 3dlut especially obvious, the saved image is much much darker than the video

HDR -> SDR is a complex topic. I'd suggest to first sort out simple SDR screenshots. Only once that's done and properly working, looking at HDR -> SDR screenshots makes sense. For SDR screenshots, please compare F5 with PrintScreen. Is there a difference? You can configure F5 behaviour in the new madVR "screenshots" settings page. |
