What about NGU AA low?

It's good for low-res sources which are often low quality in general. For high quality sources like 1080p BDs you likely want to use a sharper mode to prevent blurring of surfaces like red clothing etc.

What do you recommend for 1080p bds?

aufkrawall · 7th September 2017, 20:41

"a sharper mode" would be e.g. NGU Standard medium or high.

Shiandow afair used a 1080p example of red buddhist monk robes or something like that to demonstrate that even for high quality sources the chroma scaler can make quite a difference.

Sounds good! Thanks. What about image upscaling?

aufkrawall · 7th September 2017, 20:55

Well, imho basically the same applies: NGU AA/soft for low quality, standard or sharp for HQ sources. Dunno what I would add to that, at some point it's just a matter of taste.

Performance wise it's a pretty good option if you can't reach NGU AA medium. At that point though I might consider one of the other algos instead, I haven't done any direct comparisons between low and the others but I'm no fan of the sharper algos that's for sure, but it really does come down to your display.. I believe owners of Projectors like Madshi tend to prefer the sharper ones.

That scene doesn't show a huge amount of difference. It's a decent test shot though. There are combo colored/red/black scenes that show large amounts of brightness differences (like the transformers scene I posted earlier in the thread) with different scalers. I want something that looks natural. I'm very happy with what I'm seeing I'm accustomed now to areas where chroma scalers play a large impact in picture presentation so I think I'd pick up when things felt a little off.

Do you know if madshi is using NGU Sharp on both chroma and luma with his projector?
Is it better to keep both chroma and luma in the same family?

No, for chroma upscaling there is no benefit to using the same method as image upscaling.

70MM · 8th September 2017, 06:12

What two do you think might be best to use then for a JVC X9500 projector on a large 140" diag screen?
I like a sharp image without artefacts...

With my 1080Ti card I have been using:
Chroma = AA NGU High
Luma = AA NGU Very high

Asmodian · 8th September 2017, 06:52

Yes those are good, and what I use on my 55" OLED. I have never tested a 140" projector.

I would also test NGU Sharp very high for Luma, on some screens I like it a lot and on some I don't.

70MM · 8th September 2017, 06:58

But are you saying not to have both set the same, say both at AA NGU or both at NGU sharp?

Asmodian · 8th September 2017, 07:39

Yes, NGU AA for chroma and NGU Sharp for luma is a good sharp option.

I have the x5000 and I'm using ngu sharp for everything (high) and the image is breathtaking.

Also, I'm using some sharpening options (I don't remember wich ones, I will tell you if you want) and a little bit of denoise 3d (ffdshow raw), I have an 120" screen and I fail to see any artifacts and as I said, the image is breathtaking (with 1080p sources scaled to 2160p23hz).

As you can see I also like clean sharp images (like in the theater nowdays).

70MM · 8th September 2017, 08:17

Which sharpening options do you use? What is denoise 3d (ffdshow raw)?

Dorohedoro · 8th September 2017, 08:27

I will tell you my sharpening options tonight , I'm not in my house right now. Ffdshow is an old filter that will give you some problems (none for me so far) specially if you want to use hdr (I'm not using it yet).

Under the ffdshow options you will find some denoise filters, I really like denoise 3d because it will help you get rid of that ugly grain of some old movies (I dont don't like grain) without losing to much fine details. Until Madshi add some denoise options in madvr, ffdshow raw is a good option for me.

For a PC monitor I find NGU Sharp medium a little bit too sharp, NGU standart behaves a little more natural.
