New sonkun crt guest advanced hd presets thread

Thank you. Man I feel the same way, for the past day or two I’ve been trying out different methods to try and keep that look but get rid of the ringing effect around pixels but everything I’ve came up with had some other detrimental effect elsewhere. I think I pushed guest ntsc passed its limits to a level it shouldn’t be at lol. I ended up settling for the “FSharpen - Sharpen Strength to 1.00 and FSharpen - Sharpen Contrast/Ringing to 0.25” switch up and now reworking my 4k presets.

Speaking of 4k presets if anyone that strictly uses the 4k presets wants to try the new look I’m working on try loading up a 4k preset from one of the sample packs above then change these settings in the parameters:

Scanline Type: 1.00, Increased Bright Scanline Beam: 1.00, Mask gamma: 2.00 (or 2.20 or 2.40)

Settings 2 im also experimenting with:

Scanline Type: -1.00, Increased Bright Scanline Beam: 1.00, Mask gamma: 2.40 (default setting)

With those settings I’m trying to get 4k to look like my 1080p presets since I like how those look the most. After I’m done messing with 4k I’ll probably tweak the warm/cool presets then start getting everything ready for a full release.

Slot Mask:

Aperture Grille:

Shadow Mask:

@guest.r So I was today years old when I found out there was another Slot Mask settings combination I could use at 4k resolution:

Crt mask: 10.00, Crt mask size: 2.00, Crt mask zoom: -2.00, Slot mask width: 8.00, Slot mask height: 4.00

Works for both Slot Mask

And Aperture Grille

With those settings I can also set the “mask gamma” to 1.00 as well. Using mask 12 with mask gamma at 1.00 and mask zoom at -1.00 gives me this weird “greenish” color tint on the image, with this alternative combination the colors look the way I expect them too. Might end up using these settings don’t know, still messing about.

Now I wonder if there’s a alternative Shadow Mask combination I can use with mask 10 at 4k resolution besides the one I’m currently using with the settings crt mask - 6.00, mask size - 4.00, mask zoom - -4.00.

This is also a good way to get rid of moire patterns in many cases, especially due to curvature and insufficient resolution.

What it does is it raises the TVL and helps the “phosphors” to be better aligned especially with the edges of text and graphical elements.

I actually measured and counted the triads in the arcade version (or it could have been the SNES version on a JVC D-Series) of (Super) Ghouls and Ghosts and Mask 10 at 4K was actually more authentic than Mask 12 at 4K when it came to matching the triad size of the actual screen.

It’s what formed the basis of my Le’Sarsh_4K_Optimized presets as well as my Fine presets and how I was able to have no issues with moire whatsoever when using my CyberLab Special Edition Presets which feature bezels of a similar size to some of Duimon’s TV presets.

I’m pretty sure I shared this info in the forums a while ago.

You can take a look here:

Yes, mask zoom seems to work very nicely with mask 10 with size 2. I would only endorse setting slotmask width on auto, because it works with mask zoom on-the-fly and the presets are much easier to tweak.

A very good alternative is also mask 6, as well as with mask size increased as with mask zoom.

sonkun · 26 August 2024 14:07

I also discovered the mask 6 settings yesterday as well, forgot to mention it. I never knew there were multiple combinations to achieve results. Those mask 10 settings make the colors pop at 4k for Slot Mask and Aperture, I’m definitely going with those settings. The last one I’m dealing with now is Shadow Mask.

I discovered some new settings last night for Shadow at 4k using mask 10, I believe size 4 and I also believe mask zoom at -2. I’m not home atm to confirm my memory. For some reason I’m having a hard time getting the colors to look close to how it looks with Slot/Aperture. I’ll have to play around some more when I get home.

At least I’m almost done tweaking. Once I finish with 4k Shadow settings then I’ll probably play with warm/cool presets to see if I wanna change those up then it’s time to release this baby.

New Version Release (08-31-2024)

Changes Made

Uses guest.r shader version 2024-09-07-r1.
Tweaked a bunch of tint color settings within the “grade” shader to give the overall image a new look. The contrast setting that use to give Linux users a black screen has been disabled. Increased saturation by a bit.
All previous “rf megadrive/composite megadrive rainbow” presets have been replaced with a new setup. Now you can find them under just the standard rf presets and composite “rainbow-artifacts” presets bringing the total number of presets per folder down from 63 to 45.
NTSC rf and composite presets that used the “guest-advanced-ntsc” shader have been replaced with “guest-advanced-hd” now combined with the updated “ntsc-adaptive” shader (brings the colors out a bit more).
4k presets have new crt mask settings (they look better now).
Changed interlace mode on all presets (no more “shaking” screens on interlaced games). Also increased the “vertical filter range” setting in s-video/rgb presets to help smooth out interlaced games/content (Marvel vs Capcom 2 etc).
Switched up curvature screen settings.
Rearranged and toned down brightness/glow/halation settings (still get a bright image though).
Random small changes to deconvergence and rf noise settings.

All images are from the composite preset except Donkey Kong, The King of Fighters 98 and Marvel Vs Capcom, those use the RGB preset:

Grab the pack in the first post.

This update has been a long time coming. This time around I wanted a bit more of saturated image compared to my last pack, overall just wanted to try something new so I hope you all enjoy the new look.

Good Jobs Nice u-normal-rf

sonkun · 1 September 2024 21:07

Thank you. I tried to make it look clean and sh*tty looking at the same time lol. Definitely has a lot of chroma scaling/bleeding going on there.

ynnad4 · 2 September 2024 11:30

hey there, hello again buddy. Thanks to keep up the work into this project.

Is this a new feature being part from NTSC adaptive? I thought it was a new bug but never have seen this behavior before. The Rainbow is only reaching till the top of mountains like you can see in this picture.

This is the RF warm preset i think.

sonkun · 2 September 2024 11:46

I’m assuming that’s part of the design of how the ntsc adaptive shader works. I think it looks that way whether you put the rainbow setting value in the positive or the negative. To achieve that result I put both the “fringing” and “artifacting” settings on 2.00 then the rainbow setting on 1.00.

Try this out to see if it makes a difference, try setting the “artifacting” setting to 0 and leave the other two as is.

@guest.r would probably be able to give you a better answer to this as well.

guest.r · 2 September 2024 12:35

Rainbow effect is currently only enabled on “bar patterns”, otherwise there’s a lot of color artifacting on the screen.

It’s happening by default on checkerboard patterns though.

sonkun · 2 September 2024 13:19

In that case shouldn’t the rainbow effect also look the same in the mountains/tress part of the image above the log along with that small area of tress under the log? Aren’t those areas still considered “bar” areas as well?

guest.r · 2 September 2024 13:22

Not by pattern recognition. Otherwise the screen would be full of false positives.

sonkun · 2 September 2024 13:44

Ah ok got it. Well @ynnad4, I hope that helped explain the situation a little better.

guest.r · 2 September 2024 14:07

I’m testing a different approach, hopefully it will go well…

ynnad4 · 2 September 2024 14:14

those 3 values are set by default on your RF preset

I saw there’s this new value called as MD (MegaDrive?) palette. Is this a new feature from Guest presets ? or you got it from some other additional shader?

I just notice the screen gets a bit more bright.

Also, not sure which one is the feature that triggers this but when moving the character, I see the some vibrating pixels around the grass. Dont know the technical term, but it happens in some recent presets with the Rainbow effect.

Edit:

This NTSC Fringing value is what causes pixels around the grass to be “vibrating”. Do you know if there’s any situation or game that benefits from this feature? Setting value to 0 removes this effect, while keeping the rainbow intact. I used to have a Genesis console with Rainbow but by no means I remember this “vibrating” effect happening.

sonkun · 2 September 2024 15:16

That feature is indeed a new setting that’s apart of the updated “ntsc adaptive” shader that guest.r has incorporated in his guest advanced ntsc shader and in the stand alone “ntsc-adaptive” shader that can be found in the ntsc folder.

But let’s sit back for a little, guest.r above just now said he’s cooking up some new experiment in the lab. Let’s see what happens.

The main benefit I see from it is that it helps “dirty” up the signal and overall image which is exactly what I want. With fringing turned off it becomes too “clean” to me which is what my composite presets are for. I basically want rf to look like sh*t but still kind of clean looking at the same time lol.

ynnad4 · 2 September 2024 15:11

this is a little variant for RF warm in case you may like it.

#reference "aperture-grille/curved-screen/1080p/06-1080p-crt-guest-advanced-hd-aperture-grille-u-warm-rf.slangp"
g_MD_Pal = "1.000000"
cust_artifacting = "1.000000"
cust_fringing = "0.000000"
barspeed = "120.000000"
barintensity = "0.150000"
bogus_deconvergence11 = "1.000000"
deconrr = "-4.000000"
deconrg = "3.000000"
addnoised = "-0.100000"
noiseresd = "6.000000"

Really like the RF presets. They’re so scarse to find around. Even though RF is the most basic cable system you used to get by the early 90s.

Mono audio is mandatory I think to use with RF presets because audio was one way signal through that single cable and I set audio output rate to like 8400 hz to give an extra bad quality audio experience.

sonkun · 2 September 2024 15:00

I won’t be home for a good few hours to test those settings. Mind posting a screenie?
