Looks like something was a bit off with colors and uneven scanlines. Fixed that now:

Hey @hunterk what do you think about adding the bw trinitron masks to the subpixel_masks header?

I love how they look and don’t tint the colors on RGB LCD regular monitors.

   else if(phosphor_layout == 22){
      // aperture_1_3_rgb; good for 1080p and lower 
      vec3 ap4[3] = vec3[](black, white, white);
      
      z = int(floor(mod(coord.x, 3.0)));
      
      weights = ap4[z];
      return weights;
   }

   else if(phosphor_layout == 23){
      // aperture_1_4_rgb; good for 4k 
      vec3 ap4[4] = vec3[](black, black, white, white);
      
      z = int(floor(mod(coord.x, 4.0)));
      
      weights = ap4[z];
      return weights;
   }

mask 22 on 1080p screen:

[monoculero]

hello, can you share it again please? thanks!!

[Hyllian]

If you’re talking about the presets above, it depends on @hunterk adding those masks to subpixel_masks.h. Otherwise I’ll have to insert those masks inside my shaders and it’ll take some time…

[hunterk]

Yeah, sure, we can add those.

Can anyone describe the pixel layout for them? like, is it just black, white? Or white, white, white, black, etc?

[Hyllian]

Don’t no if I understood your question, but the code for the masks are these:

else if(phosphor_layout == 22){
      // aperture_1_3_rgb; good for 1080p and lower 
      vec3 ap4[3] = vec3[](black, white, white);
      
      z = int(floor(mod(coord.x, 3.0)));
      
      weights = ap4[z];
      return weights;
   }

   else if(phosphor_layout == 23){
      // aperture_1_4_rgb; good for 4k 
      vec3 ap4[4] = vec3[](black, black, white, white);
      
      z = int(floor(mod(coord.x, 4.0)));
      
      weights = ap4[z];
      return weights;
   }

[hunterk]

oh, you already have them ready to go <3. Sure, I’ll get it pushed up real quick.

I still need to update your shader to match your recent additions, but that’ll take more time. I’ll probably get to it this weekend. I need to do guest’s, too…

[Hyllian]

Don’t update my shaders on repo yet, as I’m working on them lately. Wait for when they’re more stable among releases, so you don’t waste your time. I think I need to rewrite some parameters, cut useless or obsolete options in the next weeks. I only need you to update the two masks in subpixel_masks.h so I can share the presets here.

[hunterk]

ah, cool, thanks for the consideration. Just ping me when it’s ready, then

I just pushed up the b/w masks but I am not able to test it, so just let me know if I typoed/broke anything: https://github.com/libretro/slang-shaders/commit/14721633b2afc91673487906f04752b9bc1b46c2

[Hyllian]

Tested here and it works as expected.

So I just included the two presets with these trinitron masks: crt-hyllian-22-06-10 - slang.zip

Some shaders were updated too as the parameters range should be increased.

OBS: only works if you update subpixel_masks.h from the repo. See hunterk’s post above -> Please show off what crt shaders can do!

@Nesguy

Updated presets. Spent a lot of time trying to get sharpness and brightness juuuuust right with the NTSC shader, and although these things are never “done,” I feel this is good enough for a release.

edit: forgot to set mask clipping to 0.00, fixed. Screenshot doesn’t reflect this.

I took a look and tried to download this repo and I get an empty folder…

I have updated my Reshade github repository with some shaders which allow nice mask and other effects.

GitHub - guestrr/ReshadeShaders

The 2xScaler can be used for aa-smoothing, but will probably add a simpler and faster shader.

Example:

[Nesguy]

Oops. Should be all set now

[DevilSingh]

@guest.r Thank you for the 2xScaler shader. Now my VHS shader doesn’t need to be blurry as shit to hide low res textures!

VHS Shader (with 2xScaler) :

VHS Shader (Old) :

RAW (No shaders) :

Any interest in making a 4x or even a 8x version? Will they look any better than the 2x version?

[guest.r]

Lol it’s been a while with these shaders, i’ve probably meant “2d” instead of “2x”. The kernel itself is arbitrary though and doesn’t require a specific rendering ‘multiplier’.

[tailslol]

im sad most of those great shaders are based of ntsc svideo or composite.

i think rgb scart with pal and secam need some love.

@DevilSingh

@guest.r Thank you for the 2xScaler shader. Now my VHS shader doesn’t need to be blurry as shit to hide low res textures!

VHS Shader (with 2xScaler) :

Wow, this is a great improvement!

Is this in slang? Or Reshade? Or Both?

[DevilSingh]

Thanks. My VHS Shader is ReShade only. I’m not sure RetroArch has all the shaders I use for this effect.

Oh, and if you were asking about the 2xScaler (or 2dScaler) you’ll have to ask @guest.r for it.

[hunterk]

The NTSC/PAL effects are currently back in vogue but are thankfully quite self-contained. Just replace those passes with the ‘stock’ shader.
