Yeah NTSC filters have really grown on me.

After giving it some more thought almost exact results can be achieved with stronger scanlines, no need for a special code or extra parameter. The only difference between this and a very rigorous approach is maybe a very small amount of general vertical image shift.

Hello, the sharpening works great. On my laptop with a 2060 NTSC Blend mode 1 causes what looks like tearing on the letters in Super Mario World. I had other strange artifacts in games that I think were also the cause but I can’t say for sure.

I could reproduce. Some additional color clamping was needed.
New Release Version (2021-07-16-r1):
Notable changes:
- small fix with NTSC mode 1.0

Get them hot fix patches!!!

As an experiment I re-created my softer more masky preset from Guest Advanced with the GV NTSC preset. I can getting nicer dark outlines (especially in 8bit games) with the NTSC and I abuse the gamma for a stronger mask in the darks. The sacrifice is details get mushed. Which do you guys prefer?

New Release Version (2021-07-17-r1):
Notable changes:
-
NTSC resolution scale option added. While true scaling tricks are possible i managed to tweak the ntsc shaders into simulated scaling, so the 1st pass x - scale can stay at 4.0x. Default value for the control parameter is 1.0 and the effect is the same as with prior versions.
-
Raising the value produces a sharper, cleaner image, but dithering becomes visible. Anti-dithering passes can still be used as prior shaders in the preset though.
-
Lowering the value can be useful for higher resolution input resolutions, for the ‘NTSC look’.
-
I didn’t find any new issues, but feedback is, as always, welcome.

The first one looks better to me.

Imho, the first looks better almost everywhere with two exceptions imo.
The lamp posts (lamp lights w/e), and the fence both look better in the second shot imho, idk about the rest of the image, nothing “technically” wrong with it.

The scaling is neat. Here is Venom Advanced vs Venom NTSC. It’s just interesting to see what happens when you blur one and sharpen the other. First is advanced, second is NTSC.

About to look at those pictures so will add an addendum to this comment but it’d be interesting to see some ps1 shots messing with scaling and with/without ntsc as well, imho. (Just thought that’d be “more interesting”).
Edit: So… liked the shots. Uhhh, I don’t really have much to add, the sharpend ntsc (composite?) is interesting looking tbh, probably meh for dithering tho.

The shots are more to show the difference/similarities now with all the options. The NTSC filters give extra dark shading so you get thicker black lines. Both options provide different ways to beat up the image for a more natural look.

I tested the new ntsc options with the ps2 core and the code translates to the hlsl without problems, which could cause problems in general, since even a shader warning stops the shaders from being used.
The new pseudo scaling works quite well, the values are best lowered with increased internal resolution.

I think this topic passed some time ago also, but maybe it has some of your interest with the updated color spaces (“modern” addition).
Would you be interested to add a feature or create a separate shader in which clipping of a color profile versus the chosen color space can be displayed? For example with some preconfigured fixed color replacing the clipping colors?
I would like to measure my own monitors color space and would be interested to know how well it can display the CRT color profiles without clipping. Would be fun and useful to see in realtime which games and when are clipping colors or not.

This is a nice idea and i produced a simple debug code. It should work nicely with conjuncture with the new brightness parameter. The brightness parameter works properly only when lowering brightness and it can help to determine the amount of clipping.

Otherwise LUT’s shouldn’t clip colors in vanilla usage, color profiles can.

Tweaking a consumer-grade crt preset based on a photo of a 13" slot mask TV.
What’s the best way to keep the right hand (the hand holding the sword) bright, while keeping the black outline around the sprite as solid as possible? There must be some tricky combination of sharpness settings that will accomplish this.
Here’s the photo for reference
Maybe someone can improve on this further?

Thanks again for creating this, very useful.
I’m only running into a thing I don’t yet understand.
If I create a custom color profile that is exactly sRGB, apart from red being that bit wider, then when using this color profile in combination with setting sRGB color space I would expect the debug to only flag red as clipping (out of gamut) on the 240p color bar test, but instead it shows green and blue clipping on the last bar (but not red!)

Any idea what might be going on?
I’m using this matrix where primaries and white point are sRGB except for red extended one notch. When using this color profile in combination with color space set to sRGB, the debug feature shows green and blue clipping, instead of red.

First is your settings, the second mine. Some games definitely show are stronger black outline than others. I wouldn’t say mine is brighter though but perhaps more contrast.

Looks good but the mask is too fine, and too bloomed out compared to the photo. But looks good as far as sharpness and color/brightness goes.

I have to do weird stuff to guest-advanced to get the mask to look like the photo. I altered mask 7 to darken every 4th pixel, you have to replace the pos.x number with a 4 and then the 0.5 with a 0.75, or something. But this looks too fine in some areas. Maybe there should be a variable mask width option (it would require a new mask, though).
