I’ve been reading about Brlargg’s composite filter a few days ago, but… How can I apply it?

I think it’s a core setting iirc.

There’s also a ‘video filter’ version that can be applied through settings > video > video filter, but it’s the SNES version, so it works with 256-px width content and gets wonky with 320-px.

I believe there’s also a “custom” version in that video filter list that seems to work with everything. Most of the cores I use have that option baked into the core options except all the NEC cores (Turbo grafx etc.), I think those cores I had to use that custom blargg filter for.

I always love these clear and defined masks in screenshots but I find they kill the contrast and vibrancy of the image. I’m hoping someday, someone finds a creative way to composite the mask layer in a way that doesn’t do that or some invents some kind of dynamic bright opacity.
I probably wouldn’t notice as much if I wasn’t constantly comparing various shaders against each other.

Here are the different mask combos that I like at 1080p, they all do different things to sharpness, color and contrast. I may have adjusted sharpness to compensate on some of these, can’t really remember ATM. Based on my very scientific experiments, the best masks for preserving contrast and saturation are masks 7 and 8, by far. Not sure why. All of these are supposed to look consumer-grade. I’m not a fan of high TVL masks; I don’t see the point unless it has a visible impact at playing distance. All of these are 270 TVL with the exceptions of #2 and #6, which are 360 TVL. I haven’t found contrast/vibrancy to be too lacking with any of these, but it doesn’t hurt to crank up the backlight 
note that these numbers don’t correlate to mask numbers or anything, it’s just how I have things organized.
0 (aperture grille A)
1 (aperture grille B)
2 (slot mask A)
3 (slot mask B)
4 (Lottes rotated slot mask)
5 (slot mask C)
6 (aperture grille C)

I dig variants 0 and 4 - can you share presets ?

All of my presets can be found here:

Hi, May I ask how do you get that effect ? The problem when I use switchres is that it can have heavy glare in bright scenes , even when I reduce the brightens.
I know @tatsuya79 was working on it recently. Hey may have made it more tolerant of resolution changes.

I made most of its parameters customizable but it’s still made for snes resolutions.

Yeah, I think maybe it’s not doing anything. Do video filters work with Beetle PSX? Says it’s enabled in the video settings…
with BLARGG_NTSC_SNES_RGB
without
EDIT: actually, yeah, video filters don’t seem to be working at all.
Here’s SMB3 with the RF version enabled.
@Tatsuya79 that’s cool, how do you edit the parameters?
I’m trying to see if the “custom” version of the filter works as sonkun described, but it doesn’t do anything, either (using Beetle PSX).

Been trying these and something must be up with my setup but I’m getting serious clipping on white and rgb unless I remove Grade from the presets.
Any ideas?

What display are you using? I clipped white a bit to increase brightness, but it shouldn’t be too bad. Can you post a screenshot so we can confirm it’s not a problem specific to the display?
These haven’t really been fine-tuned for color, etc yet.
edit:
this could also be related to TV color levels? I have Blargg’s filter enabled, which I think also enables TV color levels…? Try it with Blargg’s RGB filter enabled and see if that helps.
IIRC, blargg’s filter also adds in some clipping/banding. It’s worth checking out.

with Blargg’s RGB filter

Yeah I’m kinda confused by this; a lot of lost detail in the low end. So now I’m thinking that it’s better to leave the RGB filter disabled? It’s really the edge enhancement/blur/sharpening/whatever that it’s doing that makes the image look good, IMO. If someone smarter than me can figure out how to extract that bit and apply it to every core then I’d be happy, lol. 
Or, is there an easy way to un-crush the blacks, so there isn’t a ton of lost detail while using the RGB filter?
edit: @cobhc2016
For now, you can just leave Blargg’s filter disabled and lower both bright pixel bright boost and dark pixel bright boost (2.00 looked okay on my display). High-contrast edges are decidedly blurrier with this setup though (the main reason I was using the RGB filter was for sharper edges).

It’s on my OLED and it’s better when I reduce the bright boost (which is not really a surprise) but it seems to be blue that is getting clipped more than any other color and that’s still clipped with both bright boost controls at 2.
