you goes into the funimation direction, overbrightness, oversaturation or too much vibrant , even the color cast is stronger in the result
Or a much less tinted Final Chapters direction. Auto white balance is a real hurdle, manual for so many frames is a lot of work.

so you choose to run away and overbright to "hide" the things? it's not really color correcting and Funimation already do that in their box

Only thing I'm trying to hide is dithering.

but you talk about the white balance that is a pain (we all know that here), it's just the way you talk making me answering that cause of that you did that

but anyway it's not a less tinted , yours is on the left and tint is stronger

Agreed. Whatever headway was being made earlier seems to have taken a step backwards. This is not good at all:
Orange Bricks galore.

I thought orange bricks were hated cos of detail loss, turns out it's the colours too looool, and I'm counting crushing the blacks and whites as detail loss.

To lay down what's wrong with them, here's the shortlist.
* Loss of detail due to the DNR removing grain & animation lines getting caught in the crossfire.
* Cropping to 16:9.
* Color brightening to hell & back that makes them look bleached.
* Color saturation that makes the overly brought colors even more bad
* Smearing to remove the grain

That's basically it.
Only dubs that matter are DB, Kai, & Super. Nothing else.

Well, I liked the intense colours in my screenshots. I could do another saturation and value remap shader to make the colours look less 'orange brick' and then I'd basically have two versions.

Plus I had an idea to fix the white balance better (thanks to hakaibills93's screenshot).

it's only a screenshot, how to fix is not inside, about colours i really think you should give up "intense" colors, it's i am sure what everyone are saying here to you

The screenshot and what you said gave me the idea. Re. the colours: decisions, decisions.

After remembering a post I saw on Discord a while ago about NTSC-J having a different white point to NTSC (D93 vs D65), it got me thinking about the colour space of DBox.

So I found the RGB for D93: 206, 226, 255 (I checked other sources to get an exact value but if you go down to 9300K here http://www.vendian.org/mncharity/dir3/b ... color.html, you'll see it's pretty close) and then I white balanced an image of Black, that value and white:
Image

And put those points in a remapping shader (using PC.601 to convert to RGB because it did the best job of toning down the crap in the hair + it was the full range) and got these results from Z E291:

Image

Image

Image

I put the shader in my Github: https://github.com/crabshank/HLSL-Resha ... remap.hlsl

I tried using the Dr Dre's Color Marching, with Dragon Ball Kai as reference. But the only problem is the artifacts:

I don't claim to be an expert but I've played around with Dr. Dre's tool a bit. I'd recommend trying turning up the smoothing parameter, I was getting artifacts and that seemed to fix it.

Zero context, zero setup. Its in NO way meant to be seen as a "beginning point" for ANYTHING other than the next story arc. It flows precisely and fluidly from where things left off in the aftermath of the 23rd Budokai and mostly hits the ground running from there without really stopping to look back. You're plopping someone into the middle of a book starting at chapter 195 out of 519 for absolutely no good goddamn reason, with very minimal opportunity to look back at much needed context and character/story growth.

I did a second method of changing the white point to D93, using an RGB<->Lab conversion (PC.601; Right is D93):

It imparts some heavy blue tint, but it did change the tint. It would be the first stage in the process.

I just (re-)did a remapping version of my RGB <-> Lab conversion shader for NTSC -> NTSC-J and here're the results (mine on right):

Image

It doesn't have the strong denoising effect that the RGB <-> Lab conversion does, but I feel like it's less destructive. So: decisions, decisions.

The shader's here: https://github.com/crabshank/HLSL-Resha ... remap.hlsl

N.B. the primaries for NTSC and NTSC-J are the same, so I didn't have to worry about that.

After being stuck on white balancing for ages, I think I've found a solution, custom xy points in CIE 1931.

Image

Pretty much all colour spaces are defined in terms of the above graph, and white points (e.g. D93, D65 etc.) and defined by xy coordinates on that graph.

So, in my shader https://github.com/crabshank/HLSL-Resha ... Point.hlsl, all you have to do it set the two values in Customxy:
Image

And if you have debug on, change until the grey areas go black (it amplifies small differences):
Image


Image

Image

Image

Image

Image

Image

Some parts are just different though...
Image

Just need to get a crosshairs GUI to work now...

N.B. I'm working in PC.601.

Latest CC is E284:
https://youtu.be/k72SKpbmIwg

This is white point change, greyDitherSdv 7, crushing v1 0.06 hues and saturation (matched to uniform gradient with no gamma).

No S-curve on this because it was giving intense artefacts.

All in Rec601 because PC.601 looks washed out.

I also changed the audio technique, but I didn't do a cutoff limit so it equalised all the frequencies. That's why you can hear the buzzing of analogue TV.
