NEEDS MOE JXL

Oh, that tld actually is intended specifically for https://en.wikipedia.org/wiki/Moe_(slang)

oh i never knew

In previous discuss _wb_ say some manga,drawing content not suitable DCT A little curious, what drawing features suitable DCT? and what drawing features suitable non-DCT lossy? Like this gold hair anime girl image, this drawing suitable DCT?

isn't the crisp edge equivalent to step functions, which need the infinite bandwidth?

(which makes Haar transform appealing for non-photographic materials AFAIK)

Hard edges between solid color regions are kind of expensive for DCT and cheap for other methods like even simple RLE

I compare jxl lossy and avif lossy for anime,drawing content, in previous manga case(file size inflate issue), even I increase option sharpness to 3, av1 file size still not too much affect. I guess av1 probably use local palette on whole image, and not use DCT for those content(hard edge,line)? but for grain or tiny detail av1 need lower q to preserve those content.

Av1 has palette blocks, they can do up to 8 shades per channel (so up to `8*8*8` colors, but has to be at most 8 different shades each of Y, Cb and Cr)

I tested Haar-like transform (lossy modular) before, lossy modular Q95 and 90 is good for drawing, but can't compress too much for file size, if I compare other lossy method.

For now still have a lot of anime,drawing convert to jpeg(DCT), if jxl can implement some improve for those content, that will be really useful.

how desirable is a bot that posts embed links for jxl files?

Going to flash android 12 on my phone. Let's see how avif works on it

Please test if more than yuv420 works. On my Android 11, only subset of HEIF/HEIC images works. I don't know how complete AVIF support in Android 12 is

If it's libgav1, so software decode, I would expect it to have no problem with 444 and 12-bit, but I dunno. The real question is if it will still work once hardware decode gets used...

<https://mangadex.org/title/259dfd8a-f06a-4825-8fa6-a2dcd7274230/yofukashi-no-uta> liking this manga quite a lot so far

I sense that it is time to listen to https://youtu.be/yO7MWuJ7zLA again

~~Canine?~~ (realized that K-9 *is* canine, in the police)

Android heif is stupid, it can't even decode 8bit 444. 😮‍💨

Does it use hw decode?

What a stupid file format, doesn't even look better than mozjpeg but file is 2x size of mozjpeg

Idk, how to find that?

No idea, but maybe there are patent reasons for using hw decoding only, and it would explain why 444 doesn't work

Or maybe android just does HW without software fallback.

yuv420 landscape pictures look bad. Who thought it was a good idea to use 420 by default

My macbook pro does the same thing btw: 444 fails to decode

So in practice, heic is just like webp a 420 only codec

And I suspect avif is going to be the same once hw decode becomes common

So my only hope is jxl for good pictures. ( ･ั﹏･ั)

Video codec designers, and some bandwidth-obsessed web perf people

420 <a:FrogStab:821038589345136682>

Atleast it should decode 444 on software.

I think I managed to generate an HDR HEIF, but my iPhone and iPad (which don’t have HDR screens) don’t seem to tone map it so the highlights are clipped

Looks good on AOSP gallery app and Google photos

wont open on my phone :<

Android 9?

I have android 11

tbh on very high density screens like mobile phones it may be hard to notice... (IDK yet, need to check still)

I think it might be ignoring the colorspace information altogether, which happens to look okay anyway because it’s P3-HLG

(and not just okay but indeed better than whatever iOS is doing)

the use of P3 primaries means that if that information is lost / ignored, and the colors interpreted with Rec. 709 primaries, they aren’t as desaturated as if it was encoded with Rec. 2020 primaries instead

Ok. Could you make one without p3?

I wasn’t able to 😅 `CGColorSpace(name: CGColorSpace.itur_2100_HLG)` returned nil, it only worked with `CGColorSpace.displayP3_HLG`

but maybe I missed something obvious

it was my first time writing anything in Swift or with Core Image

what I can do is send a PNG or JPEG without ICC profile to see if it displayed the same

11 too

and this is with an ICC profile with P3 primaries but sRGB transfer function instead of HLG

I see blank pages in chapter 8.5.

Have you finished reading it?

8.5 are extras

So it's useless?

Unnecessary for story?

usually .5 "chapters" are unnecessary for story, yes

Okay

sometimes they include some extra mini stories or author's drawings, etc

its kind of marking used for "inbetween chapters content"

ones at the end of volumes can include content from anywhere of volume

in this case these blank pages were probably used as chapter separators

twitter's algo favours drama and right-leaning politics have more of that, yes

the new 14" and 16" MacBook Pro seem to have very nice displays

oh yeah my surface pro 8 came in yesterday

edid profile claims 100% coverage of srgb

measured it and it was 98%

but what I found confusing is that they include 2 profiles, 1 for srgb and one for "vivid"

I dislike how they almost encourage people to use inaccurate colours

i'm guessing "vivid" = interpreting srgb colors as p3 or something?

I think it's just srgb as displays gamut

macbooks have had p3 displays for a while but afaik macos has actually good color management so srgb stuff still looks correct

compared to say, Samsung who labels srgb as "natural". I think more people who don't know about colours would pick natural over vivid compared to srgb over vivid.

yeah colour management on windows 11 is broken right now so it's funny there's even an option

the current way to fix it (on release 22000) is to set the system wide default color profile

honestly most people (if they even found the page in settings) would try both and choose the one they think looks better, which would quite possibly be vivid, even if it's wrong

yeah, from what I understand, color management on macOS is done by the system itself by default

apps tell the OS what colorspace their content is in, and the system does the appropriate conversions

apps can opt out by saying that their content is in “DeviceRGB” and requires no further conversion

I have ordered one of the new macbooks models, I’ll try to report back (it should arrive in ~ a month)

a new version of DaVinci Resolve just came out with support for outputting in HDR on them: https://www.blackmagicdesign.com/media/release/20211022-01#:~:text=HDR%20viewers%20are%20also%20supported%20on%20the%20new%20Apple%20MacBook%20HDR%C2%A0displays

which is promising

Windows is the same in HDR mode, in SDR mode it's left up to individual apps

well windows hdr is kind of a mess afaik <:kekw:808717074305122316>

I was aware that Windows does some HDR compositing of SDR apps, but I didn’t realize that those SDR apps could also report their colorspace, is that new?

my experience of trying out HDR on Windows is that everything looked wrong

and I really mean everything

SDR or HDR

But notch is too big. They could have reduce it to 1/3rd

The hardware's not much better, my monitor is "HDR" but enabling it is barely brighter than SDR mode and it locks out/disables half the features

well that's not reallly a windows problem but a vesa problem <:kekw:808717074305122316>

In SDR mode whatever pixel values they write get given as-is to the monitor, to handle it they need to find what monitor they're on, the profile for that one and then handle all the conversions themselves

displayhdr 400 shouldn't exist

except for oled but there's a completely separate standard for oled panels

In HDR mode the monitor is assumed to handle Rec.2020 and Windows handles the colour space conversion from sRGB to that (Technically I think it uses whatever is set as the default profile, so you can change it to something like P3 and over-saturate SDR apps) when compositing

Apps that are aware of HDR mode can then tag their windows as being in a specific colourspace, like scRGB or HDR10 + Rec.2020

correct me if i'm wrong but iirc the display hdr 400 standard doesn't even require an 8 bit panel? afaik 6 bit + frc is still allowed on 400

that part, I was aware of (I wrote the comparison tool and its color management in libjxl)

this part I was missing, thanks! I wasn’t aware that it used the “default” profile for that

so basically, for a non-HDR-aware app to be rendered properly in HDR mode, it paradoxically must not do color management

otherwise it will convert to the display profile and the output will likely be interpreted as sRGB instead of the display’s SDR color profile

is that right?

whereas it would have been better off just outputting to sRGB and letting Windows do its thing

i hate hdr

I like it in principle, but the current implementations have a lot of shortcomings, yeah

https://crbug.com/1216691 😦

lol

from what I am reading online, macOS now seems to handle HDR very well: https://liftgammagain.com/forum/index.php?threads/apple-pro-display-xdr-for-color-grading.12846/page-13#:~:text=searing%20and%20horrific.-,Seeing%20a%20desktop%20HDR%20display%20with%20SDR%20and%20HDR%20content%20composited%20side%20by%20side%20was%20extremely%20satisfying.,-Alex%20Fry%2C%20Dec

but you need the pro display xdr specifically lol

Yep, I think mine is HDR400 and it only has 6 bit + frc

or one of the new macbooks

oh ye

Sorry 😉

afaik those links only work in chrome lol

<https://liftgammagain.com/forum/index.php?threads/apple-pro-display-xdr-for-color-grading.12846/page-13> unfucked link *but it doesn't link directly to the content in question*

it was just a link to this specific sentence: > Seeing a desktop HDR display with SDR and HDR content composited side by side was extremely satisfying.

oh that forum has their own way to link to specific posts

yes but the post is long, it wouldn’t have been enough

I wanted that sentence specifically

well it doesn't work in firefox lol

<https://liftgammagain.com/forum/index.php?threads/apple-pro-display-xdr-for-color-grading.12846/page-13#post-138213>

unless there's a special setting i need to enable

well hdr still looks like such a fucking mess so i think i'll steer way clear from using it on a pc and only use it on a tv 🤷‍♂️

if you like, you can use our new tonemapping tools https://github.com/libjxl/libjxl/tree/main/tools/hdr to convert to an SDR display of known brightness to get some sort of “pseudo-HDR” 😁

(slight improvement coming on Monday)

pseudo hdr <:monkaMega:809252622900789269>

can it do the opposite and map p3 back to sdr lol i admit i've never really looked much into photo stuff

because i've got a lot of p3 pics and screenshots that look absolutely awful on discord because no tonemapping lmao

maybe that was the wrong term — to be clear, it starts from HDR content, and renders it for an SDR display

ah

so that's the kind of thing i want lol

or alternatively i could just send it as jxl and not worry about discord fucking up the display of the image or stripping the icc profile lmao

Ok, Windows lets you set separate colour profiles for a SDR display and for SDR apps on a HDR display

ooh, cool

thanks

In Firefox, if I have HDR disabled it sees sRGB, if I have it enabled then it uses P3

You have to check a box when adding it, doesn't explain it well

so, it seems that all that is needed for system-wide color management on Windows is an HDR display, a way to actually calibrate Windows’ HDR mode, and to rewrite non-sRGB apps to use the new HDR APIs

I guess Apple had a headstart

> Apple developed the original 1.0 version of ColorSync as a Mac-only architecture, which made it into an operating system release in 1993. In the same year, Apple co-founded the International Color Consortium (ICC) to develop a cross-platform profile format which became part of ColorSync 2.0.

ok yeah, a significant headstart

It is somewhat surprising to me that software seems to be the bottleneck in making HDR display of images accessible to the masses

I somehow always assumed that affordable hardware would be the main problem, but once that was solved, they would ensure that things work properly from the start

Now the hardware is there, but software will probably need a couple more years to get ready to handle it

yeah, more and more people now have an HDR display in their pocket, but it’s a challenge to actually use its capabilities

We have hardware that can capture HDR, we have screens that can display HDR, but we have operating systems stuck in the 1990s.

well we also have companies trying to sell barely sdr displays as hdr

Yes, that too

It's just like the HD thing, where suddenly 720p was also a kind of HD, just not "Full" HD

Marketing people will do their thing, I suppose

which, if we could properly exploit them, would still be an improvement, I think

It doesn't help that basically OLED is considered HDR regardless of the nits it can do, just by virtue of its high contrast / nice darks

Also peak nits could be achievable with just a few pixels for just a few frames, and the actual full screen max nits could be very substantially lower

infinite dynamic range...

hdr is an abused term

youtube doesn't even consider 720p as hd anymore lmao

I think the term for 720p screens was “HD Ready”

Yes. Which was kind of misleading...

https://youtu.be/k3lvFuXo1IU

i mean i would consider 720p as basic hd but fuck 720p tvs lmao

you really want 1080p minimum now on a laptop or pc let alone a fucking tv <:kekw:808717074305122316>

Isn't 1280x720 the definition of HD?

... and 2560x1440 is quad HD (QHD)

afaik yes

but on a tv you want 1080p minimum

and you can't really find 1440p tvs

1280x720 is HD

but subjectively, is it high definition?

well compared to 4:3 480p yes

Depends on how far you are away/how big the screen is.

on a phone like the galaxy s3 720p isn't horrible

yeah depends

iphone 576p retina

i think the iphone xr screen wasn't too horrible too?

lol

how big was the screen though?

iphone xr is 1792x828

iphone 5 640p at 4"

ah well it's 4 inches

but the term HD is used for TVs

326ppi

so same pixel density as the iphone 13 i think?

or at least it should be similar

retina by apple terms specifically refers to 200-350ppi afaik

nvm iphone 13 is 460ppi

wayyyy higher

a problem with lower resolution is you get less space for actual things

or 476ppi on the mini

like you wont notice details but you will notice a dot

well that wasn't really a problem in the iphone 5 days afaik

it's a big problem for ui designers lol

768p is completely unusable on windows 10 though

well the iphone 5 is like how old now? lmao

iphone se is from 2016 lol

like, 1366x768 feels extremely cramped now

because you have the taskbar, the window header, all the toolbars, etc

but it's a phone and ios is extremely locked down and has a shit ton of standards for design and shit lol

which have a minimum size

i literally just said that

i mean for a computer monitor

ah

yeah don't fucking use 720p or768p on a computer

it fucking sucks

TVs larger than 40" must be at least 4k

it's wild that they still sell 720p 32" "tv"s

i feel like the low res problem doesn't really apply to the iphones since they're pretty high pixel density 🤷‍♂️ also apple is extremely strict with design standards and shit lol

i mean u can already see the pixels on a 1080p 24 incher lmao

i read a lot of text on my phone and i would definitely notice if it were lower dpi

on a phone lower resolution with high ppi isn't a big problem imo cuz hiding ui elements is a pretty common tactic

i think 1080p at 24" is fine, just on the line, i dont have a problem with it at 1.5 feet away, right next to a 1440p 27"

yeah it's fine at normal viewing distances

but if i lean in to grab something off my desk or to look at something closer it's extremely noticeable

do they even make sub 4k tvs at those sizes lmao

unless you're buying really old

like a plasma or crt

there's a 55" 1080p in the living room

but if you're buying a 40 inch crt you must really hate your back

well how old is it 🤔

at max 6 years

and hows the other specs of the panel

not great

kek

it's an lg though

weird

what model?

dont know

is it an oled or smth?

nope, i think it's an ips, lg and all

hmm

but it's not a great screen in general?

number of local dimming zones?

or just global dimming

i think it was before the time of when people heard of the words dimming zones

lol

well u said max 6 years

ok maybe 8

well luckily i don't think u can get anything that is sub 4k >40" made in the past year or so

well at least from reputable japanese, korean, american or heck chinese brands lmao

maybe you might be able to get them still if you just browse for tvs on aliexpress lmao <@!288069412857315328>

what im finding troubling right now is that retailers are selling old tvs

i cant find the years of these models

but they're being sold as new

ah

yeah

that's also a big problem i'd imagine

really old tvs being sold as new

hmm not even that old

2018

hmm

model?

haha im just looking on bestbuy

there's lots

oh no

at least the 40 inch crts are 1080i lol

lol it doesn't have hdmi only dvi

i think some of the later sony trinitrons shipped with dvb tuners and hdmi lmao

i am interested in getting a tv for my room

but it seems the price is still tied to the size

yeah

makes a lot of sense

larger panel = larger cost to manufacture

oh lol first results on bestbuy are 1080p 40 inch tcl and samsung units <@!288069412857315328>

2019 for the samsung

lol

bruh literally all of them are 1080p 40 inchers

wtf

and i imagine people are buying those otherwise they wouldnt be selling them

there's only 7 results and all of them are 40 inch 1080p

wtffffffffff

wayyy more results if you search for 40" instead of 40 inch

oh nvm the tv results are the same lmao

if you increase the search term to 45 inch instead u get non trash results lmao <@!288069412857315328> second result is a 4k samsung 43 incher

3rd result is a 4k sony 43 incher

the only 1080p ones i've seen are walmart brand and toshiba lol

even the chinese ones are 4k lol

Oh no https://www.instagram.com/p/CVaXgE2gGXj/

😐

needs EBCDIC-UTF

jokes aside iirc mainframe stuff have been using UTF-16 for actual unicode stuff for years. they just aint updating their stuff right

(just to be sure: EBCDIC-UTF or rather UTF-EBCDIC *does* exist, the joke is only the suggestion to use that)

yeh. its complicated thing no one actually seems to seriously use, where they do unicode on mainframes its usually utf16

So you'll need bandwidth instead of hard disk capacity?

Perhaps, although texture compression has also been improved, including hardware compression in the new consoles and also overall most likely not every player will need all parts of the game

I remember lolz can compress texture very well. (from free arc tool chain)

Haven't looked into this beyond the tweet, but usually "streaming" in this context means streaming from disk.

> By enabling this feature, the game will pull from the internet to provide more color detail on surfaces. Huh. Now I'm wondering if I had the wrong idea with other games.

They talked about being able to directly stream from the SSD for the new consoles, but I guess this is something different.

nah streaming for most games refers to streaming from the disk afaik only other games that comes to mind that use streaming in the context of downloading on the fly are the cloud game services and msfs2020 afaik

ban <@!288069412857315328> for crimes against humanity: using discord light theme

black text on a white background is better for reading

Why worry about reading if you won't have any eyes anymore?

it's mainly reading faster

and faster = shorter

Then you must have good pain control, because I certainly can't read while my eyes are burning in their sockets

i have my main monitor on 280 nits now since i got new bulbs

stop reading in the dark

I don't. Just don't want them to get cremated probably about 60 years too early

there's no strain if your environment is well lit

i used to go dark theme

in highschool

and with white background there's less contrast with my walls

I change my themes often. On summer and outdoors, I use light theme. on winter and rainy seasons i use dark.

my monitor is 120 cd/m² D65 during the day and 80 cd/m² 2700K in the evening

the warmer calibration at night helps with the strain

I use light mode in most things, but in discord I find that there isn't enough contrast.

i forget i have the css set to black

2700k? 😮 isn't that too much yellowish

https://youtu.be/MhQYSH4UvHA

it perfectly matches the lamps in my bedroom

it takes a few moments to adapt when I switch in the evening, but after that it’s fine

I see

I just have 1 trick question: do you have lights on in your room?

Yes

I'm not a gaymer, so light in my room isn't monitor exclusive

I don't understand, why only men have been subjected to conscription in some country? Is this law really fair?🤔

no. its probably more practical though

because men cant make babies

nature is totally not gender neutral

More relevant today, men are better adapted to the physical demands of combat. But today's militaries have a lot of infrastructure that isn't physical combat.

in war times a large reason was because of population

but yeah because of natural physical abilities, men are cheaper and also more disposable

what does aficionado mean? <:Thonk:805904896879493180>

>a person who is very knowledgeable and enthusiastic about an activity, subject, or pastime. o. i learned something new today

well, some trans men can, but conscription is usually by biological sex and not gender (and some militaries just exclude all trans people)

i always refer to sex

that wasn't likely to be misinterpreted

should i say male instead?

it's only english and in the west that has this stupid issue of male =/= man due to pc culture

no? trans people exist in non-western societies. i'm not sure how languages other than english deal with them.

i'd say male or amab (assigned male at birth)

yeah they exist but the identification thing/language has only been transformed in the anglosphere

context indicates this was a conversation about sex

yeah people with eggs vs people with no eggs

amab honestly sounds too forced and i doubt anyone out of pc circles would use it. anyways, wouldn't trans people be excluded from forced conscription stuff regardless of their gender?

depends on the military

iirc the US military says all males must sign up, but for a while trans people couldn't join, so trans women were in a catch-22

amab reminds me of the whole superstraight thing

Yes, that make sense, but if women don't make babies, they don't have to jail, but if men don't accept conscription, they have to jail, I guess this difference is very strange?

Nothing about war is fair or reasonable, imo

Where heavy physical and psychological exertion is required there is mainly a difference in physiology, the same for example in sports, so competitions are divided (also this is noticeable where there is no heavy physical exertion, e.g. cybersport or chess, although there are exceptions) And yes, babies, that's why in most countries many dangerous jobs are also not allowed for women

Part of it is also just cultural factors like macho traditions or sexism.

conscription is sexism to men?

To both men and women, tbh

It's discrimination to send men to die

It's also discrimination not to let women do that

Anyway, war is one of the weirdest human behaviors. It is very unproductive. It is destructive by definition. There are only losers - except I guess the shareholders of the weapons industry...

About difference in physiology, part women physiology is weak than men(no sexism mean), so law protect women, part men physiology is strong than women, so law force men to do something, and don't have reward, This difference also very strange? I think law implemented can't depend gender or physiology state?

That's a weird way to put it, given conscription is not voluntary. Volunteering for service is a totally different thing.

Point is there is a discrimination (a distinction being made) based on sex.

Conscription is probably generally seen as forced service that nobody really wants to do, but I suppose there would also be people who had a positive experience, saw it as an opportunity to make friends and bring structure in their lives or whatever

I've known people who've had a positive outlook on their required service, both men and women. I just suggest "not letting women be lawfully required to serve" is awkward to pose as an injustice to women.

the bigger injustice is requiring anyone to be involved in war

<a:Military:821038589571235850>

I am also ex-military, both conscription and contract I think conscription still exists because every country needs a certain number of military or at least trained population for military conditions and this cannot always be provided only by voluntary service, like there is not enough funds and propaganda to make this service attractive And while there is no way to eliminate the war among mankind or to unite all the countries into a single whole, the countries without sufficient army can be put under different political pressure or demands of some unfavorable conditions for protection by forces of other countries

Every country needs a certain number of military, Agree, this point is make sense, but about conscription and men, In gender equality, I think government need provide more reward or benefit for accept conscription men, to preserve equality. (like most country have some law to protect women physiology issue)

Men can get some benefits/awards in most countries, though mostly in jobs close to military service, like police, forces, etc. And about jail, in some countries women can also be jailed or punished because of their physiological differences, e.g. for abortions

In my country, conscription salary only have 185.02 EUR / 1 month...😢

I wonder why big tech companies have the tendency to end up with a name that is extremely generic or unrelated to what they actually do

Meta, Alphabet, Apple

Apple doesn't sell apples

Amazon has nothing at all to do with the river

<@!794205442175402004> Do you have better names to offer? ^^

Google and Facebook are OK names: they are somewhat related to the main thing they do, and they are kind of unique words

Alphabet and Meta are stupid names imo, not at all unique or related to what they actually do

well the distinction between alphabet and google is only really relevant for financial/legal stuff. google is still generally known as google. unclear if that will apply to facebook/meta (initial rumors i saw talking about the name change said the social network would still be called facebook, but i'm not really sure).

They would be stupid to throw away a super recognized brand name like that

(also likely even if they do, people will keep calling it facebook)

Alphabet gets it's name because they are supposed to make things important for humanity like the alphabet

(imo alphabet is a weird choice though)

To me such names sound like Hubris

indeed.

When companies go Meta, even their names are like an Alphabet pictograph. Like a for apple, b for..

Exactly

What do those names have to do with what those companies do?

Alibaba apparently means "to find treasure" which makes sense if so, but the others I have no idea how they relate to what they do <:Thonk:805904896879493180>

Well, TenCent is quite obvious. And it's one fifth of a rapper.

> The name Baidu (百度) literally means "a hundred times", or alternatively, "countless times". It is a quote from the last line of Xin Qiji's (辛弃疾) classical poem "Green Jade Table in The Lantern Festival" (青玉案·元夕) saying: "Having searched hundreds of times in the crowd [..]"

> Chinese characters Teng and Xun which means something like 'galloping fast information,' https://www.wbur.org/onpoint/2014/03/25/where-alibaba-and-tencent-got-their-names

Have something cursed: an image Bandcamp uses... static gif

78.7KB, converting it to PNG even makes it smaller...

57KB with fast conversion <:KekDog:884736660376535040>

~~56.9KB with slow conversion by yeeting it through many optimizers and see which one gives the best result~~

Interestingly jxl doesn't get any smaller on this image. With `-d 0 -e 9` I get 63.2 kB.

When converting the gif directly I can get this:

Hm, seems like png beats jxl in this case

I do get slightly different results converting from the PNG to the GIF, but not to the degree you got. What are you doing different?

Using different parameters

Used ``cjxl -e 9 -q 100 -I 1 -E 3 -g 3 ``

Ah, yep. That gives me 60548 bytes as well.

~~Gotta get every jxl version and try them all <:KekDog:884736660376535040>~~

What do -I and -E do?

Ah found them in the help.

"It's the fraction of samples it looks at for doing MA tree training"

No idea what -E does tbh

``` -E K, --extra-properties=K [modular encoding] number of extra MA tree properties to use ```

it won't do anything in the palette image case

it's the number of previous channels that can be used to determine the context

i.e. -E 1 means the MA tree can contain `Prev` (and `PrevAbs`, `PrevErr`, `PrevAbsErr`)

-E 2 means it can also contain `PPrev`

and so on

values larger than 3 are not useful unless you have more than 4 channels somehow

Wonder if there are any other parameters that make a positive difference for lossless other than ``e``, ``I``, ``E`` and ``g``

Sometimes X and Y can help, or palette

Also `-I 0 -P 0` can be better sometimes

Hm

No idea what X and Y are, but guess I'll try -I 0 and -P 0 sometimes

``-d 0 -e 9 -I 1 -g 3 -P 0 -X 0 --patches=0`` maybe better settings but that is what i found

Nice

Wonder what -P 0, -X 0 and --patches=0 do

-P 0 forces the predictor to zero (MA tree has only `Set` leaves)

-X 0 disables global channel palette (in general, -X n means "make a global channel palette for a channel that uses less than n% of the values in the range between min and max")

--patches 0 disables patch detection (patches are usually a good idea but they can be counterproductive)

Hm, guess I'll experiment with that stuff then

Gotta get the best possible efficiency for lossless <:KekDog:884736660376535040>

continuing a discussion from <#822105409312653333>: is there an error correcting code designed for a very low bit error rate (say, <10^-5)?

that is, just about enough for detecting typical bit rots

with par2, the level of redundancy is customizable, but not sure how low it goes

the ANS final state check is very likely to _detect_ errors

_correcting_ errors is something else and seems hard to do without introducing a large compression penalty

So my line of thought was that we only need to guard against a low probability bit flip (we don't concern burst errors), which limits the bit error rate very low and it might be possible to put a low effort ECC for catching most such bit rots

I'm not good at coding theory and all I can come up with is a very large Hamming code, which requires log(n) space overhead and n log(n) time overhead I think
