JPEG XL

Yes, the mpv

It is good the media player

All 3 names are used for Joshua, the guy after Mosheh.

Open source and with on the ffmpeg

ahh yea, I have that. it works for it.

The J is a Y sound

Joshua is friend from my old school?

No wait is that Joseph

It would be the Hebrew letter Yud

Yes it maybe

Joseph is Yosef

J is variation of the I, which helps in the Latin like Nikuds helps in the Hebrew to know if the Jod is used as a consonant or a vocal.

So Iehovah, became spelled Jehovah.

and so forth.

and the I goes back to the Greek Iota which goes back to the Hebrew Jod

Iota in Greek looks like an I.

anyway....

Josayf as far as I recall, you have a Tzayray in it.

Like Jay-shu-a - not like Je-ho-vah on the first red letter pronouncing.

I know a bunch of Hebrew-speaking Jews

Jayshua have a Tzayray, Jehovah have a Sheva.

Sure sure. Use the name Jehovah in front of them 😉

I heard people stopped speaking Hebrew for thousands of years and Aramaic became one of the biggest languages on the planet

Naaa Hebrew have always been spoken - it never died out. But of cause now you have a lot speaking it - but it was never forgotten or totally dead.

People spoke Aramaic for a really long time, in many parts of the world. It's shocking that a language can last for such a long time

Like what tongue is the Bible written in? Hebrew, and you always had people being able to read the scriptures.

Now that I rewatched the video I'll say it doesnt look like av2 at all

You have a little Aramaic in the Bible - but it is not that much. But like Dani'ayl have some.

I heard at one point people forgot how to read the Hebrew, and they translated it into Aramaic - the Targum Onkelos translation

But I could be wrong.

Naaaa, it never died, you always have had people knowing Hebrew.

When is av2

Though on motion affine is good Better than the Intra blocks not the gamma

I have a 25042025 build

But yea, you do have those Targums as well for explaining things. Kinda like....... somewhat commentaries.

They need to fix 25 bugs of the same thing

That is. Lot of builds

If you're catholic the current version of av2 is illegal to try

Most scholars call that diety Yahweh, but regardless of how it's pronounced, his followers seem to believe they are forbidden from saying his name.

Av2 Born dirty

I am clearly not a Roman Papist 😉

Meant to reply to this lol

Yea, they are wrong on that. Both Papist and Jews don't want us to know or use the name.

It is Jehovah.

as you are the Jewish?

Ah

I can recall 20 Jewish sources on top of my mind, although I can quote them all.

Spiritual Jew, not a Jew of the Flesh.

Do the Jews support AVIF?

Cloudinary is Israeli right? 😂

I am sort of opposite I do not religion but one of my parent is Jewish

Ginsberg verified Jehovah, Kalker verified Jehovah, 16 Jewish sources from Nechemjah the Scholar, Tovia used it many years ago and I saw a Jew using it on a video on the internet twice - and of cause talking to Jews in Israel as it goes - they never forgot.

I love Jews but I don't really like religion all that much.

Father or Mother?

Father I think but Only 1 of them

Out of 4

You have 4 dads?

you only have one father of the flesh.

I don't follow any religion other than potentially theistic evolution but I do not discrimiate the people

Damn I feel inadequate now

Anyway, if you came out of the loins of a Jewish Father of the flesh, you are Jewish.

It's passed down from the Mother actually.

My father is Jewish but he is not made of my flesh

no, that is false tradition of the Jews - we go by the Bible.

If you watch Fiddler on the Roof you'll know Judaism = Tradition! 😂

Kinda messed up that the Jews ended up with that tradition, Biblically the tribe goes through the Man.

libjxl should add support Judaism

Search av2 mscnn pdf

Biblically and traditionally I don't think God cares 😂

I love God, not religion

As far as I recall that tradition goes back to..... Sabaterians or something of that nature, little dry on the that topic.

For real av2 was born by atheist

does god pay his taxes

Well everybody needs Jesus for salvation, and not the cookie Jesus of the Roman Papist.

I do not know

That's what the Romans asked Jesus 😂

I do not believe in anything

Well, Jesus did get Peter to get that coin from the Fish to not offend them and pay whatever they wanted.

Only in Trump

Give to caesar what is caesars and give God what is Gods.

Jesus was not made in America so has to pay a tariff!

Actually, everyone already has exactly what they need.

Do not talk about flesh here

Not according to the teaching and doctrine of Christ.

Anyway av2 mscnn pdf is bad

It was made on easter day

Jesus said He was the ONLY way to everlasting life.

🍖🍖🍖

So it wqs made to do god mad

Easter is a pagan tradition with all sorts of rubbish like egg laying rabbits or hares.

Av2 makes god mad

What is AV2.

They are fixing 25 bugs to publish it

But not removing the av2 mscnn pdf document

.....

Yeah, I kinda doubt it... Jesus's message was coopted by the Roman state and turned into a completely pagan political tool of control.

I don't think Jesus ever said that you don't have everything you need

Krisna Rapaka dis for money

Well, Divinity, Death and Ressurection - the Gospel of Christ dying for sinners.

Me also hahaha

AV2 leaked source code: ```cpp #import "satan.h" int main() { satan::encode_image(); } ```

The worst that i'm considered a ped

Not actually

This whole "Jesus as some kind of bouncer standing between you and God" never made any sense

Jesus is God.

Av2 leaked source code

Elohim in Hebrew is Plural word for God.

Elohim said let US make man in OUR image in OUR likeness.

Father, Son and Their Spirit of Truth was their from the very beginning.

Can stop talking about av2

Is seeuoys in every moral way

From the beginning

Just like me

God is "I am"

If you do not believe that I AM, you shall die in your sins. - Jesus

That's probably why you're not supposed to say his name. So you don't realize who he is 😂

Jesus was, is and is to come again, Jehovah.

He who exist.

I'm a sinner

I don't believe in waiting for a savior 😂 I already have exactly what I need, and everything I ever asked for.

I'll die in the hell with Krisna

God died for sinners on the tree, on the Cross where his Living Bread from the Heavens was broken, the Pass-over Lamb of Jehovah whose blood was spilled for sinners.

People who are waiting for a savior will get one too, and it won't be pretty

His Wine poured out for our sins, if we would turn around and look to him who was lifted up.

They will either kill him again, like they always do, or they will get the most evil mass murderer the world has ever known 😂

Well, Christ is coming back of cause to put an end to the Roman Beast 666.

That's why I don't believe in asking for a savior

It's the wrong thing to ask for

Just ask for the strength to do the right thing

The Pope 666 will be obliterated and done away with.

Or the left thing. Whatever floats you boat

Without Jesus we get a ticket to the lake of fire and the second death where both body and soul will perish eternally.

So in other words religion is for people who let themselves be guided by what they are afraid of instead of by what they love.

In my music i Only teach about sins

I compose music for trans people

Love and Fear can go hand in hand. Both can be good and useful if it is the correct things you love and fear.

Let your life be ruled by what you love and admire, not by what you fear.

Fear jumping out from the top of a skyscraber is a good thing and can keep you alive.

Not all fear are bad 😛

If you let fear be your guide, you'll find lots of things to be afraid of

If you did not fear anything you could quickly end up death.

You don't wanna jump out from skyskrabers, trust me!

Doing ai portraits of a 10yr old child isn't normal

Natural law will take over and you splat on the ground.

Yes it's true but in order to make rational and good decisions we need to be in a relaxed and safe mental state.

AOMedia shouldn't justify their atheism in that way

You have to have a lot of faith being an Atheist.

Bydeengo choi did a huge mistake on 2021

Why that thing supported by an university

Someone said, I have not enough faith to be an Atheist.

It really takes some faith to be one.

I don't have any faith, I have knowledge. And I'm not an atheist.

Cause and Effect.

As it goes.

Why byeendochoi doesnt remove the link

Or the inappropriate image

If you're in a relaxed mental state and you feel safe, you can balance just fine even on the edge of a precipice. But if you are afraid of falling off and terrified of dying, you will lose your balance!

So what kind of command do you use for the avifdec or avifenc

And if you jump out of a building from up high, you probably won't live long.

So keep you fear strong and don't do such a thing.

I'm sorry to get you too mad

Not much info: Added since 1.2.0 Add support for outputting all frames of an image sequence in avifdec. avifdec --index all sequence.avif out.png creates files named out-xxxxxxxxxx.png where xxxxxxxxxx are the zero-padded frame indices.

Worrying about the afterlife and whether you'll go to hell for being in the wrong religion or whatever, betrays an ignorance of God. Do you think someone like That, would really care about something so trivial?

Lake of fire, Hell is a bad word to use.

It's a lie designed to disrupt the rational, logical process in your brain

A Program needs a Programmer to Program it. We have the Program, the question his who Programmed it, who is the Programmer.

The cause for the effect, science.

DNA is a very advance code, a program, full of information - that just don't come around by itself.

Like I said, if you stay in a state of safety and calmness, you make much better decisions. It becomes easy not to trip and fall. But if you're afraid you will definitely lose your balance and slip.

I'll cling to Jesus 🙂

Beware anyone that tries to use fear to pressure you into making a decision. It's a classic tactic of scam artists

Jesus is Savior, so.... that is the one we need to cling to until we die the first death.

It hasn't the full reasoning a religious have

You can call Him that. You aren't going to be judged for what name you like to call Him. Not unless YOU judge everyone else for that.

Anyway i segnaled that

Jayshua would be more correct.

"Judge not, lest you be judged by the same metric."

but most people know him by the name Jesus.

Hope Google would fix it

If you don't have Jesus, you don't have life. Without him we die the second death.

So.... that is the 2 options presented to us, pretty much. The narrow way of Christ or the broad way of the Devil.

Few ever find it.

Try this one about Jayshua: https://jesusgod-pope666.info/uvpf.php#/?playlistId=1&videoId=4

It is the very best! 🙂

And use whatever you want on the page.... everything is free.

I am thinking of making all the videos into AV1

should save some space.

Which would be nice.

But I probably need a faster computer for all the encoding.

Just the images takes hours and hours on these terrible computers.

I also have..... https://aM.JesusGod-Pope666.info - some of them have subtitles working 🙂

I made some subtitles by AI help, transcribing and translating.

How to recompress dngs using jxl? I think I have a real dng.

But that also requeres a lot of computer power.

avifenc -q 75 input.[jpg|png|y4m] output.avif avifdec output.avif decoded.png See avifenc --help for all options. I found something.

He even said, his "followers" will come to him "on that day," claiming to have done so many great works in his name... and he will tell them, "I never knew you. Begone!"

He knew his teachings would be lost.

Yea.... There would be Wheat and Tares growing up together, since the first century until the Harvest in the future.

He knew "few will ever find the door"

No, his teaching was not lost, you just have the Children of the Devil playing Christians, who are fakes.

All those Roman Papist being part of Mystery Babylon - are worshippers of the Devil.

Wolves in Sheep clothing.

They worship a Cookie Jesus, and pray to the Satanic Queen of the Heavens who they call Mary - and they follow the Antichrist who is known by many as the Pope.

All Protestants in the past knew full well that the Papacy was the office of Antichrist 666.

But the Devil has been effective and now most people are utter ignorant.

The sun-worshipping Romans co-opted Christianity for themselves, and took it upon themselves to define what Christianity is allowed to be.

and the Devil keep people occupied with all sorts of fun stuff....

Christ and Christ alone!

It was turned into a Roman cult

and to the fire with the Poop.

Some places in England they still burn the Poop in effigy each year.

I don't think it's good to cheer someone's death but I'm no fan of the Pope either.

Well, it would keep the knowlegde of Antichrist going, as people would think, why are we burning the pope on the fire in effigy?

well because he is that Antichrist 666.

It is known as Popes day or guy fawks day.

guys if you're going to talk about religion please don't do it in <#794206087879852106>

When the Papist tried to blow up the Protestants parlement with the King so they could take over England again. A Jesuit conspiracy and plan that failed.

can you please move to <#806898911091753051>

You are right, we ended somewhat off topic here.

what's it currently encoded with?

if you use the CLI tool `dng_converter` there's a `-losslessJXL -jxl_effort 9` commandline switch

But I did get the AVIF sorted of that compiled file. Just need to figure out some commands for it.

I think it's raw. Not demosaiced.

Where is that tool? In libjxl?

it's in the DNG sdk iirc

<@238552565619359744> has done some work with the DNG stuff and may know a bit more

You should be able to use libsvtav1 aka svt-av1, it only support 420 subsampling, but your videos are likely already 420. it is very fast

https://github.com/dnglab/dnglab/issues/528 Hmmm

what is bit depth of exported image

8

10

and 12

oh from 8-12

okay I got it.

16.000.000 colors would be more then enough.

It's actually not that surprising, JPEG was considered bleeding edge technology in 1992. Of course it pails in comparison to AVIF which was created in 2018 and was specifically tuned for small files and low bit-rates.

do you think jxl with some low bpp optimizations could catch up with avif?

Of course, they share a lot of the same technology and I think it's just a matter of tuning for appeal rather than fidelity.

It may sound blasphemous but I think trying to preserve detail at such a low bit rate doesn't really make sense.

AVIF learned a lot from JPEG XL's techniques, maybe it's time for the vice versa. 😅

It's not *massively* far off, considering there's been no tuning whatsoever for anything above distance 3 or so https://discord.com/channels/794206087879852103/794206087879852106/1368117359797080085

its different enough to be noticeable i think

dng_converter is an Adobe tool that I've spent at least a full day of my life just trying to get working whenever I try to use it. Order dependant, case sensitive, no-printout commands... Awful to work with, but it does support Bayer and Linear encoding https://helpx.adobe.com/uk/camera-raw/using/adobe-dng-converter.html

If you want to keep your sanity, this works fine too https://tinydng.com/

It has a lossless and CLI option

thanks. does the tinydng has jxl (re)compression?

You mean taking JXL DNG input?

Or just encoding to JXL, because yes

compressing dng bayer data with jxl algorithm

Yeah, it has an FAQ, it keeps the original format

Sorry I read everything on that page except that part

They do put the most important info right at the bottom haha

I mean, I did try resampling 4 for the *very* low quality range, a tad too blurry xD

Well, awesome for my pictures as far as I can see. Like I will be able to make them so small and yet have a bunch of photos on the web host - this is awesome.

And there seem to be room for some further tuning. I need to figure out how to try that Terminal command thing you gave me, or someone gave me.

But overall, probably not much of a difference really whether I use one or the other.

I have the Gimp 3 AVIF and the XnConvert and the Terminal app as well that I need to figure out.

Overall it does take a lot of time making the files but..... it will go as it goes. They can do there thing while I sleep.

Anyone knows the code for the Terminal app for encoding a folder? Maybe it is just like the other app and coding.

also my file manager in Linux now portrays AVIF files thumbs 🙂

I installed all of the AVIF files from the installation thing, and after restart something worked and now showing thumbs for AVIF files.

in the file manager.

so that is very nice.

whatever did it.....

My Crapbar working on it 😛

Although not sure if the settings is.... If the image profile is really not hit much, I could go with one of the 2 others and lose some more fat on the files slimming them even more.

But.... whatever, I guess we can just go from there and I'll fix data on the folders, and can then further replace things afterwards if I find something better and let the old machines work while sleeping over some weeks.

or months.

But look at those slimming numbers :S absolutely amazing.

I just use `avifenc -s 4 -d 10 -a tune=iq input.png output.avif`

are you okay? I understand being upset at the slow adoption of new tech, but this is a very pessimistic perspective on this topic new tech adoption is usually really slow, arguably adoption of av1 has been fairly quicker than adoption of vp9, opus is offered on many music services, and data compression can be applied by any person as they want (as long as you can easily decompress it)

what a primitive opinion. Why should they be adoption at all? why? because it's new? just because it's new? there is no reason to adoption them, at all. the costs are incomparable with the benefits, and without any guarantees of compatibility

do you know why no one supports vvc? because everyone is sick of these technologies, and not because it is patented, everything has already been strangled to hell, so that everything needs to be updated again, again monitored for 3 codecs at the same time, keep copies of all of them because of the lack of compatibility. they are sick of writing a new hardware decoder for their chips every couple of years, which of course will not work on these $50 smartphones, on which even av1 laggs in 720p with hardware decoding and the encoding speed at which it becomes more efficient than the previous codec is so high that neither ordinary users nor owners of sites and services want to do it. Why spend 10 times more time on encoding if vp9 -good -cpu5 do brrrrrrr

as I wrote, in the settings there is a native function to completely disable AV1 on YouTube

in fact i haven't seen any global works in jpeg xl for several years. are there really 5 people working there?

maybe I don't follow the news well. no innovations, no global things, no promotion, implementation, maybe even advertising. Outside this server, you don't hear about Jpeg Xl more than about VVC (that is, nothing)

funny. I knew that, unlike twitch, youtube converts your stream completely. But I forgot. It's funny. In this case, it's not clear at all how it should work. In theory, you can just stream 1440p even in AVC format and youtube will do it in VP9

YT would be crippled if they did that lmao

I wonder if there are any good asics out there yet for large scale

Last time I tested, around 6 months ago, this was the case. Maybe it changed in the meantime, I'll maybe have a look at it

VP9 is for 1440p+ regardless of input, avc for below

av1 is far to slow to do live

slow to compress on the live?

Anyway to use a mobile for batching of image files?

Like maybe one could use....

Termux to install one of these codecs and do it.

Termux has libjxl

So it also have something for AVIF I would think

So I can run these in Termux?

Would be nice to just be able to fix a mobile to do the job and then have it run in the background for however long it would take.

With chroot you can run gui with vnc

On termux

thumbnails working, although not sure what I installed to get it working, pretty much just installed everything I could find in the installer with AVIF

but something worked after a restart.

Can you explain the detals here.

avifenc is the app

-s ?

-d 10 Speed?

tune=iq ?

input of cause and output I get those.

I wonder if I could then put the avifenc into Termux somehow and get it working on my mobile.

I am sure it would be faster encoding then my crapbars

or my crab computers.

And I have a couple of mobiles that could do things while doing other things.

Is the quality made better if it is slow compared to fast? or is it just compressing it more?

on AVIF

It's a command line interface. Typing in `avifenc -h` should explain the settings pretty well.

Yea, just some "human" interaction you know.

I have the h file up

So you're asking me why I chose those settings?

but never been good at those help files

-s: speed -d: bit depth (8 or 10) -a: anything after `-a` is passed to the encoder library directly (in this case, libaom) tune=iq: passed to libaom directly to specify the tune (in this case, iq) input.png: the input output.avif: the output

Ahh the bit death, yea I was listening to something of that yesterday on YT

trying to get my head around some of the things.

avifenc -s 0 -d 8 -a tune=iq input.png output.avif

0 is the slowest correct?

Oh so it is some kind of tuning made by someone.

input.png, can I make that into a folder and output made into another folder?

Like the other transcribing app I have as -i and -o I think it is for input and output and then the folder.

but I guess that might not be the same here.

while avif isn't going to be using RGB in this way, we can think about it like this: - RGB has 3 channels, and bit depth is specified as a value per-channel (usually "BPC") - 8 bits means 0 to 255 for each channel, while 10 bit is 0 to 1023 - With 3 channels, this means that we can have 16.7 million colors for 8-bit, and 1.07 billion for 10-bit full range RGB

it changes the encoder to be better for images

Yea, that is always nice of cause.

*always* use `-d 10`; there's no point in using 8-bit, even if your source is 8-bit

well -d 10 would make the image bigger....... as far as I understand?

I am making the photos for web

no, because image data isn't compressed in pixel space, it is all done in the transform domain

okay

more bit depth means more precision for the transforms to operate with

`find . -name "*.png" | parallel avifenc -j 1 -s 0 -d 10 -a tune=iq {} {.}.avif` i think

So 12 bit would not make the image bigger in any way?

10-bit is the sweet spot. "bigger" doesn't matter, it is the ratio of quality to size that matters

So what happens if I use 12 bit?

It's just inefficient, causes an increase in encode times and decode times for no tangible benefit

Aha, okay.

it is usually worse than 10-bit. it could probably be made to be better, but 10 bit is the best right now

but 10bit gives you some.... benefits

okay.

it is one of the easiest ways to get benefits. it is usually a 20+% improvement in metrics, and visually prevents banding

Also, I think speed 0 is wayyyyy too slow, this man is on old hardware and I think speed 4 is more than enough.

https://wiki.x266.mov/docs/introduction/video-artifacts#bandingcontouring

ah yeah makes sense then

so, like this? avifenc find . -name "*.png" | parallel avifenc -j 1 -s 0 -d 10 -a tune=iq {} {.}.avif

`find . -name "*.png" | parallel avifenc -j 1 -s 4 -d 10 -a tune=iq {} {.}.avif`

go into the folder you want, copy and paste this into the terminal, and you should be all set

Yea I am on crap hardware, but still..... 😛 Like if it can it in the background and get some more compression that is of cause nice.

parallel may not be a good idea?

eh id just do it

oh -j 1

yeah

does the slower speed help on image quality or just compression?

both

roger.

these are inherently linked, so both

Thanks, gotcha

but you do get diminishing returns, so I'd probably just stick with speed 4 to start

Yea it was fast with 10 speed for sure when I did it, seemed as fast as making JPEG files.

speed 8 is around as fast as mozjpeg iirc

whatever bit can be saved on the website is nice 🙂

generally the wisdom is don't go above speed 6 if possible

roger, thanks.

and thanks to you all of you of cause for all the information, it has been very helpful.

if you want even more helpful info, there's a wiki for codecs: https://wiki.x266.mov you can search for "AVIF" or the like and learn about them

avifenc find . -name "*.png" | parallel avifenc -j 1 -s 0 -d 10 -a tune=iq {} {.}.avif

don't add avifenc to the beginning

oh

avifenc will run after `parallel`

ahhh, I see

How does it parallel, make a folder at the side?

`parallel` just splits jobs between your cores so it can run faster

oh okay

if you have 12 images and 4 cores, parallel will process 4 images at a time

avifenc find?

Where is the quality setting in the line?

I see the speed and the bit option.

If it's not specified, it defaults to 60

I want 50

Then add `-q 50`

At least that seemed pretty good as well, 50.

great

``` % avifenc Syntax: avifenc [options] -q quality input.[jpg|jpeg|png|y4m] output.avif where quality is between 0 (worst quality) and 100 (lossless). Typical value is 60-80. Try -h for an exhaustive list of options. ```

find . -name "*.png" | parallel avifenc -j 1 -q 50 -s 0 -d 10 -a tune=iq {} {.}.avif

Yea, I don't think 50 was that bad as far as my results go.

and it sure makes the files small.

¯\_(ツ)_/¯

very small....

insanely small 😛

Deadset on speed 0 huh? It's going to take days to get through 40 GB worth of photos on old hardware

yeah tbh speed 6 may be fine there

I don't go lower than speed 1, speed 0 sometimes gave me images that looked worse psychovisually

Also it takes like a stupid amount of time

Yea I do actually come to remmeber I had something of that kind when compression video's many years ago, there was sort of a sweet spot.

But overall, if I get the settings I want and all, even if it takes a week to do, it is fine.

Like it can run in the background or something.

The issues are finding the right settings here at the moment.

Most likely a week 😉

I still would like a new computer, had my eyes set on one but I did not get it at the offer.

So I am kinda just waiting for..... something of that kind getting a little cheaper.

sick and tired of these slow devices for sure.

if you don't have a time constraint, it doesn't matter. I have written a script before where I started it from time to time (it could continue where it left off) which also did quality checking with ssimu2 and butter between encodes.

though I agree, practicality is another thing with s0

with diminishing returns

<@207980494892040194> I have tested it with videos before: I assume similar returns for images

But overall, taking into consideration of the data being move on the website.... in the long run will save you some space.

Is might thoughts.

anyway....

s0 is technically the best, that's for sure

again, if you don't care about time constraints, go ahead

yea, great. I'll go with that then.

Yea, like it can do things in the background when I find the right settings.

still testing.

and reading and trying to figure out things.

with avifenc, you don't have to test many things though (except quality value maybe) just make sure to encode in 10bit, 444, and with tune=iq

Like i am not totaly settled on the 444, 422 or 420 or RGB stuff.

you don't have to know anything detailed

444 is simply better, more quality, less size

okay 10 Bit.... 444 and with tune=iq, which I guess I can only run with this compiled encoder

ahhh okay, you sure 444 is not higher size, I thought I tested 444 422 and 420..... high to low but maybe I am remembering wrong.

``` avifenc -a tune=iq -d "10" -y "444" -s "0" -q "desired_quality" --ignore-xmp --ignore-exif --ignore-gain-map "your_reference_image" "output.avif" ```

we did many tests, belive me, 444 + 10bit is the way to go

Roger, but it does seem 422 and 420 makes smaller files, is what I am getting at.

The quality might be worse, but the size as far as my test in the pictures makes smaller files.

no

You can't test that with a single encode

You need to test whole usable quality range both with 420 and 444

420 is not even able to produce high quality images

as you can see it can't pass "52" `ssimulacra2` quality score.

okey but sure ssimulacra2 of cause would probably not be happy about the lag of color information or something. The question would be visible for the user.

with very low quality, yes, it's slightly more efficient but with `cjpegli` not `avifenc`

I don't know.

As I understood it and I might be wrong it was something with the colors that it did.

what about RBG setting?

Y = Brightness (how light or dark something is) U and V = Color details (like red-blue and green-purple stuff)

YUV444 (the fancy one): Every pixel gets its own brightness AND its own color. Super clear and colorful! Great for high-quality video or editing. But it takes more space (like a big file).

Yea, so is it not just color informations it is reacting to when it is testing the image for quality on 420 vs 444

but the last point shouldn't confuse you because the quality increases along with it

that's what we call efficiency

you can always reduce the `-q` level to make the sizes match

then 444 would be higher quality in the same size

aha, so what you are saying is a 422 or 420 equals lower Q setting compared to a 444 with the same Q.

Yes, that's why we make these graphs

So 444 and 10 in bit, okay....

you need to have many datapoints to compare. These graphs use all the quality values

RGB setting vs 444?

so we can compare the similar size encodes

rgb is not as important

you can add this option

Yea I am not the expect for sure, just collecting data inputs and trying to get a hang on things.

``` --cicp "1/13/1" ```

Well Gimp 3 has an option of RGB or 444

I am not sure about that, I am strictly talking about avifenc with its libaom backend

controlled from the CLI

okay, you mean the terminal compiled thing.

Just trying my options here and there 🙂

Never use RGB with AVIF it's horrible.

I didn't even know it supported RGB 😁

Lossless remember?

oh, right

It's so bad that even AV1 fanatics forget about it <:KekDog:805390049033191445>

I am desperately trying to be a JXL fanatic

Welcome to the club <:JXL:805850130203934781> <:FeelsReadingMan:808827102278451241>

though AVIF development makes huge leaps forward, interestingly

probably because they only care about the rate distortion

it's not an inherently image format, at the end

where JXL has many other uses/features

AV1's primary appeal is its rate distortion curve. So devs work round the clock to make sure it's up to snuff.

While JXL has very impressive compression, it's mainly the unique features that companies want

So that's why libjxl devs are focusing on a stable API and a rust implementation.

Chromium support is the key I assume

therefore Rust

?

you can ignore that, but this is simply giving color hints to the encoder

roger

yea it is as an option in Gimp 3

roger

I guess one of the great strength with AVIF is AV1 being supported and seemingly going to be the next big thing on video compression.

It's not the next, it's the current biggest thing in video compression 😁

It has been for a long time already

huge community, many forks/devs, enthusiast users, browser support, funding/adoption from huge companies

okay, gets to technical for me 😛

These were what 1/13/1 meant

Well, just ran into it not that long ago.

yea I gathered, although did not make much wiser 😛

I guess a setting you can put into the encoder

Yea clearly AV1 is doing very good - I might save 50% on my webpage if I encode it all into it.

but.... need a new computer for that I think.

that would pull the teeth out of my old crab devices.

But I might still do some testing I guess on it.

But first.... the images....
