"maximum size for this upload session" something something

[Thatusernamehasalreadybeentaken]

i was able to add half the pages of a chapter before i started to get warnings and then everything disappeared

Copied from upload chapter page

File requirements and limits:
An image can be at most (10000 x 10000) pixels.
The maximum size per image file is 20MB.
The only allowed image formats are JPEG, PNG, and GIF.
The maximum total size of your chapter may not exceed 200MB.

Maybe check if your pages/chapter aren't too big?

 

[Thatusernamehasalreadybeentaken]

no they are not. the pages are below 20 and 10000

The maximum total size of your chapter may not exceed 200MB.

and this sounds like utter lunacy. like, some chapters are 18 pages long, this chapter is 70 pages long, and let's assume a chapter that is 200 pages long. so all three cases have the same limit? you get 1mb per page in a 200 pages chapter, which is like 144p and overcompressed artefacted to death, in the age when everyone has 65" 4k screens. there's already a per-page limit, that's enough. and also it's meaningless because the servers accumulate all the pirated content they can, if i cut a chapter into 10 pages 20mb each chunks i upload as much data as i only want, it's just poorly split in the reader-faced interface into nonsensical chapters, when in fact all the pages are from the same paper chapter

btw the half of the pages went live and i can't upload the rest of the chapter

Your original page is 5.47mb. This page, which I spent thirty seconds optimising, is 979kb.

Spoiler: Image

It is not 144p and overcompressed/artifacted to death.
Level your scans and denoise them, otherwise you massively inflate file sizes for no gain.

The true chapter size limit is 300MB, the half-chapter you uploaded is 284MB, the average chapter on MangaDex is 13MB.

Also, page 1/22 are both over 20MB individually.

you bit-crushed it into eye-piercing windows 95 for blind theme. like no joking my eyes got tears in them it's so painful
and i don't even have an HDR screen
then you introduced fake aliasing and extreme artefacting. the scanner did such a good job and how you massacred their boy

and again
the limits per one page are absolutely sane and proper. one page of information per allocated file size
but limits per chapter are illogical, when one chapter can be one page and another can be 200 pages. and then i could just split it into two fake chapters and no one would've noticed

for a second you got me worried but the whole chapter is below 600 mb like it's the early 00s

what's 1/22? you mean 1, 22? the cover? yeah you are right it's 2+pages in one image so it went over.
but 22 is 7,51 mb

 

[Thatusernamehasalreadybeentaken]

anyway what am i supposed to do now? i can't edit the uploaded files, so i just need to delete them and upload instead mangadex-exclusive overcompressed jpegs?

200/70=2,8 mb per file

oh
my
ies

I levelled it, you didn't bother. You are confusing printing/scanning artifacts with intended detail; look at digital releases of manga, and you won't find any of the grainy artifacting present in your upload. The images are SDR, I do not know why you're bringing HDR into this.

then you introduced fake aliasing and extreme artefacting. the scanner did such a good job and how you massacred their boy

There is no "fake aliasing and extreme artifacting" and the scanner didn't do a good job; it's a scanner. You'll always need to clean up the output, because anything you're scanning has gone through at minimum two destructive processes (digital master, printing and scanning) or even more in this case (physical master, copied, printed, scanned) and is going to look worse as a result. All I did was level the output to compensate for this. No antialiasing, no quality loss, it's just a slider.

but limits per chapter are illogical, when one chapter can be one page and another can be 200 pages. and then i could just split it into two fake chapters and no one would've noticed

Our bandwidth isn't free, not all users don't have fast internet, and when the existing chapter limit is over TWENTY TIMES the average chapter size we're already giving people a lot of leeway.
The official English release of the Bakemonogatari manga averages about 140mb a volume; you could upload two entire volumes, 400 pages, in one MD chapter and still not hit the chapter size limit. It's not unreasonable.
Splitting chapters arbitrarily breaks rule 3.2.2, fyi.

what's 1/22? you mean 1, 22? the cover? yeah you are right it's 2+pages in one image so it went over.
but 22 is 7,51 mb

I'm going off the internal numbering; page 22 in the upload is the colored insert. This single image is larger than most chapters on MD.



EDIT: Also, you can edit your uploaded chapters by going to the series page and clicking the edit icon on the chapter.

2.2MB, even keeping the horrific scanning artifacts intact. More than twice the size of the first version I posted, it looks worse than mine, but you can still upload over a hundred pages of that size. All I did here was export it as greyscale instead of RGB, which has a nice side effect of removing the yellow tint in the original scan caused by the aged paper so it looks slightly nicer than your original upload at 40% of the file size.

This change brought the portion of the chapter you uploaded down from 282MB to 101MB.

so you don't really understand what you are talking about, k.

if you think we are still living in the 1990s, and mind i am a hobo in a terrible third world country, and even we still don't live in the 1990s anymore. i am not arguing against the individual image limits make it 150kb for what i care, i'll compress them to 150kb for you if it says so. i'm arguing against the stupid chapter policy, not against the sane page one.

in this case i literally could split them into three going for magazine release, but the source is TPB so i went with that numbering

 

[BraveDude8]

so you don't really understand what you are talking about, k.

I understand what I'm talking about because I get paid to work with image/video optimisation. You clearly don't, because you think scanning artifacts and poor levelling are signs of quality and I've managed to make your images a third of the size with no visible changes, or a sixth of the size with a visual improvement with about thirty seconds of work.

if you think we are still living in the 1990s, and mind i am a hobo in a terrible third world country, and even we still don't live in the 1990s anymore.

You are not representative of every user, and neither is your internet connection.

i am not arguing against the individual image limits make it 150kb for what i care, i'll compress them to 150kb for you if it says so.

This would be retarded and pointless. Why would we do this?
Individual images need to be more than 150kb, individual chapters do not need to be more than 300mb.

i'm arguing against the stupid chapter policy, not against the sane page one.

The chapter limit is there, among other reasons, as a final check against people uploading incredibly unoptimised chapters (like yours) that will bloat our servers and waste bandwidth. The uploader has a multi-stage image optimisation process built into it, but your upload is so unoptimised that it barely made a dent.
Again, if you'd like to offer an actual argument as to why your upload needs to take up approximately thirty five times the space of an average chapter, I'm willing to hear it.

in this case i literally could split them into three going for magazine release

No, you couldn't, because the contents page in your upload says the first chapter runs from page 7 to 70.

 

[Thatusernamehasalreadybeentaken]

i think we are from very different generations. you grew up with a screen and you work for a screen. you hate books but i have thousands of them. you think bitcrushed imagery is good, i think clear lines and soft imagery is good. boomers think blurry low res ugly giant CRTs are good and superior to LCDs, and also blury ugly terrible lowres physical film, i think crisp aspect corrected pixels are good, and i think high res digital cameras with no crawling maggots are good.

when you have per page limits it already limits the bandwidth, per chapter just puts people who work on tiny chapters and people who work on big chapters in unequal conditions

i could've used magazine covers and not upload that page, and as you can see i'm the first person in 50 years who is touching that comic no one would've noticed. that's why the per chapter policy is stupid it punishes honest people and encourages trickery

oh and the problem is the lack of any feedback on the site. as you said i uploaded 2 images over 20 without noticing. and as you say i went over the 200mb limit. and the interface is not good to begin with. like the site pretends it accepted 30 pages and then reloads the page with no feedback. what now? waiting for the page to refresh? there's no warning

Like this comment if you have books

I have 10 dollar second hand monitor, so all looks the same to me.

i've got a uws uhd 40" for free in the early 10s

i combined three panels of screens from 00s i got from a closing office

modern backlit low end 65" 4k are very cheap when your country doesn't have a trade war with china

LMAO.
I have a number of books and I do like the look of them over digital, but that's all subjective. Objectively print is a lower quality compared to digital (at least compared to the original master). Add in artifacts from scanning from a print and you get something even further from the truth.

 

[Thatusernamehasalreadybeentaken]

yes, but then bitcrushing the raws, violently aliasing them and turning them into 100% light with 100% dark is even further from a a natural light reflecting from a page

and this is 1975 release it was physically mastered for print not for oled ghettoblaster 100000 nits hdr, it was made before any compluctors

 

[Manko-sensei]

It seems you simply needed either a long talk or venting, for the latter we have an excellent thread in Lounge called "Tell us, what's bothering you?", you can make a looong post without needing a staff member looking after you. Since we're reminiscing the good old days in the past without World Wide Web ranting like this costed money, time and either good hand-writing or a typing machine, and with that verbosity all your letters would be scrapped by the secretary. Or you could go with your complaints straight to the office in person to meet the fist of justice.

Just gonna leave this here...

 

[RogueKitsune]

Bitcrushing, you keep using that word, but I didn't think you know what it actually means. As for the rest of your statement all of that is artifacts of the printing and scanning process.

When the image is printed on paper it doesn't perfectly cover every fiber which result in a more washed out color. Add in some time and things get slightly worse. Next when that aged print is scanned (particularly with the most common type of scanner) those print artifacts are enhanced (i.e. lines become soft and noise is introduced in solid fill areas).

 

[Thatusernamehasalreadybeentaken]

white 1 black 0 two bits

and your offer on top of that all is to ai slop all of that into 100% black and 100% white, boost all the artefacts and use max contrast to destroy human eyes with direct light

ai slop doesn't magically restore already lost information
