Well that didn't last very long. It was 8 MB for like six years and then it just went to 25 MB maybe a year ago and now we're back down to 10 MB.

I'm surprised they aren't offsetting the cost by selling all our data to language learning models like everyone else is

Hah. Hahaha. Hahahahahahaahahahahahaha. HAHAHAHAHAHAHAHAH

[–] Jessica@discuss.tchncs.de 5 points 2 months ago (1 children)

Just to be clear, I 100% think they are selling our data. What I meant was I'm surprised they're concerned about the size of the uploads when they could just be selling the uploaded data.

[–] tetris11@lemmy.ml 1 points 2 months ago

Good point. Harder to parse would be my guess

[–] 30p87@feddit.org 9 points 2 months ago (1 children)

And standard screenshots of my desktop are ~30mb, I was lucky to upload it lol

[–] B0rax@feddit.org 11 points 2 months ago (1 children)

What format are you saving them in? BMP? Try png.

[–] 30p87@feddit.org 5 points 2 months ago (3 children)

I am using png. Level 0 compression tho and in 4k (3840*2160), sometimes even 4k + 2*1440p (2560*1440), but it's already too large with just my main 4k monitor.

Because it was never a problem. It's a little bit faster for encoding and decoding, and no service ever had problems with the file size. Especially not my selfhosted stuff. Every service, except discord. As I now have resorted to using Vencord or just uploading most media to Nextcloud, I don't have that many issues with it anymore, anyway.

[–] nekusoul@lemmy.nekusoul.de 3 points 2 months ago (1 children)

It’s a little bit faster for encoding and decoding

On the other hand, the time spent uploading/downloading much smaller files probably more than makes up for that, although even that difference might get pretty small with modern internet connections.

[–] 30p87@feddit.org 1 points 2 months ago

Especially in times where using WiFi is faster than ethernet, because my network ports are only gigabit.

[–] JackbyDev@programming.dev 5 points 2 months ago (1 children)

You know PNG is lossless compression right?

[–] 30p87@feddit.org 3 points 2 months ago* (last edited 2 months ago) (1 children)

Yes. But in theory it's still a performance hit, and as I have enough local storage (and typically use services with high limits), and I'm too lazy to change grims config just for discord, I never changed it and used Vencord instead.

[–] JackbyDev@programming.dev 1 points 2 months ago (1 children)

Why do you think it's a performance hit?

[–] 30p87@feddit.org 2 points 2 months ago (1 children)

Because even though it saves over 29 MB, it also takes more than 20 times as long. And that's just on my laptop, 1920x1080 + 2*1680x1050. On my PC it's even worse.

I have thousands of GB of high speed storage, Gigabit internet, but only a Ryzen 5 2600 and a i5-1145G7.

[–] JackbyDev@programming.dev 2 points 2 months ago

What about compression level 1 instead of 9?

[–] tetris11@lemmy.ml 3 points 2 months ago (3 children)

PNG started out as ZIP(BMP) and hasn't gotten that much better. Use JPEG. The pixels you lose are not worth crying about

[–] lemmyingly@lemm.ee 12 points 2 months ago

Or they could just compression for their PNGs. PNG is a lossless format so they'll only lose a fraction of a second during creation.

[–] B0rax@feddit.org 10 points 2 months ago (1 children)

JPEG for graphics like screenshots is not very efficient. For stuff like that, png is simply superior. (But not with compression 0)

PNG is not good for photos though.

[–] tetris11@lemmy.ml 1 points 2 months ago (1 children)

why though? The graphics represented in the screen are already squashed and scaled, so you wouldn't be preserving their quality in any case. If you're worried about text, JPEG should still be able to handle it under high quality settings

[–] B0rax@feddit.org 6 points 2 months ago (1 children)

We can ask the same the other way around: why do you want to use jpg if it results in a bigger size and worse quality than png?

[–] tetris11@lemmy.ml 1 points 2 months ago* (last edited 2 months ago) (1 children)

But that's patently untrue: take this 10 MB example TIFF file as an example.

  • PNG Compression, max compress (=quality 9):

    convert file_example_TIFF_10MB.tiff -quality 9 test.png
    
  • JPG Encoding, 99% quality (=quality 99):

    convert file_example_TIFF_10MB.tiff -quality 99 test.jpg
    

Final file size comparison:

9.7M Sep  5 13:21 file_example_TIFF_10MB.tiff
1.7M Sep  5 13:22 test.jpg
2.5M Sep  5 13:22 test.png

PNG is significantly larger, and difference in quality between them is negligible

[–] B0rax@feddit.org 4 points 2 months ago

Dude. Did you even read what I wrote? PNG is bad for photos. Your example is a photo. Go ahead and try the same with a screenshot with text and menus showing.

[–] 30p87@feddit.org 2 points 2 months ago (1 children)

I use 4k because I like seeing a lot of stuff at the same time in good quality.
I make screenshots of my whole screen to share all the stuff in the highest detail.
Using jpeg would result in literally unreadable pictures.

[–] VOwOxel@discuss.tchncs.de 1 points 2 months ago

Depends on the Quality setting and version of jpeg. Even the original jpeg, on high quality, will result in little to no data loss. IIRC, Jpeg can even do lossless, with the only caveat being that it doesn't save alpha channels (but screenshots don't need to have transparency, anyway). Newer versions of jpeg, such as jpeg-2000 (and the much less broadly supported jpeg-XL) have much better compression and provide higher image quality at lower file size.

"jpegification" or "Deep-frying" only really occurs with the original jpeg at low quality settings.

aren't they doing it? but at least by looking at how much they like locking out people until they give out their phone number, I suspect they are not collecting it without having further use for it

"by selling all our data to language learning models like everyone else is"

I imagine China is using it for free since Tencent owns a 38% stake.

[–] gencha@lemm.ee 1 points 2 months ago (1 children)

They increased to 25 to encourage media uploads to train their own models with. They now have collected enough metrics to realize, most valuable content is below 10MB. Now they are optimizing. They won't lose anything valuable to them and the users who are impacted might even buy Nitro now. Win-win for them

[–] lud@lemm.ee 1 points 2 months ago (1 children)

It would be legally stupid for them to abuse that.

[–] gencha@lemm.ee 1 points 2 months ago

https://discord.com/terms#5 is pretty permissive

Wait, I ~never was notified that it got to 25mb, I thought it was 8

[–] Jessica@discuss.tchncs.de 2 points 2 months ago

It might have only even been like six months. It was in the little change log pop up during one of the updates at some point
