No way media compressed 5x.

Maybe they store images as uncompressed .bmp for some reason

[–] Lichtblitz@discuss.tchncs.de 4 points 10 months ago (2 children)

bmp should not compress more than other media files. jpeg, png, etc. can compress so much because they are lossy

You're right. png can be lossy but that's uncommon in the wild.

[–] Anafabula@discuss.tchncs.de 4 points 10 months ago* (last edited 10 months ago) (1 children)

Three files of the same image: A png (15.7MiB), a bmp (28.8MiB) and a bmp.zip (16.4MiB)

PNG actually uses the same compression algorithm as ZIP (DEFLATE).
Here are the files.

The image doesn't look like a photo. The meme is about porn. Digital images can contain large areas of repeating patterns (uniform color areas for example) that can be compressed losslessly pretty well. Even slight noise from an image sensor can block that kind of compression.

With a picture from Unsplash:
Three files of the same image: A png (34.5MiB), a png.zip (34.5MiB), a jpg (4.9MiB), a bmp (98.2MiB) and a bmp.zip (65.1MiB)

ZIP compression of bmp is worse, but still compresses more than png. Here are the files.

Fascinating. That's much more than I expected. Thanks for taking the time.

[–] reev@sh.itjust.works 2 points 10 months ago

Was thinking the same thing

[–] hmmm@sh.itjust.works 0 points 10 months ago (1 children)

Why are you surpried? It's actually possible. You just need so much computing power like around 64 GB ram and High End CPU to Pack and Unpack both.

[–] abfarid@startrek.website 8 points 10 months ago* (last edited 10 months ago)

Because modern media files are already compressed by default and have very little redundancy in them.

WinRAR got me through some hard times. She might be filthy, but she did the job

[–] TheTechnician27@lemmy.world 12 points 10 months ago (2 children)

She's proprietary nagware, and 7-Zip is better in every way.

[–] bruhduh@lemmy.world 14 points 10 months ago (1 children)

Say truthfully, when you was 7 y.o kid, did you used fully open sourced OS then? I think everyone used winrar when they were kids/teenagers (before learning about foss)

[–] ArcaneSlime@lemmy.dbzer0.com 2 points 10 months ago (1 children)

I used winrar until I found out about 7 zip around 2003-4ish, but I still used 7z on windows back then tbf. Just using 7z and VLC on windows simply because they're better doesn't mean you have to be Stallman.

[–] bruhduh@lemmy.world 1 points 10 months ago (1 children)
[–] ArcaneSlime@lemmy.dbzer0.com 1 points 10 months ago (1 children)

...shit honestly I used winsomething until 7z, but you got me I can't remember if it was -zip or -rar, damn similar names +20yr!

But in either case, "the rest."

[–] bruhduh@lemmy.world 1 points 10 months ago (1 children)

You don't remember this brotha?

[–] ArcaneSlime@lemmy.dbzer0.com 1 points 10 months ago* (last edited 10 months ago)

Guess I used winrar back then, 'cause no.

Hol' up is that a music player? Definitely no. For video it was VLC pretty early, WMP before that because it was preinstalled but the second it didn't play something and the advice searching gave was "vlc will play the file" I never went back. I don't remember what I used as a media player tbh, foobar for a while for sure but it was definitely something before that. Hmm, what the hell did I use?

..i think I may have just used the preinstalled WMP until VLC/foobar, huh. I did have a zune when those came around too and used that software, but mostly to interface with the device not play my library, then I did the registry edit so you didn't need that anymore, and I think I used foobar before that, definitely used vlc before.

[–] admin@sh.itjust.works 2 points 10 months ago

I didn't discover 7-zip until 5th grade, so WinRAR always takes a spot in my heart <3.

[–] GrammarPolice@lemmy.world 1 points 10 months ago

I use Windows in-built extract

[–] bruhduh@lemmy.world 14 points 10 months ago (2 children)
[–] hmmm@sh.itjust.works 2 points 10 months ago

Seriously I don't know maybe you reverse search this.

[–] MrLLM@ani.social 1 points 10 months ago

OP’s computer

[–] superkret@feddit.org 10 points 10 months ago

Is this lossless?

[–] alsaaas@lemmy.dbzer0.com 4 points 10 months ago

What if it's on a BTRFS --compress-force=zstd:22 compressed subvolume?

[–] gandalf_der_12te@discuss.tchncs.de 3 points 10 months ago

you can't compress most media files again, they don't get smaller that way as they're already compressed. you can't compress files again, that's against Shannon Information theory.

Do Windows people often see .xzs? Does anyone?
