I think there is a fundamental-misunderstanding in that…

You can fake resolution, but you can’t create it, once you’ve thrown it away, with lossy-compression.

The brilliantest example ever, was given like this ( had to do with “universal file compression” scammery, last-century )

Say you’ve got 4 files, that are 2-bits long:

• 11
• 10
• 01
• 00

& you compress them all down to 1-bit, so now you’ve got 2 compressed files:

• 1
• 0

… how could you de-compress them back out to 4 separate files?

The information’s GONE.

You’ve only got 2 left, right?

The same is true for compressing media-files.

I wish all the quote-images were done in SVG, all the audio was in OPUS, & all photos were in JXL, simply because that seems to be the optimal solution.

I wish the best video-format ( that isn’t patent-encumbered ), AV1 or something, were normal, too.

It isn’t that there is some specific video-resolution which is required, for the archived quality, rather, it is that there is some specific information retention that is required, & some of that information may have to do with resolution, other may have to do with color, other may have to do with motion, etc…

so it isn’t specific-resolution, rather, it is specific-percentage-of-information-discarding that is what’s being done…
