That advice is not universal, and without context it's simply wrong.

You wouldn't upscale a classic film in this way, but there are plenty of low-resolution shots that benefit. Especially with VGA resolution renders and modern AI workflows.

Just looking at the Topaz marketing, you can see a lot of places where it indeed does work. And 20-year industry professionals are using it today for their day jobs.

If you want to say "don't upscale a classic film in Topaz", say that. Because context makes the advice correct. This blanket "do not use" statement is flat out wrong.

In any case, blindly apply upscaling is just wrong ..

You apply it to where it is needed. Not every scene need the same treatment.

The article simply says "Trust me, just don't."

No it doesn't. It says “don't, Unless you're extremely surgical with it and know exactly what you're doing”.

Which is a sensible piece of advice.

> Don't use Topaz AI, Anime4k, RealESRGAN, RIFE, etc. Trust me, just don't.

Is what the submission says about Topaz and similar.

> Applying any kind of post-processing[4]

Is what the footnote you quoted is linked to.

[littlestymaar]

There's no mistake, “Topaz and similar” == “any kind of postprocessing”.

[embedding-shape]

Right, but since the "AI upscaling" "advice" is more specific, doesn't that take precedent?

> Do post-processing if you're surgical about it

> Don't do AI upscaling regardless, never do it, and don't even ask why

Is the impression I get from this article.
