I don't think you know what "AI slop" means.

It's not making the videos look fake, any more than your iPhone does. Most of what's shown in the example video, it might very well be phones applying the effect, not YouTube.

At no point did I say the video IS AI slop. Or that generative AI was used to make it, or the effect youtube applied to it. We actually have no idea what youtube did. We only see the result; which can be subjective.

To you, that result looks like it was shot with a phone filter. To me it looks like it was generated with AI. Either way, it doesn't really matter. It's not what the creator intended. Many creators spend a lot of effort and money on high-end cameras, lenses, lighting, editing software, and grading systems to make their videos look a specific way. If they wanted their videos to look like whatever this is, they would have made it that way by choice.
