Rheet Shull's video is quite high quality and shows it.
When it was published I went to Youtube's website and saw Rick Beato's short video mentioned by him and it was clearly AI enhanced.
I used to work with codec people and have them as friends for years so what TFA is talking about is definitely not something a codec would do.
After posting a cogent explanation as to why integrated AI filtering is just that, and not actually part of the codec, Youtube creates dozens of channels with AI-generated personalities, all explaining how you're nuts.
These channels and videos appear on every webpage supporting your assertions, including being top of results on search. Oh, and AI summaries on Google searxh, whenever the top is searched too.
