LynneYoutube has started doing AI upscales. Be careful what you archive from now on.

@lynne I feel like it should be excluded/lower-ranked from best/bestvideo.

These formats will likely be deprioritized in the near future, but doing so correctly will require some non-trivial core changes that will take more time and effort than simply implementing detection of the formats.
Oh neat!
RedTechEngineer@lanodan @lynne I wonder how good these upscales are.
If nothing else, the extra bitrate should help quality so if the upscales are done competently, it could actually be good.
Though if it's being done en mass it's probably a sloppy smeary mess.
Upscaling video at home, competent scalers give me around 0.025x realtime on a AMD AI max APU, so I don't have much hope.
Do you guys have any URLs with these upscales?

@RedTechEngineer @lynne Depends on what you mean by quality I guess but I would 100% expect a degrade in information quality as it's not something comparable to say restoration work which while you can use tools is still very manual.
Plus I would be very surprised if youtube also kept videos in their original bitrate so you're probably not going to get any information back.
So even best case, what you'd get is maybe better rendering on higher density displays compared to more classic upscaling done by video players.
But for archival? Information loss it is.
