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

How to avoid Youtube's new "Super Resolution" AI-upscaled formats · Issue #15325 · yt-dlp/yt-dlp

babble encat@lynne Oof. I assume the yt-dl folks de-prioritize that in their "pick best format" function
TerrorBite 🦁@babble_endanger @lynne they are working on it but it's not implemented yet, “core changes” (no idea what that involves) are required first.

stefan (stefbun)@lynne Its nice atleast they tag it as such. Maybe one could ask to add a flag to yt-dlp so it never downloads AI-upscaled when thats set
Sven Slootweg, low-spoons mode ("still kinky and horny anyway")@lynne FWIW, there's a yt-dlp invocation here to exclude the upscaled versions from the format selection: https://github.com/yt-dlp/yt-dlp/issues/15325#issuecomment-3652334462
(Also, alt text: a screenshot of yt-dlp showing the available formats for a video; some of them are marked as "AI-upscaled" in the format comments)

Hugo Devillers@lynne Google is about to bring a whole new meaning to the term “generational loss”
cmdrSprocket@lynne and at the same time YouTube constantly switches to 240p for me.

🇵🇸 Amanda@lynne @antifuchs What does “AI upscales” mean please? I’m super comfy in a command line but the utility in the screenshot isn’t familiar to me. Thank you! 🙇🏼♀️

mmu_man@lynne there's a syntax for the -f option:

RandomMusickMayhem (ON HOLD)@lynne All videos with AI upscaling were clearly tagged as such in the title or video description. No malicious upscaling until now.

Microfractal 🫖@lynne Is audio data also affected?
Leonardo Ferreira Fontenelle@lynne my favorite video on YT upscaling so far:

@lynne I feel like it should be excluded/lower-ranked from best/bestvideo.
@lynne https://github.com/yt-dlp/yt-dlp/issues/14923#issuecomment-3539437820
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.
