My friend got one of those new swanky Xiaomi phones that can do 120 hz refresh rate. The problem is that YouTube doesn't support anything above 60 and I couldn't find anything on major torrent sites. Maybe this stuff is unlabeled? Hell, even 60 hz stuff is very sparsely seeded outside of 【Human wife love fellow No. 3 Exposed by taking a duck boat at a park on summer vacation!

Edit: Also, as long as we are talking about high frame rate video, check out 60 fps YouTube videos from Gemini Man, which was filmed in 120 fps. Shit's weird.
I once downloaded Gemini Man exactly because I was curious what those hfr movies were like. It was a huge hustle finding a 60 fps torrent. I don't think there's a 120 fps home home version of it despite it being 120 fps in the theaters. It seems like a hfr wasn't been released on blu-ray at all.
Funny thing is that the guy bought this phone partially because his old one didn't run Genshin Impact all that well, but the new one still doesn't go beyond like 40 fps.
I believe there's a technical limitation to Blu Ray, which means it can only be 24/30 or 60 fps content. My understanding is that this is why the Hobbit trilogy was never released at 48 through legitimate channels.
