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 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.
