The OnePlus 7pro is capable of 4K at 60Fps and the Redmi Note 7 Pro also has the same 48MP sensor. So is it possible to record 4k videos at 60fps in Redmi Note 7 Pro?
The camera sensor (IMX 586) on Redmi Note 7 Pro supports 4K@60Fps but the SOC which is the Qualcomm® Snapdragon™ 675 only supports up to 4K@30Fps. Below are the camera capabilities on a Qualcomm® Snapdragon™ 675 SOC.

So it is clear that you can shoot at 4K at 60Fps however maybe with a custom ROM and mods you can do I20Fps High Frame Rate video.
Okay, so there isn’t a way to do that? The 1080p 60FPS and Slow Motion options in MIUI have a lot of frame drops, I hope Xiomi fixes this in future updates.
Some people claim a moded Gcam will allow this. Idk how legit it is! here it is MGC_6.2.030_DCIP3Version_Bulkin043_V8.2.apk
