There are smartphones that allegedly write 4K 60fps but in fact 4K30fps or 4K45fps...?

Question

Mobile devices

Hello, please tell me if you buy a smartphone that writes 4K 60fps video, is there such a possibility especially among the Chinese (Huawei, Honor, Maizu) that smart records part of the video 4K 30fps or 4K 45fps at the hardware level (really) and part 4K 30fps or 4K 15fps programmatically draws (interpolation) ?

Answer 1

It is safer to buy a used iPhone. and the price will be about the same

Answer 2

Judging by your questions, you choose a smartphone and want everything to be to the maximum.
It is better to choose by quality and real reviews and not by numbers
. Unfortunately, beautiful is a subjective parameter, and a qualitative comparison can be obtained numerically by shooting in the same environment, i. a person should have several devices on their hands.
In reality, reviews are done with a maximum of 2-3 devices on hand (comparison) and if A is better than B by one reviewer, and B is better than C by another, this does not mean that A will be better than C !
ps 4k 60fps is shooting at the limit of existing technologies, and if the hardware is not stuffed with something like hardware video stabilization, then either it will not be in this resolution or it will be software and therefore not 60fps
for example xiaomi redme note 8 pro has video stabilization only for fullhd 30fps and below, and there is no stabilization when shooting 4k30fps or even fullhd60fps.
And yes, only when using the stock camera application, since any other applications do not have full access to sensor control (for example, there is no access to manual focus)
ps You can stabilize the video with third-party software already on the pc

Answer 3

Right now, everyone has become smart, no one is lying with the parameters.
But now we need to think about the bitrate. Cheap phones can't process such a stream of data and write video at a low bitrate, resulting in high-frequency 4K daub.
In general, you need to watch real video examples.
