What is a video's maximum framerate that an iPhone can play?


Recommended Posts

Hi all

Sorry for the confusing title its a difficult question to put in to words and i can't seem to find my answer in google.

Anyway, I know that the iphone can only record at 30fps, but can it play a video at 60fps or more? and what version of iphone can play what...

Also, if it is able to play 60fps video, is it just downscaling to 30? or would it just give an error that it cant be played.

Cheers :)

It can play video up to the refresh rate of the display. Since the iPhone uses an LCD I'll assume that it has a refresh rate of 60Hz. If that is the case, it can't go any faster than 60FPS as anything faster than the screen refreshed rate is wasted.

CPU/GPU-wise, it can play videos at hundreds of FPS, but the screen likely limits it physically to 60 FPS. However, I believe iOS caps videos at 30 FPS no matter what.

the human eye sees things at 29.97fps or some silly **** cant rember where i read it so it would be pointless to do video higher

:rofl: 29.97, what a coincidence! :woot: I don't even...

hahaha... are you sure its not 23.976 :p

For the record, the whole 'why bother with higher framerate due to your eyes seeing x amount of fps' is wrong.

Your eyes are used to seeing the real world which is run at infinity fps, Assuming that you are not on drugs, everything you look at will be very smooth. Electronic displays are limited to the amount of fps it can dish out. Because you can not sync your eyes to capture 29.97 frames per second with an electronic display, you will sometimes see half a drawn frame or even the same frame twice, or skip one frame out of 3 etc.... depending on how good your eyesight is, the amount of fps can vary quite a bit. So to compensate, the closer to 'real life' an electronic display is, the smoother it is. Play a game at 60fps with 60hz, then play a game at 120fps at 120hz, you will notice a huge difference.

I guess the new movie "The Hobbit" being filmed in 48FPS is a lie lol
