It's a hardware feature,
4K means 2160p or 4K pixels.
Z1 only records in 1080p and its maximum pixel for recording in its lens is 1080p, so 4k in Z1 is impossible.
Hit thanks if this helped you!

But it's exactly the same hardware with the same camera and the S800 of the Z1 is able to record 4k ... that's why i ask about it

That's only a software issue and i think that Sony can introduce 4k in Z1 ...

According to Qualcomm, the new 801, not sure which 801 variant, has h.265 support built in, HEVC

http://www.qualcomm.com/snapdragon/processors/801

This is missing in the Z1, and therefore any official support for 4k video from sony will probably not occur, unless they decide to use h.264 for 4k, but then files will be rather large. If the 4k on the Z2 is dependent on h.265 support I am not sure how easy it can be ported over to the Z1. Yes the S800 does have ultraHD support for playback and capture, so perhaps 4k capture will be ported over or even possibly added by Sony, but I wouldn't hold out on the latter.

z2 does not suport h.265 encoding according to sony white paper: http://dl-developer.sonymobile.com/d...D6543_WP_1.pdf

its exactly like z1 and z1 compact:

so this shouldnt be a problem

dude do you realise the amount of trash you just said?

first - z1 camera sensor and lens are the same as z2
second - according to your logic the lens cant capture more than 1080p videos (2mp), but it can take 20.7mp pictures. how is that possible haha

@OP: the only diferences are the S801 clocks that are a little bit higher than s800, and 1GB of extra ram that z2 have. but i dont think this should be a problem, since any S800 chipset has the ability to do 4k recording and GS5 and Liquid S2 have 2GB of RAM and also record 4K 30fps (it doesnt suport video stabilization though)

that's a shame, why would sony opt for h.264 4k encoding when the 801 has native support for h.265?

4K is useless on a smartphone with little lens
It pumps up the resolution but the quality remains substantially the same

It could be introduced via software and currently the only real benefit would be to fit better on a 4K display without upscaling processing
The problem is the potential lag because the hardware (CPU, GPU, less RAM), but it should be ok (the differences are minimal)

I'd like to see implemented timeshift video on Z1

That makes no sense that we are capped at 1080p. If the camera can take 20mp images that the lens and hardest are there to capture it. The hardware to push it to memory fast enough is a different story.
