Along with Other Brands, Sony’s Xperia Z2 Comes with 4K Video Recording
by Stephan Jukic – August 4th, 2014
Now that 4K is growing in momentum all over the place, it’s also finding its way into all sorts of places, such as one of the key video recording features on all of the latest flagship smartphones of major manufacturers.
The pioneer in this area was Acer, with its Liquid S2 phone line and soon after others followed. So far, these include Samsung, LG and Sony. LG’s G3 phone comes with 4K video recording and so does Samsung’s S5 smartphone but Sony is the focus here with 4K video filming and photo capacity in its recently released Xperia Z2 and the upcoming Z3.
In terms of look and many features, the Z2 borrows a lot from its predecessors, the Z1 nad Xperia Z, but other new touches have also been added by Sony, most notable, built-in 4K video recording.
The Z2 features as 5.2 inch Full HD screen with 1920 x 1080p resolution, so in that area nobody’s yet getting 4K screen resolution from Sony but the device’s 2.3 GHz Snapdragon 801 processor from Qualcomm, supported by 3 GB of RAM and a 16 GB internal storage drive with microSD support, creates a very powerful processing engine for the phone’s 4K video recording abilities.
Furthermore, the 3,200mAh battery and 20.7 megapixel photo camera with a built-in Exmor sensor make for some truly spectacular prolonged photo shooting abilities on this smartphone.
The specifics of the 4K shooting ability on the Xperia Z2 are that it can give you several minutes of recorded 4K film at a rate of 30 frames per second and that it comes with a SteadyShot image stabilization feature. Of course, the video will only play back at HD resolutions on your phone but connecting it via HDMI to a 4K capable display screen or TV allows for viewing of your 4K shots in their full 3,840 x 2,160 pixel glory.
30 frames per second isn’t nearly as good as what a more robust independent 4K video camera will give you but it is comparable to the 4K capabilities of many UHD DSLRs, so really, not too bad at all for a little smartphone.
In addition to the 4K shooting features, the Xperia Z2 comes with Timeshift video capacity, which will let you shoot and edit slow motion video at 120 frames per second in 720p resolution settings.
One reported problem with the Z2 (and a number of other 4K capable smartphones such as those from LG and Samsung that we mentioned above) is that they only allow a few minutes of 4K shooting before cutting it off. Now this is probably a quirk that stems from the sheer processing requirements of 4K video but it’s also something that’s likely to improve quite soon since we’re just now seeing some of the first 4K video capable phones ever coming out onto the consumer market.
The Xperia Z3 is expected to go on sale in a few months or less, so we’ll have to see if its version of 4K video recording is improved and free of odd time restrictions.
As for the much rumored feature of an actual 4K resolution smartphone display, that might take a bit more time before Sony or anyone else is selling it.
