As everyone knows, any story that goes a helicopter instantly improves. And it is not the same stroll through Barcelona to test the latest camera or mobile to portray and save the city from the sky.
Aware of this, Sony Mobile chose to celebrate in style-pun intended-the arrival of your Xperia Z2 at the Mobile World Congress and took the helicopter ride press. A good opportunity to premiere the video recording mode with 4K counts based on Android and this is undoubtedly one of the most outstanding new smartphone.
It is true that, from a strictly technical point of view, are not the best circumstances for this test: a crystal interposed between the camera and the landscape, the harsh light of midday, it was three in the afternoon-the constant shake a helicopter ... But the truth is that it was one of those proposals that is hard to resist.
Half an hour of flight and travel back and forth between Barcelona and Montserrat-record we try to best-in 4K. Are We Ranked footage? Not as much as one might fear a priori, with a rate of about 400 MB per minute of recording. Something that logically implies that it has a rather high compression applied with corresponding effects on the fine details of the image.
This first test gives a fairly predictable results. The quality is good, at the height of the best Full HD video that can be obtained with a smartphone, but four times larger (3840 x 2160 points). After all, for that matter.
That 4K is here to stay is evident. Take more or less sneak into homes, but so far as the recording devices are doing their homework.
But it is a mobile, of course, so you are also limitations there. For example, there are obvious problems with the dynamic range and the rolling shutter effect, clearly seen especially in the higher levels of jitter. The new image stabilizer does its job, but it is true that in such extreme conditions can not expect miracles.
But does it make sense to record 4K video with a mobile? Is the obvious question whenever a device with this functionality hits the market, and the new Xperia Z2 is no exception. While it is true that without some resolution of this TV can do, the good news is that YouTube already allows us to store the videos on this pending resolution have a display conditions.
In any case, there is only 4K. Record clips with this resolution can also be an advantage when performing post production and full HD video mount leveraging that excess pixels to improve the bottom line.
Actually this is the same debate at the time lived around high resolution. That 4K is here to stay is evident. Take more or less sneak into homes, but so far as the recording devices are doing their homework. Sure like to have some advance too.
