[Z2 Xperia, Galaxy Note 3 S5 and only allow the recording of 4K video ... - Xpert Mobile

Video recording in 4K has been trying to scratch, lightweight, the scenario of mobile devices. The adoption of the new function is still limited, but some manufacturers are now incorporating into their premium devices. Some of the first devices to offer 4K video recording are the Galaxy Note and Galaxy 3 S5 as well as the Sony Xperia Z2. We’ve seen a test camera of Xperia Z2.

However, although these devices are officially able to record 4K video, they do not offer an adequate user experience, as they can only record no more than five minutes of footage in 4K resolution. Of course, this does not make much difference to most users, considering that make short recordings mostly. But even so, five minutes will be very little for those who wish to write a longer event, since the recording stops after this time.

We’re not sure why manufacturers are limiting the

time of recording of 4K video in five minutes. But we have a clue left by Sony Xperia Z2! While the Galaxy Note 3 and S5 are strictly limited to five minutes of recording, the Xperia Z2 has no time limit. What determines the order of recording the Xperia Z2 is the internal temperature. When things start to get very hot inside there, the recording application is closed.
 

To give you an idea, starting a recording in 4K Xperia Z2 in a room with air-conditioning at about 25 ° C, the device can keep recording for almost five minutes. At this point the unit becomes very hot and the application is closed. If we start another recording soon after the first, the Xperia Z2 will record just over two minutes. Outside the phone the temperature reaches about 44 ° C! The Galaxy Note 3 and S5 do not heat the same way, perhaps because of the material to which they are made. Perhaps best dissipating heat.

is important to note that the limiting time recording in 4K Sony Xperia Z2 is just the temperature. There is no time limit. When it is placed near an external cooling can record much more than five minutes. Another limitation is the internal storage, whereas 10 minute video in 4K will cost you 4GB of space. The video recording in 4K is still in its infancy, but it may be that over time it will begin to walk on their own feet.
