During the last week, ARM heart formalized its new Cortex A72. Apart from the many opportunities offered by the next generation’s processors that will be equipped, it is one that should be widely highlighted by manufacturers: 4K video capture at 120 fps.
Inaugurated by the Galaxy Note 3, launched in autumn 2013, and since then taken over by the most senior class of 2014, 4K video capture was one of many innovations put forward last year by the manufacturers. However, for now, it is still limited to 30 frames per second and it is hardly possible to shoot for more than 5 minutes without causing overheating of the unit.
With the new ARM Cortex A72, probably expected in the future processors Snapdragon 618 and 620 from Qualcomm and its VPU Mali-V550, it will be possible to shoot Ultra HD at a rate of 120 frames per second. In other words, it will also be possible to create slow motion in 4K, slowing up to five times (at 24 fps) the speed of the video.
If this type of functionality remains accessory for the average user, the Ultra HD video capture has nevertheless established itself last year in the image sensors of our smartphones and it will probably even next year with the 4K to 120 fps.
At present, when it comes to film at 120 frames per second, Android smartphones are still limited to HD 720p resolution. Once in Full HD video capture, it then goes to 60 frames per second. The video can then be slowed up twice. So this is a major breakthrough that is preparing the side of the mobile video capture.
