BlackBerry Passport to support 4K video recording?
BlackBerry is coming up with a new “differently sized” Passport smartphone that every BlackBerry enthusiast is looking forward to. We have showed you how it got completely exposed in one 28 minutes long video, they say it “pre-review” video. But now its something related to its video camera situated on the rear panel. One twitter user was able to dig out the screenshot of BlackBerry Passport’s screen which clearly shows “4K video at 30fps” for rear camera. However, BlackBerryOS folks says:
Remember, the specs of the BlackBerry Passport will have a 13MP rear camera so it is likely that we will see 4K recording on the Passport.
The 4K feature seems to be in testing only and will probably not be available when the release of the Passport happens but will be added to OS 10.3.1 if it passes the testing phase.
So what’s this 4K video recording means? Yes, many would rise this question. Its actually the double of vertical lines in 1080p resolution. StreamingMedia explains:
There are three 4K resolutions to consider, each with a different aspect ratio.
Let’s consider, first, the DCI version of 4K. The film industry likes to shoot at resolutions at least 3-4 times greater than what it will project, so the DCI came out with a 4K specification at the same time it came out with the 2K display specification.
DCI 4K has 2160 vertical lines of resolution, which is double that of 1080p. So far so good, but what about the horizontal resolution? It clocks in at 4096 pixels. All told, that’s 8,847,360 pixels, or 8.84 Mpx.
Running the numbers, that means DCI 4K is 4.26 times the resolution of 1080p and exactly 4 times the resolution of 2K. The difference, as we mentioned above, is the aspect ratios of 1080p (16:9) and DCI 2K / 4K (17:9).
