“Wow, that video looks so good.”

These days, we say this so much. The cameras on our phones and tablets have gotten so sharp that our videos look ready for Hollywood (almost). The 1080p, slow-mo and the fun filters go a long way to turning phone footage pro, but nothing compares to shooting in 4K. It just looks so good.

The Math

There are two kinds of 4K: 4K UHD (the standard for televisions and monitors) and 4K (what you’d see in the theater). In our breakdown, “4K” will refer specifically to the former, the format used by mobile devices.

A 1080p image renders with 1080 rows and 1920 columns. A 4K image roughly doubles both those numbers to produce a resolution of 2160 x 2840p. This results in four times as many total pixels. The 1080p image you had before would fit on one quarter of a 4K screen. That means four times the picture sharpness when shooting in 4K, a significant jump in clarity. Look at any comparison between the two images and you’ll see 4K is far deeper and more detailed –– the reason so many videographers are so excited about it.

Of course, that also means a significant jump in memory requirements. It’s hard to say exactly how much because this depends on your frame rates and your device’s compression technology, but here are some estimates:

  • 26 minutes of 4K = ~8GB
  • 53 minutes = ~16GB
  • 107 minutes = ~32GB
  • 215 minutes = ~64GB
  • 432 minutes = ~128GB

Next time you’re weighing memory options in the Apple Store or Best Buy, know that 4K will take up far more space on your mobile device than regular video. If you have already bought the lower configuration model of phone, or even one that only comes in a single capacity like the 32GB Samsung S7, you will be running out of memory far more quickly.

The Full 4K Experience

Away from mobile, you will want a TV that supports 4K. And you will definitely notice the difference, though as TechRadar puts it, “you might not feel the same thrill you did when you upgraded your old CRT to a flat screen.” You’re going from amazing picture to amazing-amazing picture. Also, because the pixel density is so tight, you can now sit closer to the TV and the picture won’t pixelate. That means you don’t need quite as big a TV as before. Get closer; immerse yourself in the picture.

Editing in 4K

Using a handy app like Apple’s iMovie for iOS makes manipulating that 4K video intuitive and easy, letting you quickly add themes, titles, and transitions. However, the files are beasts, so if you’ve been doing that editing on an older tablet or PC, and you want to make the 4K leap (because it will be the standard), then it might be time to upgrade.

The Storage Challenge

So you’ll need a place to keep all of this amazing footage, especially as mentioned, if you’re locked into a low capacity phone –– and even still, with 4K, you’ll run out of space on a high configuration phone pretty quickly too. Using a flash drive designed for your phone like the new iXpand Flash Drive not only helps manage content on your phone, but the newly redesigned iXpand Drive app has a special feature that lets you save video directly to the drive. That basically means you can shoot all the 4K video you want and the app will ensure you keep your phone space free for other important files. A pretty seamless way to enjoy a future of video looking so good.


The iXpand Flash Drive is available at Amazon.
