How to turn on 4K video recording on the iPhone 6s and 6s Plus
Eye on Apple

The iPhone 6s and 6s Plus are the first iPhones to offer the ability to record video in 4K. If you’ve ever seen a 4K video then you know how amazing they look compared to 1080P and other lower resolutions. Unfortunately, 4K video recording is not enabled by default on the iPhone 6s and 6s Plus.
No worries, I’ll show you how to enable 4K video in this tip.
How to enable 4K video recording on the iPhone 6s and 6s Plus
Just follow these simple steps to turn on 4K video recording on the iPhone 6s and 6s Plus:
1. Go to Settings.
2. Go to Photos and Camera.
3. Scroll down and go to the Camera section.
4. Tap on the Record Video option and then choose 4K at 30 FPS.
Now when you record a video, it will be in 4K instead of 1080P.
4K vs. 1080P on the iPhone 6s and 6s Plus
Now, for the most part, I’d argue that 4K is a better option for recording video on the iPhone 6s. However, you should note that recording video at 4K also means being restricted to 30 frames per second. If you go with 1080P, on the other hand, you can record at 60 frames per second.
Which one is better? Well, like most things, beauty is in the eye of the beholder. So I recommend trying both settings and then viewing the results before making a decision. If the 4K video looks better to you than use that instead of 1080P.
If you still aren’t sure then you might want to check out Macworld’s excellent guide to recording video on the iPhone 6s. It covers the differences between 4K and 1080P, and offers some advice on when to use each setting on the iPhone 6s:
So, what exactly is 4K video, and why is it different to 1080p HD video? In its simplest form, true 4K video is around four times larger than standard 1080p HD video, with a native resolution of 4096×2160 compared to 1920×1080. With regards to 4K video recording on the iPhone 6s and 6s Plus, 4K video isn’t quite native 4K – it’s classed as ‘Ultra High Definition’ much like our ‘4K UHD’ TVs, as it has a slightly lower resolution of 3840×2160, although with this being said there isn’t any difference to the naked eye.
So, when do you use 1080p and when do you use 4K? Ultimately, it’s down to your personal preference and, to some extent, the amount of storage your iPhone has. Earlier we discussed frame rate, and how you can record at a higher frame rate at 1080p than at 4K, which is an important factor to consider when deciding which format to use. Ideally, to get the best possible video quality from 4K @ 30fps, your subject/location should be well lit, feature a lot of detail and slow/no movement.
On the flip side, if you want to record something fast-paced like a race or a dance routine, your best bet is to use 1080p at 60fps. The higher frame rate will provide a much smoother video, allowing you to see more of what is being recorded and, as mentioned earlier, will provide the illusion of a higher quality, professional video. 1080p is also advised for low light conditions, as recording at 4K has more pixels and in turn, smaller diodes (which effects low-light performance).
Whichever option you choose, it’s clear that the iPhone 6s is Apple’s best phone yet for recording video…for now. I have no doubt that the iPhone 7 will offer 4K video recording at 60 frames per second. Until then though you’ll have to choose carefully between 4K and 1080P when you record your videos.
