When the iPhone 6s and 6s Plus are announced it is widely rumored that they will be able to shoot 4K video. But there are already a few apps out there that offer 4K video capture on the iPhone 6 and iPhone 6 Plus.
Though the iPhone 6 is not able to natively capture 4K video that hasn’t stopped app developers working out how to get the camera to record 4K video. The solution is to have the camera shoot twenty-five 8-million-pixel photos in a second whilst recording sound, and then merge it all together and save it as a video clip.
There is a slight catch. The iPhone 6 camera resolution (3264 x 2448) falls slightly short of 4K (4096 x2160 pixels) and UHD (3840 x 2160 pixels), so to get these higher 4k resolutions the apps upscale the footage by around 18%.
The quality of the footage can vary a bit from app to app, but if you are after a taster as to what 4K footage will look like then this is a great way to get started. And you will be surprised with how good the footage can look, especially as most of the apps allow a decent amount of exposure control.
The footage is usually kept within the app. If you save it to the Camera Roll it is downsized to 1080 so that it plays without any problems. However, the apps we have tried allow you to save the footage to your computer via Dropbox or iTunes transfer.
One word of warning though – 4k video shot on the iPhone 6 can take up a lot of space, roughly 30MB per second. Also, as the camera is using the whole of the sensor to capture footage, the iPhone 6 will be unable to use the digital stabilisation, although the iPhone 6+ optical stabilisation should still work.
So, of the apps available, we’d recommend ProCam 2, which is a great camera app and also good for standard HD video capture. See our sample 4K footage above, which was shot with ProCam 2. It costs £2.49, plus a £3.99 in-app purchase for 4K video.
Here are some other apps we’d recommend trying:
4K Recorder £4.99
Ultrakam 4K £7.99
And if you feel like splashing the cash then there is also VizzyWig 8HD which will set you back an incredible £79.99
