This stunning 4K video was captured with an iPhone 6

The iPhone 6 twins are 4K capable, but so far the apps that claim to record video in such an ultra-sharp resolution have fallen a bit short of perfection. This clip, captured with the ProCam 2 app and a steady hand, is the best iPhone 6 4K video we've seen yet, and it's sitting on YouTube for you to enjoy.

Shot in a wooded area with a stream and plenty of detail to take in, the footage looks remarkably crisp thanks to a minimum of movement, which is important as the app is only capable of recording in 30fps or less. ProCam's app description notes that it doesn't actually capture in full 4K (3840x2160), but rather in 3264x1836 which is then upscaled approximately 17% to reach the desired resolution. Still, it's hard not to be impressed with the level of video clarity that can be achieved with your tiny little iPhone these days.

Note: At 4K resolution, the video can take a while to load from YouTube, regardless of your connection speed, so be patient.
