You can not only take great photos with the iPhone X, but great videos, as well. The Apple smartphone lets you shoot high-resolution video up to 4K, with over 8 million pixels.
To enable it, go to Settings › Camera, then tap Record Video and select 4K. At 3,840-by-2,160 pixels, 4K has four times the pixels of 1080p (1,920-by-1,080 pixels).
