The video is only three minutes long, but each precious second is a feast for the eyes. The cinematography is top-notch, with some buttery-smooth slow-motion shots and a deliciously shallow depth of field. The delicate music in the background is also a treat, emphasising the feeling of quiet awe that washes over you during a truly exhilarating moment. The video’s creator, Bluearth Production, says it was shot using two Phantom Flex 4K cameras — one positioned at the top of the cliff, the other underwater, with both recording at a glorious 4K and 1,000 frames per second.
