How to Use a Swinging iPhone to Create a Low-Budget Bullet-Time Effect

Earlier this month a Swiss freeskier named Nicolas Vuignier posted an amazing YouTube video featuring bullet-time footage of a run down a snow-covered mountain. More impressive than the video, though, is the simple rig Vuignier designed and built to capture that footage with just a single iPhone.

The device, which Vuignier calls the Centriphone, took him about two years to design, prototype, build and perfect. In essence, it's a simple sled that gives the iPhone a set of wings to keep it stable in flight as it's soaring through the air around whoever is swinging it over their head.

It looks simple enough, but as Vuignier elaborates in this 'Making of' video, it was the subtlest of design tweaks and improvements, discovered through elaborate testing, that led to the rig's final design, and the amazing bullet-time footage that only requires a single operator.

Want to try it for yourself? Not only has Vuignier put two versions of the Centriphone up for pre-order on his site, one for the iPhone 6/6s, one for GoPro cameras, both available for about $54. He's also created an open source version of the Centriphone you can build yourself if you have access to a 3D printer.

Just keep in mind, you are accepting some level of risk when using your $1000 smartphone as a camera rig that's whipping around your head. The Centriphone's design promises to keep it held securely in place inside the rig, but should the handle that the four cables are tethered to slip out of your hand while you're careening down the side of a mountain, the survival of your device is in God's hands.

    Great, not only selfie sticks to watch out for now

    iPhone to the face in 5....4....3....2.....1.......

    It's interesting, for sure, but I wouldn't really call it bullet time since you're always going to have a rotating point of view. Would be great if there was some way of starting with a stable viewpoint and then moving to rotational. Still. Really cool idea / concept.

      Yeah I can't watch that spin for more than a few seconds!

    I don't see what part of swinging a $1000 non-waterproof phone round your head by some string in the snow is low budget but you could get some pretty cool gifs out of it!
