PetaPixel's running a piece about this 4K, 360-degree trailer that the company Immersive Video created for Samsung’s GearVR. "Utilizing sophisticated in-house camera gear," the article says, "the company takes us on an unforgettable 360° ride around the world."
The piece goes on to say, "To best experience this video, make sure you view it inside Chrome or in YouTube’s mobile app. You’ll be able to look around in the video using your mouse and keyboard (A/S/W/D), or by waving your phone around with the app. Be sure to increase the resolution of the video as well.
