Nokia says Ozo is the most advanced VR filmmaking platform yet. It certainly looks amazing a spherical rig the size of a large cantaloupe, roughly 6 pounds, with eight optical image sensors spaced roughly an eye width apart. Audio is captured in three dimensions by eight microphones embedded in the camera, and the result is audio that helps to locate you in space. If you hear a dog barking behind you on in Ozo-produced VR, look behind you — you’ll see the dog. Ozo affixes to a standard tripod and outputs video in standard formats. You can watch Ozo video on a headset like Oculus’ or as a 3D video posted to a site like YouTube. The goal was to make a system that would integrate into filmmakers’ existing workflows, Nokia executives said, and not to trap them in proprietary file formats.
