Nokia has just revealed a new camera for filmmakers called OZO that can capture virtual reality videos. But unlike similar devices from GoPro and Samsung unveiled in the past months, it's not a flattened circle with cameras but a spherical ball-like device with shutters all over it. It has eight shutter sensors in all to capture 360-degree videos and eight integrated microphones. What users might find advantageous is its capability to show them what it's shooting in real time through a VR headset. It can also churn out a low-resolution version of the footage it shot within just a few minutes if filmmakers want to see it again or to show it to someone else. Videos captured through similar cameras usually have to be stitched together during processing before you can see them, and that takes a lot of time.
