It's not often a camera gets a resolution upgrade purely through software, but GoPro appears to have managed just that. The company has released beta firmware that lets its Fusion VR camera capture 5.6K spherical video at 24 frames per second. That's not a huge bump over the original 5.2K, but it could still be noticeable in the confines of a VR helmet. GoPro manages the feat by capturing footage at 5.8K and stitching it together to produce the finished video.
