Lucas Matney, TechCrunch:
Full 1080p is fine for spherical photos, but it’s actually a pretty low resolution for video when all those pixels are stretched over a 360-sphere. Today, Facebook is bringing 4K support to Live 360, and, along with it, support for viewing broadcasts in the Facebook 360 app on Gear VR.
360 video is arguably more of a novelty than full VR at this point. Sure, 360 video is more widely available, and watchable on a standard phone or computer screen without a headset. But when’s the last time you heard anybody get excited about a 360 video? At least enthusiasts keep coming back for more VR content.
