Why shoot 8K if your viewers are on a headset or smartphone that can only render 4K? Insta360's CrystalView player solves this problem. It lets viewers watch 8K 360° video in full quality on Samsung Gear VR, Oculus Go, and mainstream iOS and Android phones. Any way you look at it CrystalView works by converting your footage into a specialty segmented sphere When a viewer plays it back in this format, their device will render exactly the area of the scene they're looking at – in full 8K quality – adapting in real time as they look around.
