Apparently, YouTube supports 8k 360-degree videos.
Someone uploaded the Insta360 Pro sample videos to YouTube and they were saved as 8k! I’m not sure how long they’ll stay there because it’s a violation of Insta360’s copyright but anyhow I’m glad YouTube enables sharing of 8k 360 videos.
BTW, even my VR-ready PC with a GTX 1060 6GB had a hard time playing the video at 8k.
