A firmware and app update for the Qoocam 8K (reviewed here) added 4K live streaming and 8K mobile editing, which Kandao calls Express Edit. Here’s a demo and tutorial.
Qoocam 8K is the most affordable 8K 360 camera, with a video and photo resolution of 7680 x 3840. In my tests, it has proven to have the best detail for 360 videos among 360 cameras up to around $1200. Now it has become the first 360 camera to have an 8K mobile workflow.
