I can't seem to work out how to change the video size to 4K at 30fps. I have tried both the android and apple versions of the pilot app and it is not an option. On 3840x2160 it only lists 24 and 25fps. In the specs it says is is capable of UHD (4K): 4096x2160p24/25, 3840x2160p24/25/30. Also I've seen sample videos on YouTube saying there 4K 30fps. Can you help?
