I have noticed using a second RC for controlling the camera can cause this effect and virtually prevent downloading images to a connected iPad. Also wearing a harness and bending forward so the aerials do not 'aim' correctly has a similar effect. I have got used to the screen going black momentarily, the difference here in your video is the refresh time from the black screen back to image it's quite slow. There may be another issue.
