I need some help. I recently purchased a P4P. Not my first phantom. I took it out to shoot some video and the video got jerky and had lines running through it. It was very hesitant. I have made sure that everything is updated, the signal strength is ok. When I switch back to photo it looks ok stationary but gets screwy when I move the drone. Brand new sd card. Scandisk 64 gb. I was able to get this picture in photo mode after it had been in video mode. I am beginning to suspect the cable. Any help is greatly appreciated.
