A friend lost his P4P into the ocean while shooting some videos. He is not technical so I offered to help him pull the low resolution videos from his controller. He has the Phantom 4 Pro PLUS model transmitter with the display built in. I thought it would be simple to get the videos from the onboard SD card but they are not on the SD. I can watch them from the controller's display so I know they are in its internal memory. But there is no copy or move function available when I view the videos. Only DELETE! How do I get them?
