I searched and couldn't quite find my exact problem (or maybe just not using the right search words). I have a P4 and am using the SD card that came with the drone as well as a SanDisk Ultra 32 GB card. For both, they've been formatted in the drone. And both just record.... nothing. I mean, there's a file there on the SD card, I can see how long the video is and play it, but when I try looking at the video on my computer using a card reader I've used before that works, all I see if a black screen. When I tried loading the video into Movie Maker it says the file is corrupt. When I'm recording on the actual drone I see the video fine, and the video is saved on playback on my iPad. So it recorded just fine. I can see the video if I load it through my Apple iCloud account. So not all is lost since I can still access the videos, but I would really, really like them to also be saved on the SD card. Any idea what I'm doing wrong?
