I was recording video with the Phantom 2 Vision and the battery must have died because it flew back to a previous spot I was filming at. For some reason it didn't come back to the spot I was in. Now that I'm back at the studio (in another state) I see video file there but it won't play. The file that was filmed previously plays fine. I read that it might be because it didn't finalize. I may have shut off the drone before it finalized or the battery died. I know when I tried to stop recording on the Samsung Note it said connection was broken or lost so I wasn't able to stop recording that way. I really need the footage it shows over 900 megs and it's an MP4 but it won't play.
