I purchased the mini about two months ago, and finally had to send it back to DJI in California. I live in Ontario Canada. Anyway, ever since I had the mini from day one, a lot of the mp4 video files are corrupt. Usually the very first video on a newly formatted micro sd card is fine, but none are any larger than about 4gigs, the rest of the files are corrupt or at least cannot be read. They are saved as mp4, all of them but most cannot be read. It usually only happens in flight. If I start the video while the props haven't started turning, the video is fine, then I stop the video and restart video, fine again, and so on, but as soon as the bird takes off, the second and subsequet videos are corrupted or cannot be read. Does it have anything to do with the fat 32? So anyway, at DJI they tested it and they weren't able to generate any corrupt mp4 files. I've tried three different micro sd cards, all ones that DJI recommends, my cards are fine, samsung and sandisk, latest greatest 32 gig all three cards contain corrupt vids.. So anyway DJI sent back the mini but I bet they didn't test it in flight because they had me return it to them without the props.. any ideas what it could be or how I can recover or repair the corrupt mp4 files? I also have a Phantom 3Pro ..never any issues with that.Thanks so much. Frank
