Hi there, Everyone: Just got my drone about 10 days ago. I shot 23 short test videos over a period of three different days and it looks like 8 of them are corrupted and unplayable. I have tried downloading several programs for "fixing" .mov files, and unfortunately none have been able to fix the files yet. The file sizes of the corrupted videos ranges from 37mb for the smallest to 310MB for the largest. I was recording at 1080p at 30fps I am using the micro SD card that came with the drone. I took a handful of photos (jpg format) and they all came out perfectly. This is a refurbished drone (refurbished by DJI) which I bought through B and H, who are pretty reputable. So if they say it was refreshed by DJI instead of some guy who fixes drones in his garage, I would tend to believe them. Everything seems fine about the drone except for the corrupted video files. I guess it could be a bad SD card, or could it be my phone, which is kind of a piece of junk? (Alcatel Fierce XL) I hadn't SD formatted the card first before shooting some video. I just formatted it now and am charging the batteries and will go out and shoot some video later today as well. Any thoughts on this???
