Over the weekend I shot some video at 60fps/1080. At 2m19s in, the video stopped, and then it captured another clip for 24s and stopped. The only other capture I did that day was also 2m19s, but in that case I did switch from video to still. I don't recall touching the phone during the first shoot, but was quite upset to see half my footage missing. I know later DJI Go releases removed the 60fps from the standard (I'm on the last one with it). Does anyone know if it was a stability issue like this? Usually I don't bother with the 60fps, but wanted it for the ocean shots. I am using the SD card that came with the bird. I will try formatting it from the Go app next time I go to use it as I read in other threads - was more curious about the 60fps though. If there is a bug like this, then I may as well upgrade.
