I have a 8 minute video in My Moments from a flight I did. I used the cut tool and cut out a 15 second part of the flight that I would like to save to my Camera Roll on iOS. I can't figure out how. When I select the 15 second clip and click Next it puts it in the square at the bottom labeled 1. The clip is now cut in half and is only 6 seconds long and at the end of the clip it says my user name and DJI in the middle. What am I doing wrong?
