I suggest you upload your flight log to
Healthy drones, or msinger's
flight log reader and see what you can learn from the data. Share the link with us.
After thinking about your video, if you had OA enabled while flying it shouldn't have allowed you to get that close to the object in the first place, since you were going so slow. My P4 stops way before that, so it appears you didn't have OA enabled when you were flying, correct? If that's the case, I have learned something new about RTH OA, it lets the craft get closer to an object than OA would normally allow while flying.
So, tip #5, always use OA when doing POI shots of an object like that. It will keep you a safe distance away.
