Think of drone video like a photographer thinks about a photograph. Get to a safe altitude, "frame your shot," then fly toward the most interesting thing in that shot. Don't make quick, radical "adjustments" left or right. Those jerks ruin good video. And, remember at least the three most basic drone shots: flying straight toward or away from something; flying sideways parallel with something and circling. Do those shots, edit out any bad parts and you'll always have a good, viewable video. Good luck. Keep at it.
