I have no much experience in filming videos, but seen a lot of them and have some conclusions.
What you never should do – never ever shoot flying thing with only blue sky on background! Really, it causes nausea 🙂 There always should be earth or something static as a reference point, other way you can’t estimate speed, position and maneuvres.
Other evil is shaky hands. When you shoot small object moving fast it is difficult to track it on shaking or moving picture. Best of all is still picture or very smooth panning
