A drone does not bank into a turn like a traditional aircraft, it remains level as it spins in the air to change direction. Even if the drone banks slightly to counteract the wind the camera gimbal keeps the video level.
The resulting video from the drone seems flat to me, a sense of something wrong, I expect a little roll while turning. I find myself struggling with the resulting imagery, what do I do with this?
It is not only aircraft that bank into a hard turn, even an automobile does this on a properly designed roadway. If the car does not truly bank, we passengers naturally lean into the turn to counteract the centrifugal force. We expect to lean into a turn, while a drone does not.
How do I restore that roll in the drone video?
