Dave: The arbitrary limitation of 99 waypoints kills the DJI solution. This limit is both impractical and nonsensical - it will have to be lifted soon. However, you can still take advantage of the log-spiral curved flight lines (in their original form with only a few waypoints). Google “gently curved, convergent, non-traditional drone flight paths” and take advantage of the constant tangent angle property of the curve to do away with (minimize) camera movements - see first example below. The second example if for a fixed-wing drone - complete with turn-out loops where needed. The third example is for a multi-rotor drone.
