Using Litchi, I created two identical flight patterns using waypoints and POI's as an experiment comparing the gimbal settings Focus POI and Interpolate. I varied both the waypoint and POI altitudes but both missions were identical. I was surprised to see no difference in camera angles between the two missions, but the one set to Focus POI caused the Mavic to stop, buck up and down, then continue a short distance and repeat. The bucking could have been a result of sudden stops and starts but there were no obstacles and that behavior did not occur in the Interpolate mission. Have any of you experienced that condition?
