lower and slower

when I try to set the max resolution to 0,4 cm/px, map pilot often says "aircraft cannot fly slow enough ... "

- is there a way to slow down the speed during the mission in order to reduce the motion blur at a given shutterspeed and given overlap (70%)?

I dont understand the dependency between minimalspeed and overlap.

There are limits to how slow you can fly using DJI aircraft. The slowest allowable speed is 2 meters per second. You get the warning in your screenshot if Map Pilot cannot set the speed below that limit. This is all based on your selected camera write speed, altitude and overlap setting.
