The Following guideline is a good starting point for when to use each filter while filming with your Inspire 1, Phantom 3, or Solo. The goal of this chart is to reduce the camera’s shutter speed to 1/60th to give areal videos a smooth cinematic look, rather than a choppy high shutter speed look. A popular way of filming areal video is to have your shutter speed at double the frame rate. So if you are shooting 1080/60, then you want to try to achieve a 1/120th shutter speed. Or if filming 4K/30 or 24 you will want to be near 1/60th shutter speed.
