Hello!
I bought these propellers
http://store.dji.com/product/9450-carbon-fiber-self-tightening-rotor-black-white-stripesA propeller with a black mark is the butterfly effect (curve). (one blade is higher than the other blade)

I think making a video camera GOPRO resolution 4k 30p I get blurred images (video jelly)

Use an ND filter and record in a higher frame rate ie 1080 50fps

Would not it be a loss of quality images?
So you can apply the usual glass with sunglasses
