I have an extremely bad case of Rolling Shutter (Jello) and it is not caused by the props. I tested the camera without props and still get the Jello effect. By holding the Phantom and taking it through its range of motion while filming, I get the flight effect without the prop input. The effect is most noticeable in a Yaw maneuver. Less noticeable in altitude changes or forward and reverse motions. These effects are there in all flavors of 1080 as well as 4K. When I use any ND filter I solve the Jello problem but I don't necessarily care for the final effect on the colors (they look subdued---less vibrant). I have tested into and away from the sun as well as at 90 degrees left and right. I have a set of Rainbowers Professional Filters on the way, but I have some doubt that will help with the color issue (although I am sure they will solve a couple of other issues I am having with "stacking"). Any suggestions are appreciated.
