I bought the ND filters dataway is selling for a few bucks http://www.phantompilots.com/thread...-weight-updated-with-comparison-photos.42196/ . My videos had been jerky. I put the filter in and the next video came out silky smooth. I have to figure out which setting the filter caused to change in the auto mode that it is in. Oh, and btw, the color was beautiful on the video.
