The more P4 videos I watch that are being released on youtube and such. I'm not impressed with the results at all. Too much, jello, too much rolling shutter. The camera/gimbal itself is shaking a lot worse than my P3P. Supposedly it has a more stabilized gimbal. I just can see how 2 mounts on a gimbal is more secure. It seems more like a lock down mount rather than freely moving around. If you don't believe me look at the videos on youtube yourself.
