Clip is kinda short. If I go full screen on my laptop I see what appear to be artifacts then the picture suddenly hesitates and then sharpens. I don't think that's jello.

The only time I've seen wiggly video on my P3A is when I used cheap props. The gimbal does a fantastic job smoothing out the video. Here is a video my buddy made using his GoPro 4 camera that shows the jello effect:
