You're in the U.K. so your sun may not be as bright as others are used to. You *do* get *some* sunshine once in a while don't you? Just kidding!
One of the other posters in this thread is in the U.S. I don't know where he/she is physically located, but, if it's in an area where they can experience bright or very bright sunlight, all that light is often the culprit of the dreaded jello effect.
You can adjust your ISO only down to 100 - you cannot go any lower than that. On a really bright day (and even on not-so-bright days) ISO 100 is simply not nearly low enough - too much light gets to the camera sensor, trying to "blow out" the exposure. The auto camera system compensates for so much light by speeding up the shutter, i.e., trying to keep all that light down to a dull roar. Then your shutter speed suddenly becomes a big problem.
The shutter opens and closes so rapidly that it barely has enough time to capture the information it needs to capture, then it slams shut (figuratively speaking) and starts another sequence and you suddenly experience a "shifting" of the image because it can't quite "catch up." This "shifting" effect from frame to frame creates what everyone now identifies as "the jello effect." It looks like all your images (frames) are shimmering as if they were pictures painted on the flat surfaces of jello.
One other problem. You can pan (rotate on the camera/Phantom axis) faster than you can fly - in *any* direction. Now, with a very fast shutter speed, if you're panning, you'll create this horrible "choppy" effect. On the plus side, if you needed to capture a still from that piece of your video, a very fast shutter speed will stop the action. But, all other things being equal, you'll get this "...I think I'm going to throw up...." reaction from viewers (and you as well!) reaction to that fast panning motion.
Put some sunglasses on your camera (ND filters) and you'll regain better control over your choice of ISO, slow the shutter speed down and even the panning starts to get smoother.
The bad news in all this? Even with that, you can accomplish terrific improvement with the panning/turning by sloooooowing it down as much as you can stand it. Eventually, we've been promised a feature known as POI (Point of Interest). POI lets you "target" something and fly by/around it, keeping it constantly in the camera frame. With a decent amount of practice, you can learn to do fly-bys and circling objects with POI. From what I've seen, though, the POI can be very impressive!
Enjoy!
