Unfortunately I cannot look at your video clip at present as my editing computer is down, but I got a poor look at it and I think I can see some jello. Jello only has one cause, and temperature is not a factor, it is vibration of the camera. If, in your test, the motors are not running, then something else must be causing the camera to vibrate.
I wonder if when it is sitting on the bench, when you lightly touch the camera, can you feel any vibration? I am thinking that perhaps the fan in the body of the aircraft might be causing vibration? Another potential cause is the gimbal itself, if the gains are too high, then it can vibrate. There is a thread where a user fixed his vibration in this manner: http://forum.dji.com/thread-39365-1-1.html
And if the gains are causing the vibration, to be honest, something is wrong with gimbal. Those settings are there so you can customize your drone according to your flying style and filming/photographing needs, not to eliminate gimbal vibrations. I would simply not accept this as a fix. If these settings are causing problems, eliminate those settings or fix them. It is like you would buy a phone with a menu item that would set phone on fire if clicked and the fix would be a big warning not to touch it, even tho some user would need to access that menu.
But for the record, while I did changed ghimbal pitch roll settings (as I think it was too violent and too mechanic w/o dampening) and changed all EXP settings to 0.4, never touched any GAIN settings. All were factory default at 100. I own a lot of radiocontrols, including a Futaba 14MZ, and none would force you do something like that, it would be ridiculous. I have at least 300 hours of radiocontrol flights and more than 1000 of real life piloting.
And I just watched first video tests after getting Phantom 4 Pro out of the box when I did not changed anything, and clearly that jello is there. Something is definitely defective there. I watched tens of Phantom 4 Pro videos and none show something like that. There is no point to fight a war that is not mine. Clearly DJI rushed a bit the Pro production and I think they knew and assumed this could happen. Hopefully they won't go the path Karma or Note 7 went for the sake of more products and more profits.
DJI still is an awesome company and quick technology changes make such things inerent, but I do hope they knew what they are doing and planned for all the returns. And a few of us will have some extra hassle solving them, but if they are active and resolve problems quick and to customer satisfaction, all will be ok in the long term.
