When you say that the video was taken just after the camera was "freshly cleaned".  That may mean the sensor was clean, but it does not mean that there were not dust particles in the camera, and if there are, 5400 mirror flaps are going to move them around, and some of them will wind up on the sensor.  I'm not saying you don't have a potential issue, but I'm confident that if you do it's not the same issue experienced on the D600.  Just curious, have you tried using a bulb blower and taken before and after dust reference shots?  Spots from oil or other wet causes will almost always persist in before and after shots, but so will things like sticky pollen particles, which you're bound to get if you shoot outdoors.  Most plain dust will either be removed or at least move when using a bulb blower, so check some before/after shots with that and it will at least help you a bit with the diagnosis.  But as a fellow Jersey shooter I can attest to the fact that there's plenty of particles around to sneak into your gear, and if I'm shooting out in the woods or in fields I'm dealing with pollen half the year, and then cold weather induced ion-charged dust from crumbling leaves and breaking stems and seed pods the rest of the year.  I'm constantly blowing my sensor clean and I've done 3 sensor cleanings on my D600 and 2 on my D800 this year alone.  Part of the price of doing business.If you are looking to do your own cleanings I'd suggest waiting until a couple of us get our sensor gel sticks, which should be delivered in the next week or so.  I've used a wet cleaner previously which works great but the wipes run about $3-4 each and a cleaning often requires more than 1.  This holds promise to be a much easier and cost effective solution.</blockquote>
