I calculated the magnification is about 350% to 400% at the camp site.
I did the same magnification on my very only 1 test video and it seems that , my Solo is a bit better than Min-KS , its is a bit less vibration. I am assuming both are videos are at very low ambient wind speed.
However to eliminate vibration a 100% on a drone's video, while props spinning and drone is hoovering and video FOV is static and at 350%-400% magnification, that I would say is near impossible. In any video, a static scenery shot is almost always 5 seconds only and slow pan would be next. Its boring to watch static scenery as video, as photo it is nice. Slow panning takes away any vibrations as motion blur starts to play or "cover-up", more so when ND filter applied and we can keep shutter speed within the 180 degrees rule.
I don't have enough experience hours on drone gimbal, but I have decent experience on handheld
3 axis gimbal.
I agree with Ian, there is no such thing as a drone not sending out vibration energy at that kind of propeller spin speed and 4 of them. Gimbals do cancel vibration out but can never do it at 100% or at super minute angle adjustment.
On my handheld gimbals repetetive similar vibration it can cancel out well, but very sudden ones, not so. Example if I sit on a motorbike as a passenger and hold the gimbal, the suspension play causing vibration is cancelled out by the gimbal, but it can not cancel out intermittent sudden twitch from my hand.
For me props and motor vibration is one thing, but hoovering stability is another as it generate those sudden fast correction ( wind dependent ) which is not as constant as props or motor vibration. So I would want to avoid prolonged static shots.
Min-KS, I am sure there is some fine tuning you can do to improve the vibration, there seems to be a bit of room for improvement. Why don't u download the android vibrations apps and at least try to find which motor/props is generating more vibration than the other and start troubleshooting from there. You must try to maintain same RPM as when you hoover as motor/s and prop/s combination has its own certain un-sweet speed/rpm called critical speed.
Critical speed - Wikipedia, the free encyclopedia
Actually if you are a decently good flyer, all u need is a light type tachometer which read prop speed ( RPM ) using those 3m reflective tape and measure what RPM is the hoover RPM with the weight of the said camera you are using. Once you get that speed, get a 2 friends to help you, 1 guy hold down the drone at the said propeller RPM with if possible 1 finger only to reduce absorbing the vibration, the other guy read the light type tachometer and play with the throttle to try to mimic the hoovering RPM. Don't read vibration at the props where the reflective tape is placed on, as no matter how light the tape is, it may contribute to added vibration. This is just a suggestion to narrow down the source of vibration.
In a craft with more than 1 motors, different load on 1 motor may cause overall vibration.
On a propeller, due to some deformation or defect or fatigue, if any blade is having/carrying different load, vibration will also occur. Balancing a prop is about weight finding, it can not tell blade loading.
I had a bit of marine propulsion background, assisting one of my Boss, so I learn a thing or two . On a 4 blades marine propeller, all we need is 1 small ding on the props and the load per blade is thrown off, heavy vibration can occur, regardless that the static balancing read good. Since water is approx1,000 times more dense than air at sea level, any small ding effecting water flow on the blade and hence propeller loading, will effect a great deal. On a drone air props, it may not be the that severe but it will effect to some degree, nevertheless, no free lunch.
Good luck.
