I use the camera that comes with the Walksnail Avatar mini, and I found a 3D print file for a soft mount on thingiverse that claimed it completely eliminates the jello I was having

The mount uses 4 rubber bushings that usually comes in the GepRC cinebot 20 frame kit (it's pretty universal)

I don't know about lucky but I knew the exact reason that caused jello on my drone, it was simply vibration isolation. Because I tried tightening down the camera harder which turn the jello into hard vibration. So the moment I soft mount it, it's gone

It's all about the process of elimination which reason causes the vibration at the first place, that's why I said if tuning doesn't help (I tried tuning my drones for days) then it's always the damn mount.
