But, what if you just put your camera on the tripod faced downwards, set all the settings you need, and turn off camera. And then, you turn on and just start recording with the remote without even touching the camera. In this case, all sensors should be at "zero position", I suppose. Or, what if you turn OIS permanently off, turn camera off then on, and start recording with setting off. Or the same scenario with manual focus. In addition, I can imagine that OIS should be turned off in horizontal position and then it should face downwards. I have some other ideas, too
What I am sure of, if it can be jitter-free sometimes, this must be a software (firmware) issue. I think that these sensors or magnets may remain in an "always calibrating" state but can be reset with a sequence of settings that you accidentally applied sometimes.
I am just guessing, but it's worth a try. And, I have no camera, so some of you should play with this
