GH4 realizes automatic follow-up focusing when shooting video, and the focus is always on people from far and near. I switched to AFC and tracked the focus. Before shooting is not pressed, the focus always follows the person, and after shooting is pressed, although the tracking frame still follows the person, the focus is always set at the beginning.

GH4 users. Video shooter, when I use the electronic stabilizer, because of the balance problem, my position will cause an axis to block the viewfinder, resulting in no picture on the display screen. How to set it to solve this problem? I don't want the viewfinder screen to turn black.
