I was using the Panasonic FZ2500 on a tripod on an outdoor shoot and the video was wobbly. I was shooting an interview with the subject seated, stabilization was turned off, used the manual focus mode and would touch the screen to focus on the subject's face. Tried switching to AFC for focus and that did not solve the problem. Never seen this wobble on the camera before, is it a malfunction from heat or does it have anything to do with settings?
