Last time I was flying I experienced some strange image vibration in the recording... In the previous flight with another battery in te same place minutes before it didn't happened. I haven't had opportunity of flying after, son i can't see if it continues. I used later the camera on Osmo without issues. It was a little windy but no too much. It seems to vibrate somtimes when the aircraft stops or begins movement.. I have revised camera mounting plate and didn´t nocticed something. Is an I1 v1 with X3.
The video works now.
Did you try to calibrate the IMU and the gimbal? If that didn't work for you, you'd better return your unit for a check. It seems there's something wrong with the hardware.
