did anybody experirence this kind of footage? any help is much appreciated...

your image sensor might be degraded.  (maybe from bright light more or less burning it out)

GeeBax would know the exact cause.  Look for him.

Please contact Customer Support and let a technician evaluate your aircraft. You can start the process here: http://www.dji.com/service/repair

We have seen this before, it is a problem with the camera's sensor, it needs to go back to DJI for repair.
