I have an advanced that I have had since June with hours and hours of video and I just noticed this problem pop up. I have vertical black lines in the very bright areas. This video is directly from the sd card. I have tried every possible setting and it doesn't make a difference. If I take a photo the lines are NOT there its just in the video. Running latest firmware and app. Overexposure warning is NOT turned on. I have searched and found other people with the same problem but no solution. Any help would be appreciated.
