I was doing a lot of video recording recently and noticed that what I see on the iPad screen is not a true representation of what gets recorded. On each side of the recorded video there is more space being recorded than shows on my iPad screen at the time of recording. For instance, I was recording video of someone sitting in front of a black screen. I was tight enough that on the iPad you could see the subject and black background. When I viewed the video later I realized that the white walls on either side of the black screen made it into the video. Any knowledge on this matter or any tips?
