I purchased the a6000 a while back and used it for a few. Before I returned it I noticed that some bars on the video feature were under exposed. There were about 3 to 4 bars. I decided to record the video and put it in my lap top just to make sure if it was the cameras screen or something, But as soon as I saw the footage on the computer the bars were in there as well. I returned the camera because I ended up buying the a6500 anyways. Since its a new camera and newer model i forgot about the issue. Later down the road of using the camera I noticed the exact same problem come up on this camera. It is very odd I have done some research and looked for similar situations as mine but so far nothing. Basically I get about 4 horizontal bars that go across the frame of my video that look underexposed. Please take a look at this frame I captured at an event. If you look at the screen shots carefully. You can see the bars are in the exact same position.
