I shot a video that was wide, so I held the camera sideways. Now when I play it back, either holding the camera sideways (landscspe) or vertical (portrait), the image is sideways. So I hold it vertical as normal, the image is on it's side. If I switch and hold the phone sideways, the image rotates 90 degrees and is still on its side.
I tested it just now, holding the camera upright, left side, right side, or upside down, and the images are upright. But the video I shot this afternoon holding the camera sideways is displayed sideways.
