Do you ever record with your phone? If so, there is probably a chance that you film vertically. By this I mean holding your phone the vertical or up and down way when you film the video. Not only are the thick black pillarbox bars on either side of the video extremely annoying, but the human eyes are designed to see the world in widescreen. That's why they sit side-by-side, and not on top of each other. And sure, sometimes it's just easier to hold your phone vertically in one hand to capture a scene. But if you take the extra second to turn it sideways and use two hands, you'll capture loads more resolution and the footage won't look like you're riding out an earthquake.
