Shoot Landscape!
Nothing distracts a viewer from focusing on great footage like having two black vertical bars along both sides of your video. To avoid this issue, make sure to use landscape orientation and not portrait orientation while recording.
Not only does landscape make your video seem more aesthetically pleasing in general, it will also make it more enjoyable to watch when viewed on a widescreen or television. Plus, you'll capture more in the actual video.
So just remember: The record button should be on your right (the side that your charging port is located). ***
