Good news! You just shot what might be the world’s funniest video ever. You’re going to be a friggin’ YouTube sensation. You’re totally going to hang out with Ellen. Bad news: you shot the video in portrait mode. Whoops! Now the entire Internet thinks you’re dumb. Horizon is an iOS app that auto-magically ensures that your videos are shot in landscape (read: widescreen) mode, no matter how you’re actually holding the phone. Even if you rotate the phone while shooting, the video’s orientation stays the same. Wondering why the whole portrait/landscape thing matters? Others have explained it more aptly than I probably can, but in a nutshell: pretty much every damn screen we watch video on these days is meant for widescreen/landscape content. When you shoot videos in portrait mode, you end up with big ol’ ugly black bars on the sides that take up an overwhelming majority of the screen.
