Do Not Hold the Picture Button Down on iPhone for Videos, You'll Regret It

I learned a thing today, maybe helpful to some: you can take a video on your iPhone by holding the camera button, it’ll switch to a video - this I knew. The problem is it shoots said video in the 4:3 aspect ratio which is terrible. This is the same aspect ratio your TV used in the 90's, it's almost a square.

Lesson learned, always switch to the explicit video mode because it’ll shoot in the proper 16:9 ratio for horizontal videos. The "hold the camera button" is intended for quick videos that are vertical, not a “shortcut” to start a horizontal video. I’m realizing that I’ve mis-shot many previous videos this way out of convenience without realizing the impact it was having and I’m now very sad.
