Vertical by default: how the shape of the phone changed what we film

For a long time, filming meant turning the device on its side: the lying-down rectangle was the shape of the image, in cinema as on television. Then the camera became the phone, and a phone is held upright, in one hand, often while walking. Nobody decided video would go vertical; it was simply the position the object was already in. Apps followed, screens filled up with standing rectangles, and turning the device sideways became the exception rather than the rule.

A frame cut for people

The vertical format isn't neutral: it matches the shape of a standing person. A face, a torso, someone talking to camera all fit perfectly, with no empty space around them. It's a tight frame, one that brings you closer, and it gives all these videos their air of conversation rather than spectacle. It also matches the way we watch them: at arm's length, right up close to the face, a single video filling the whole screen. What used to count as bad framing has become a grammar in its own right, with its own codes and habits.

What vertical leaves outside

The price shows up as soon as you film something other than a person. A landscape, a room, a row of friends, a scene viewed from a distance: all of it spills out of the frame, leaving only a narrow strip in the middle. Vertical tells you very well who is speaking, and far less well where you are and what's going on around. Context, which is often the whole point of a video shot on the spot, gets cut off left and right. That's also why some vertical videos feel filmed too close, without your being able to say why.

Choosing your frame instead of putting up with it

The good habit fits into one question asked before you press record: am I filming someone, or am I filming somewhere? A person talking, a demonstration, a gesture seen up close all stay perfect in vertical. A setting, a view, a wide scene deserve turning the phone sideways, even if the video then displays smaller. There's a very practical reason too: a video shot horizontally can be cropped to vertical, while the reverse doesn't work - the missing edge can't be reinvented. In other words, vertical is a good default setting, not an obligation.
