It follows the person
Subject tracking follows the speaker, so somebody who moves does not walk out of frame halfway through the clip.
16:9 turned into 9:16 by following the face and cutting at the scene changes — not by dropping a fixed crop box over the middle and hoping.
Subject tracking follows the speaker, so somebody who moves does not walk out of frame halfway through the clip.
Scene-change detection means the crop moves at the edit point, not sliding across the middle of a take.
The landscape original stays untouched; the vertical version is another output of the same job.
Almost nothing worth watching is framed dead centre. Interviews sit the subject to one side, two-handers put nobody in the middle, and any camera move leaves a static crop pointing at a wall.
Following the subject is the difference between a vertical cut that looks deliberate and one that looks like a mistake nobody checked.
One recording now has to become a landscape upload, a vertical short and usually a square. Doing that by hand for every clip is the reason most people stop bothering with the vertical cut.
