01Vertical brings us closer
A 9:16 frame suits faces, vertical motion and a person's relationship with one object. Place essential action near the center and leave room for captions and platform controls. Vertical filmmaking is more than cropping the middle of a horizontal shot; it calls for less scattered information from the start.
02Widescreen builds a world
A 16:9 frame makes relationships with an environment legible: a huge city and a small traveler, or two people separated by a silent table. Build foreground, middle ground and background so the eye has a path. A square frame works well for a central object or quiet symmetry.
03Let sound do one useful thing
Generated clips may include model-produced audio, but clear dialogue, precise timing and multilingual captions still deserve an editing check. Give sound one job: establish a place, signal a change or contrast with silence. Listen with headphones and then watch muted to check whether the visual story still works.
