Vertical AI Video That Actually Holds Attention
Vertical is not landscape rotated. It has its own framing rules, its own pacing, and a brutal first second. Here is how to work with it.
A 9:16 frame is a corridor. You get one subject, one action, and almost no horizontal context, which is why landscape shots cropped to vertical always feel like something is missing. It is, and the viewer feels it in under a second. Native 9:16 output is available in the cinematic AI video generator.
Compose for the corridor
- One subject, centered or on a single third, never two competing focal points.
- Fill the vertical: heads near the top third, action in the middle band.
- Leave the bottom fifth clear for platform UI and captions.
- Use foreground depth instead of horizontal width to create scale.
The first second is the whole job
On a feed, your clip is competing with a thumb. Open on motion already in progress, at the closest shot size you can justify. No establishing wide, no fade-in, no logo. The move that would normally end your shot should often start it.
Close-up, 9:16 vertical. A hand slams a rain-slicked metal door shut, water sheeting off the surface. Camera: locked off at hand height, subject already in motion on frame one. Light: single cold overhead practical. No slow motion, no fade in.
Motion on frame one, one subject, bottom fifth clear.
Pacing: shorter than you think
Vertical beats land between one and three seconds. Anything longer needs a reason, a face doing something, or an escalation. If nothing changes inside a beat, cut it in half and generate the next one. For the move inside each beat, see camera movement in AI video.
Sound is not optional
Most vertical viewing has sound on, and phone speakers flatten everything below about 200Hz. Favor transient detail, impacts, cloth, footsteps, breath, over low rumble, because that is what survives the speaker.
