Vertical video framing starts with subtraction. The tall rectangle holds one subject well and crowds everything else, so the smartest move is to decide what gets cut before you decide what gets seen.
Most framing problems on a phone come from trying to include too much. A wide shot that felt generous in landscape becomes a thin strip of ground and sky once the screen turns tall.
The strongest vertical shots center on a single person, face, or object. Two people means one of them lives at the edge of the frame, half present. I frame for the person who is speaking and let the other lean in when their turn comes.
Distance matters more than lens. A medium close up from about arm's length fills tall space with a face and shoulders. Step back and the subject floats like a postage stamp in a doorway.
If you cannot name the one thing the shot is about, the frame will decide for you, and it usually decides badly.
The top of a vertical frame is prime real estate and often wasted on ceiling or sky. I raise the camera to eye level and tilt so the subject's head sits near the upper third, with room above for a caption if I need one.
The bottom is where hands and props belong. A product held at chest height lands in the lower half, which is exactly where a viewer's eye drifts after reading a line of text. Framing for those two zones makes captions easier later.
A monitor tells you the composition. A phone tells you the truth. I always review a framing test on the same handset a viewer would hold, because the crop and the glare change what the shot feels like.
Get in the habit of shooting ten seconds, then watching it back on the phone. The fix takes a minute, and the alternative is a finished video that never quite fits.
Designing vertical video for a phone screen starts with the frame, not the edit. Plan the shots and the text long before you sit down to cut anything.
Text on a vertical video has to sit where a thumb and a caption bar never cover it. These placement rules keep the words readable on a small screen.
