Safe zones are the parts of a vertical video that platform buttons and captions never touch. Every app draws its own controls over your footage, so the usable area is smaller than the export suggests.
Ignore safe zones and a follower count covers your product name, or a caption bar eats your best line. The clip still plays, but the viewer misses the point you paid to make.
When a video plays full screen on a phone, the platform overlays a strip of controls. Sometimes it is a username and a music note at the bottom. Sometimes it is a caption toggle or a shop tag. Those layers move, and none of them ask permission.
The safe move is to treat the outer edge of the frame as borrowed space. Design the important content for the center and let the edges hold sky, wall, or movement that can be covered without loss.
I sketch a rectangle inside the frame and keep faces, hands, products, and text inside it. Anything that drifts toward the edge is a candidate to be clipped by a button. A quick preview in the app confirms where the damage would land.
The frame you export is not the frame the viewer sees. The app always keeps a little for itself.
I keep an overlay on my editing timeline that marks the danger areas. New projects start with it switched on. After a while the habit sticks and I frame for the safe zone without thinking, which is the point.
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.
Vertical video framing for a tall screen is mostly about what you leave out. Here is how to choose a subject, a distance, and a background that holds up.
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.
