Sound design is choosing, creating and arranging what viewers hear to support what happens in a video. It can establish a location, make an action feel physical, draw attention to a detail or shape the mood of a sequence.
A product landing on a table might need a small contact sound. A street scene might need distant traffic. A reveal might work better with a brief build-up—or a pause before it happens. The right choice depends on what you want the audience to notice and feel.
The invideo agent inside invideo Editor can help turn that direction into sounds arranged on an editable timeline. You can ask it to build the first pass, then change the choices and timing through conversation or manual editing.
