B-roll
Also called: broll, supplemental footage
Secondary footage cut over the main talking-head shot to illustrate, add energy, and hold attention.
B-roll is any supplemental footage layered over your primary (A-roll) shot — stock clips, screen recordings, product shots, or related video. In short-form it does double duty: it visually explains what's being said and it adds motion that resets the viewer's attention every few seconds.
Well-placed b-roll is one of the cheapest ways to lift retention on a talking-head clip. The art is relevance and timing: the cutaway should match the exact moment it references, then return to the speaker before it overstays.
