B-roll
B-roll is supporting footage that plays over or between the main shot, such as product close-ups, hands using the product or scenery.
In short-form ads, cutting to B-roll every two or three seconds keeps the picture moving while the voiceover carries the message. It is also an easy way to show the product without a full demo.
