What Is B-Roll?

B-roll is supplemental video footage used to support the main content in a video. It's often layered over primary footage, also called A-roll, to add visual context, improve pacing, and make videos more engaging.

B-roll can include close-up shots, environmental footage, demonstrations, reactions, or cutaway scenes.

B-Roll vs. A-Roll

A-roll contains the primary dialogue or main action that sets the story in motion, while B-roll supports the story visually and adds context to the main narrative.

For example:
A-roll: A presenter talking about what's taking place in their city
B-roll: Footage to show the city and its major landmarks

Using both together creates more polished and professional videos.

Why B-Roll Matters

B-roll helps videos feel more dynamic and visually engaging while supporting storytelling and clarity.

B-roll makes videos better by:
Breaking up long talking-head shots
Adding visual context and detail
Improving pacing and engagement
Helping cover edits or transitions
Making instructional content easier to follow

Whether you're creating lessons, tutorials, marketing videos, or social content, B-roll helps maintain viewer attention.

Example Use Cases for B-Roll

  • Business and Training: An onboarding video includes workplace footage while a narrator explains company procedures.

  • Marketing and Content Creation: A creator reviews a product while B-roll highlights product features and close-up shots.
