B-roll
B-roll is supplementary footage cut over or between the main shot (the A-roll) — product close-ups, screen recordings, location shots, stock clips, or cutaways that illustrate what the speaker is saying. The audio usually stays on the A-roll while the picture changes. In short-form video, B-roll does two jobs: it shows the thing being described so the viewer does not have to imagine it, and it resets attention on a talking-head clip that would otherwise hold one static frame for 40 seconds. Good B-roll is specific to the sentence it covers. Generic stock of people typing on laptops fills time but explains nothing, and viewers learn to scroll past it.
In a HypeNest pass
HypeNest can add AI B-roll to clip candidates cut from a long video. Review each insert the same way you review the cut: does it show what the line says, does it hide the speaker at the moment their face carries the point, and does it cover on-screen text you needed? Remove inserts that are decorative.
FAQ
- What is the difference between A-roll and B-roll?
- A-roll carries the story — usually the person speaking. B-roll is the supporting picture laid over that audio. Remove the B-roll and the clip still makes sense; remove the A-roll and it does not.
- Can I use stock footage as B-roll on YouTube Shorts and TikTok?
- Yes, if the licence covers social use. Check the stock provider’s terms and avoid clips with watermarks or recognisable brands you are not cleared to show.
