Prompt to video
AI B-roll gives you another way to fill a gap discovered in the edit. Describe the cutaway you need, review the generated take and trim it alongside the footage already on your timeline.
Describe the missing shot for AI B-roll
You already know what the shot is: hands on a keyboard, rain on a window, the street at dusk. Writing that sentence is faster than scrolling a library for something adjacent to it.
Real prompt, real output. Only the wait is sped up — a render takes a few minutes.
Why it holds up
Match the footage it sits next to
A cutaway that disagrees with the scene reads as an insert from another film. Pull a still out of your own footage and animate that, so the light and the look carry over instead of being described from memory.
It lands where the hole is
The generator lives in the app the project lives in. The clip arrives on the timeline under the voice track and gets trimmed to the gap there, not exported out of one tool and back into another.

Questions
How long can an AI B-roll clip run?
A few seconds per generation, which is about as long as a cutaway should hold anyway. For a longer stretch, generate two angles of the same scene and cut between them — that reads better than one shot held past its welcome.
Is generated b-roll better than stock?
Stock is real footage and it is instant, and for a generic city skyline it wins. Generation wins when the shot is specific — your product, your setting, an idea nothing was ever filmed for. Bunsy has no stock library; what it has is the ability to make the shot.
Do I need to disclose a generated cutaway?
A synthetic shot inside otherwise real footage is exactly what the platform rules are written about. Label it where the platform asks — the alternative is a strike on a video that was fine.
