AI B-roll for every gap in your edit

What B-roll does

B-roll is the supporting footage that plays over narration or between scenes: the city skyline before an interview, steam rising from a cup in a coffee review, a slow pan across a map in a history video. It controls pacing and keeps viewers watching. The problem is that the shot you need is often one you did not film.

Why AI B-roll is useful

• Exact match. Describe the precise moment your script mentions instead of searching stock libraries.
• Professional camera language. Choose shot size, angle, lens and movement: an 85mm close-up, a low-angle push in, an aerial drone shot.
• Consistent look. Keep the same style and light across a whole video.
• Any format. 16:9 for YouTube and films, 9:16 for vertical edits, 1:1 for feeds.

Shots worth generating

Establishing shots: skylines, landscapes, buildings at golden hour. Cutaways: hands typing, coffee pouring, pages turning. Textures: smoke, ink in water, light leaks, rain on glass. Transitions: whip pans, fast drone moves, zooms. Concept shots: abstract visuals for ideas that cannot be filmed.

How to get usable B-roll

1. Write what the shot shows, where, and the light, in one sentence.
2. Open Camera and choose one move plus a shot size and lens.
3. Pick Cinematic or Vintage film for a filmic look, or no style for neutral footage.
4. Generate 16:9, then drop the clip into your timeline.

Matching B-roll to your narration

The fastest way to plan B-roll is to read your script line by line and note the noun or action each line is about. A line about a market crash needs falling numbers on a screen or an empty trading floor; a line about a quiet village needs a slow wide shot at dawn. Write one prompt per line, keep the same style and light words in every prompt, and the clips will cut together as if they were filmed on one shoot.

Keep each clip on screen for two to four seconds. Because every clip is 5 to 10 seconds long, you always have handles to trim from the start or end, which makes it easy to land the cut on a beat or a word.

Common mistakes to avoid

• Too many subjects. One clear subject per shot reads better than a busy scene.
• Mixed camera moves. Choose one movement per clip. A push in plus an orbit plus a tilt looks restless.
• Changing the light. If your edit is at night, keep every prompt at night.
• Forgetting the shape. Generate 16:9 for a wide edit; cropping a vertical clip later loses detail.
