What is AI B-roll?
AI B-roll is supporting footage generated from a prompt or image rather than captured on a camera. Use it to establish a place, show a detail, cover an edit or add atmosphere between a main talking-head or product shot.
- Use it as a cutaway, transition or atmosphere shot.
- Keep one visual idea per clip so it can be cut cleanly.
- Generate matching ratios for each destination.
- Record or review the rights, disclosure and factual accuracy of each generated scene.
How do you create B-roll with Everygen?
Start with either a written scene or a first-frame image. Describe one location, one action and one camera move, then generate a short draft. A useful sequence is city establishing shot, object detail, subject cutaway and matching transition.
Use text-to-video when the scene is conceptual and there is no production still.
Use image-to-video when a product, location or frame must remain visually consistent.
Generate a short version first and expand only after the motion works.
Keep the edit simple: one shot should solve one timing problem.
How do you write a strong AI B-roll prompt?
Name the place, the visual event and the camera movement. For example: “rainy city street at dusk, warm window reflections, slow dolly zoom, no people, cinematic parallax, stable architecture.”
- Use a specific verb: push, glide, rise, orbit, dolly zoom or hold.
- Describe a time of day, weather condition or light source.
- State what should not change: buildings, product shape or horizon line.
- Avoid multiple actions, cuts or story beats in one clip.
Which model should you use for AI B-roll?
Kling 3.0 Turbo is the lower-cost draft model for 720p clips up to 15 seconds. Seedance 2.5 adds 1080p, audio and longer clips, which helps when the B-roll needs an ambient sound bed or a slower edit.
A 4-second Kling 720p clip costs 9 credits; an 8-second clip costs 18 credits.
A 4-second Seedance 720p clip costs 16 credits; 1080p costs 18 credits.
Use the model comparison page when clip length, audio or resolution is the deciding factor.
What can Everygen not do for B-roll?
Everygen does not provide timeline editing, automatic shot matching, batch production or guaranteed physical continuity across separate generations. It creates individual shots that you assemble and review elsewhere.
Keep recurring characters, products and locations as first-frame references when consistency matters.
Check generated geometry, people, signs and product details before publishing.
Use licensed music, voiceover and captions in the edit rather than assuming native video audio is a final soundtrack.
What are good prompt examples?
Strong prompts describe a visible action, one location and one camera direction. Adapt the subject and product details rather than copying a prompt without checking the result.
Rainy city transition
Slow dolly zoom down a rain-slick city street at dusk, warm shop-window reflections, dramatic blue clouds, no people, stable building geometry, cinematic parallax and subtle edge motion blur.
Product insert
Macro camera glide across an unbranded ceramic cup on a stone table, light steam rises, soft morning window light, keep the cup shape and surface texture stable, calm product B-roll.
Nature establishing shot
Low aerial-style glide over coastal grass toward calm blue water, gentle wind moves the grass, early morning light, keep horizon stable, cinematic travel B-roll, no people or text.
B-roll shot planning guide
Credit totals use the current Everygen studio settings and are rounded up to a whole credit for each generation.
| Edit need | Shot idea | Suggested length | Best model |
|---|---|---|---|
| Location reset | Slow city glide | 4–8 sec | Kling draft |
| Product detail | Macro push-in | 4 sec | Kling or Seedance |
| Atmosphere | Weather and light | 6–10 sec | Seedance |
| Transition | Parallax reveal | 4–6 sec | Kling draft |
What matters most before you generate?
- Start with one clear action and one camera direction so the model has a specific motion to solve.
- Upload a clean first frame whenever product shape or a particular scene must stay consistent.
- Test a short, lower-cost generation before committing to a longer Seedance render.
- Review text, hands, product details, audio and disclosure requirements before publishing.
