About B-Roll Factory
B-Roll Factory is an AI video agent that turns a one-line scene description into ready-to-cut b-roll — the filler footage editors actually reach for. It is built for creators and video editors who are tired of scrolling stock libraries and clearing licenses: type "rain on a cafe window at night" and get an establisher you can drop straight onto the timeline. A server-side style DNA keeps clips looking like footage, not slideshow motion, and session memory lets you tweak the last render instead of rolling a fresh one.
What you can create with B-Roll Factory
- Environmental establishers — city streets, interiors, landscapes, weather
- Insert and detail shots — hands typing, coffee pouring, machinery, textures
- Transition footage — whip pans, push-ins, rack focus moves between scenes
- Mood and atmosphere clips — light through blinds, steam, crowds, traffic at dusk
- Matching-look b-roll to fill gaps in an existing edit
Sample prompts to try
- ☕ Steam curling off a fresh espresso in warm morning window light, slow push-in
- 🌆 A rain-slicked city skyline at dusk, drifting aerial parallax over glowing windows
How to use B-Roll Factory
- 1Describe the scene in plain language — location, subject, time of day, mood.
- 2Add the shot type if it matters (e.g. "slow push-in", "static wide", "overhead insert").
- 3Generate, then refine on the previous clip instead of re-rolling — the agent holds the look steady across takes.
- 4Download in your edit’s aspect ratio and cut it in.
Frequently asked questions
How is this different from a stock footage library?
You describe the exact shot you need and get it in seconds, instead of scrolling clips that almost fit. There is no licensing to clear — the footage is generated for your prompt. And because a style DNA is assembled into every request server-side, a batch of clips shares one consistent look rather than the mismatched grades you get stitching stock from different shoots.
Will the clips match the rest of my edit?
That is the point of the session memory. Generate one clip, then say "same street, now at night" or "hold this look, tighter framing" and the agent iterates on the previous render — so a run of b-roll stays on-look instead of drifting shot to shot.
Is B-Roll Factory free to try?
You can generate before signing in — the login prompt appears when you hit send. Video runs on a credit system priced above stills, so you can test the look before committing credits to a full batch.
Can I control the camera movement?
Yes. Name the move — "slow push-in", "left-to-right pan", "static locked-off wide" — and the agent treats it as the shot’s dominant idea, so the b-roll cuts cleanly next to your A-roll.
