How it works
Describe the exact shot
Subject, motion, setting, camera, light — or let the prompt assistant interview you and write the shot description in director's language.
Pick the model per shot
Budget models (~$0.036/s) for atmosphere and cutaways; Kling for people in motion; a flagship for the shots viewers will actually study. The cost shows on the button before you generate.
Generate a few takes
B-roll thrives on options. Three takes of a 5-second draft cost well under a dollar — pick the one that cuts best.
Trim and export — or keep it in the project
Use generated b-roll inside a SpeedReel edit directly, or export clean clips to drop into any external NLE.
Why SpeedReel for this
Specificity stock can't match
Stock search gives you what exists; generation gives you what the script says. Niche subjects, exact palettes, matching screen direction — all promptable.
Owned, not licensed
No per-clip licenses, no seat-based subscriptions, no 'also seen in three competitors' ads' problem.
Costs measured in cents
A 5-second draft clip costs roughly $0.18 on the budget tier. An afternoon of b-roll costs less than one premium stock clip.
Common questions
Is AI b-roll good enough for client work?
For cutaways, atmosphere and transitions — routinely yes, especially at feed resolutions. For hero shots, generate on a flagship model and review takes; regeneration is cheap.
Can I use generated b-roll commercially?
Generation runs on commercially licensed model access; as always, check the specific model's terms for your use case before shipping client work.
What resolution does export support?
720p or 1080p, rendered in-browser with no upload queue or render-farm wait, in the aspect ratio your project uses.
