The best AI tool for generative b-roll & video
for video editors
We tested the best AI tools for generative b-roll & video for video editors in 2026. Here's what won, and what the runners-up are good for.
Runway
After testing against real video editors workflows in Q1 2026, Runway is the clear winner for generative b-roll & video. It excels where other tools fall short: text- and image-to-video generation. The gap between Runway and the runners-up is meaningful in day-to-day use.
What separates Runway from the competition is how it handles the edge cases that come up in real video editors work, not just the showcase demos. For video editors specifically, that distinction matters more than raw benchmark scores.
What it gets right
- Strongest control tools (motion brush, camera moves)
- Image-to-video keeps shot consistency
- Inpainting and green-screen tools built in
Where it falls short
- Clip length and resolution still limited
- Costs credits that add up at volume
- Not a substitute for filmed primary footage

Common questions about AI for generative b-roll & video
Can generative video replace shooting B-roll?
For abstract or impractical-to-film shots, yes. For anything that needs to match real, specific footage, it's a supplement.
How long can generated clips be?
Still short, typically a handful of seconds per generation, which you extend or stitch. Plan around that.
Is the output broadcast quality?
Improving fast, but resolution and artifacts still show on close inspection. Best for social and concept work today.
Which tool has the most control?
Runway: motion brush, camera controls, and inpainting give it the finest steering of the generative tools we tested.
