Every talking-head video needs cutaways — B-roll that illustrates what you're saying and keeps viewers from staring at your face for ten straight minutes. Filming or licensing enough of it is expensive and time-consuming. AI now fills that gap two ways: generating original footage from a prompt, or automatically matching your script to relevant stock clips. Here are the three best tools for it in 2026.

★ Editor's quick pick

Runway

The only option here that generates genuinely original footage — useful when stock libraries can't provide the specific shot your script needs.

When your script needs a very specific visual — something no stock library carries — Runway generates it from a text prompt. It's the tool to reach for when you want your B-roll to look distinctive rather than like every other creator's stock footage.

Frequently asked questions

What is the best AI tool for generating B-roll?
Runway produces the most original, distinctive generated footage. Pictory is better when you want stock footage automatically matched to your script rather than generated from scratch, and CapCut is the convenient option if you're already editing there.
Is AI-generated B-roll good enough to use professionally?
For background cutaways, illustrative shots and abstract concepts, quality is generally strong enough. For anything requiring precise realism or specific real-world locations, licensed stock or your own footage still tends to look more convincing.
Do I need stock footage licences for AI-generated B-roll?
Generated footage from tools like Runway is typically covered under your subscription's commercial terms, not a separate stock licence — but always check the specific plan's commercial usage rights before using it in monetised content.

The bottom line

Runway is the best source of original B-roll your script needs but stock libraries don't have, Pictory is the fastest way to auto-match existing stock footage to a script, and CapCut is the convenient option if you want quick generated clips inside your regular editor.
