Quick Summary

Finding the Right B-Roll Shot for Your Video

You are editing a product tutorial and need footage of hands typing on a keyboard. Or you are cutting a marketing video that requires establishing shots of a coffee shop. Searching stock libraries takes time, licensing adds cost, and clips often do not match your video.

AI B-roll generators create custom clips from text prompts in seconds. These tools reduce reliance on stock libraries, simplify licensing, and speed up video editing workflows.

In this Klap article, we review seven AI B-roll generators, comparing output quality, pricing, ease of use, and ideal use cases to help creators, small teams, and media companies find the right tool for their workflow.

What is an AI B-roll Generator?

Before selecting an AI B-roll generator, it helps to understand the role of B-roll.

B-roll is supplemental footage in video production that supports the main narrative. It provides context, visual detail, and depth, often showing scenery, reactions, or additional actions that complement the primary storyline.

An AI B-roll generator automates this process. It uses artificial intelligence to analyze your content and create relevant, high-quality B-roll clips, reducing editing time and streamlining video production.

For example, if a YouTuber explains how they edit videos, the talking-head clip is the A-roll. Screen recordings of the software, timeline zoom-ins, or previews of the final video are B-roll.

In short, A-roll tells the story, and B-roll shows it.

Why B-roll is Important in Video Content

B-roll supports the main narrative, adds visual variety, and enhances the viewer experience. Here are the main ways B-roll adds value: 

• Enhances Visual Appeal: B-roll adds variety to static shots by showing different angles, actions, or scenes. This keeps viewers visually engaged while supporting the main story.
• Improves Storytelling: B-roll adds context by showing the environment, speaker reactions, or relevant actions. This helps viewers better understand the A-roll content and follow the narrative more clearly.
• Creates Seamless Transitions: B-roll fills gaps between scenes or topic changes, allowing the video to flow smoothly. It reduces abrupt jumps and keeps the narrative visually consistent.
• Supports Viewer Engagement: Strategic B-roll, such as close-ups, cutaways, or illustrative actions, keeps the video visually varied. This helps maintain viewer attention throughout the content.
• Elevates Production Quality: High-quality B-roll improves the overall look of a video. It allows creators to produce polished, professional content even with minimal original footage.
