FAQs
What is B roll?
B-roll refers to supplementary video footage used to support the main footage (also called A-roll) in a video. For example, while someone is talking about a product, B-roll might show the product in use, close-up details, screen recordings or related scenes. B-roll helps make videos more engaging, visually appealing and easier to understand by adding context and variety.
What is an AI B roll generator?
An AI B roll generator is a digital tool that uses AI technology to create contextual B roll footage based on your script, transcript, images or video content. It can automatically suggest relevant scenes by creating an AI script, generate dynamic visuals and match the footage to the theme, style and pacing of your video. Such tools help creators produce more engaging videos faster without having to search for every clip manually or arrange extra shots.

Yes. Fotor’s AI B-roll generator can read and analyze your video content, understand the key moments, write an AI script to suggest relevant B-roll footage and generate relevant scenes that align with the topic, style and pacing.

What is the difference between AI-generated B-roll and AI-matched stock footage?
To put it simply, AI-generated B-roll refers to new footage created by an AI tool based on its understanding of the video content. AI-matched stock footage is the one that an AI finds from existing footage that fits your content online.

Can I use AI B-roll for YouTube, TikTok, Instagram Reels and Shorts?
Usually, yes. But you should be aware that the subject in your video should not be a copyrighted character, logo, product or anything similar. If you create a B-roll clip based on these materials and share it on social media for commercial use without the creator’s consent, it will be absolutely illegal.
Can AI B-roll make my talking-head or podcast videos more engaging without covering the speaker?
Yes. You upload your talking head or podcast videos to Fotor’s AI B-roll maker and let it create professional, engaging B-roll scenes.

You can easily apply a picture-to-picture effect to seamlessly insert your B-roll clip into the video and adjust its size to ensure it does not cover the speaker.
Can I edit or replace an AI-generated B-roll clip after it is added?
Yes. You can replace an AI-generated B-roll clip through your chats with our tool. Since the AI-generated B-roll footage will appear in our video editor, you can conveniently edit it even after it is generated. For instance, you can trim and crop it, adjust its playback speed, increase its volume, add stylish captions and background music and more.
How do I avoid generic or repetitive AI B-roll?
With Fotor, yes. You can rely on it to create contextual B roll footage based on its understanding of your original video content. So, you don’t need to search for existing stock footage, which can be generic or repetitively used by other users or brands.
