Frequently asked questions
What’s an AI B-roll generator?
An AI B-roll generator is a tool that creates B-roll footage to complement a main storyline, like talking head videos or other kinds of voiceover or plot. These videos provide context, build visual interest, or establish a scene.
Can I customize the generated B-roll videos?
Yes, B-roll editing is a snap with Captions. Simply generate a new clip by typing in a prompt or use the chat-based editor to suggest changes.
Why should I generate B-roll with AI instead of using stock footage?
There are a few reasons. First, stock libraries usually require a separate subscription. With a tool like Captions, you get an all-in-one video editor and custom B-roll. Second, stock footage might not fit your needs. AI clips are endlessly customizable, so they’ll always fit your message. Third, you’ll save time. Even if stock libraries have the clip you want, it may take you hours to find it. That’s not the case with AI — all you need to do is describe the clip, and the tool will handle the rest.
