AI B-Roll Generator: Make Cinematic Stock-Style Footage from Text

An AI b-roll generator makes supporting footage, the cutaway shots that play under a voiceover or between talking-head clips, from a written description instead of a shoot or a stock library. AdAnt's generator makes a 5-second, 720p cinematic clip with natural ambient sound and the camera move you choose: a push-in, a drone pull-back, a handheld follow or a locked-off tripod shot. In AdAnt Studio the clips drop straight into the video editor beside your avatars, voiceovers and captions.

YouTube videos and explainers

Cover a voiceover with footage that matches each sentence, instead of searching stock sites for something close enough.

Ad cutaways

Cut a lifestyle shot between UGC talking clips so a product ad breathes and shows the setting it is used in.

Local business promos

Show a café, salon or gym with cinematic footage for a Reel or a website header without booking a videographer.

Agency pitch reels

Build a moodboard in motion for a client so the look of a campaign is agreed before the shoot.

AI B-Roll Generator FAQ

Tips for a better result

Describe one shot, not a sequence; each clip holds one continuous camera move.
Name the time of day and the light source: window light, neon, golden hour or overcast.
Use the tripod shot when you will put text or captions over the footage, so the frame stays calm.
Generate the same scene with two camera moves to have a cut ready in the edit.

Is the AI b-roll generator free?

Yes, you can try it free. A free AdAnt account comes with credits, and one 5-second b-roll clip with sound uses about 6 credits.

Can I use AI b-roll in ads and monetized videos?

Yes. Use the clips in your own ads, YouTube videos and posts, and follow each platform's rules on labeling AI-generated content. Videos made on a free account are watermarked previews; paid plans download them without the watermark.

Is AI b-roll better than stock footage?

It is made to your exact description and framing, so it fits the line it plays under. Stock footage is real camera footage; use whichever matches the shot you need.

Does the b-roll have sound?

Yes. Each clip comes with natural ambient sound of the place, such as café noise or wind, which you can keep low under a voiceover.

Can I make vertical b-roll for Reels and TikTok?

Yes. Pick Vertical 9:16 for TikTok, Reels and Shorts, or Square 1:1 for feed posts.
