Main featuresAI B-Roll Generator features
Create B-roll footage from prompts
Describe a scene, and the AI will generate ready-to-edit B-roll footage in minutes, without a stock library or film crew. The latest text-to-video models available in HeyGen, including Veo and Kling, transform your prompt into high-quality cinematic cutaways, product shots and animated backgrounds.
Transform photos into high-quality B-roll
Upload a still image or take a photo, and the image-to-video engine adds pans, zooms and camera movement to create smooth B-roll. Set the direction of your shot with a short prompt, turning a single brand asset into a polished scene without the need to film.
Automatically edit takes in the AI video editor
Speech Cleanup automatically edits your A-roll takes, removing filler words, pauses, false starts and retakes. It then takes care of the video editing by stitching together the best clips. Invisible transitions bridge every gap in the AI video editor, so your footage looks polished from the outset.
Match on-brand B-roll and colour
Swap generic stock for your own brand assets to match your look and elevate every scene. Adjust pacing, refine transitions, and apply professional-grade color grading so dynamic visuals stay on message. Pair generated footage with an AI spokesperson to anchor the story.
All-in-one script-to-video platform
Go beyond clips and create a finished video on a single, all-in-one platform. Paste a brief into the script-to-video workflow, and Video Agent will write the script, build the storyboard, generate matching B-roll, and add dynamic voice-over and subtitle tracks to produce a video that is ready to publish.
ApplicationsWays to use the AI B-Roll Generator
Connect with buyers through AI video adverts
Agency shoots consume budgets and take weeks. Marketers can create attention-grabbing cutaways and motion scenes from a script to save time and engage buyers, then add them to marketing videos ready for every channel.
Social clips that broaden your reach
Filming new clips every day is time-consuming and inconsistent. Turn quick ideas into cinematic B-roll and hooks that extend your reach, then publish viral TikToks, Reels and Shorts using a TikTok video workflow designed to boost engagement.
Product demos with seamless B-roll
Producing a polished demo takes planning, equipment and editing. Describe the feature and generate relevant B-roll and close-ups that complement your product demonstration video, with seamless cuts for a studio-quality result that is ready to publish.
Explanatory videos and visual storytelling
Abstract ideas can be difficult to convey with talking heads alone. Add animated concepts and supporting footage to help an AI video explainer make complex topics easier to grasp, turning dense scripts into clear, engaging stories.
Expand training content production
Reshooting training footage for every update is costly. Generate lifestyle scenes that identify and illustrate each step in a training video, then edit the script and regenerate the footage to keep content production moving whenever the material changes.
Long-form and creator channels
Stop sourcing fresh stock for every episode, podcast, or repurposing project. Generate unlimited B-roll on demand to power YouTube video generator workflow, keeping a consistent look for creators across hundreds of episodes.

Frequently asked questions (FAQs)
What is an AI B-roll generator and how does it work?
An AI B-roll generator turns a text prompt or reference image into footage that is ready to edit. This AI tool analyses your script, identifies the scenes you need, and generates cinematic cutaways, product shots and animated backgrounds for a faceless video or any other project.
Can AI B-roll deliver professional-quality results on screen?
Yes. Footage comes from leading models available in HeyGen, such as Sora, Veo, Kling and Seedance, with fluid motion, realistic lighting and depth. Refine pacing, transitions and colour grading within the AI video generator so that every scene delivers professional results.
Do I have to trawl through stock sites or Pexels for B-roll footage?
No. Rather than trawl through stock sites such as Pexels, the generator intelligently identifies the scenes your script requires and creates original B-roll footage on demand. You can also keep generated clips in a media library for reuse across projects.
Can I generate B-roll from my own videos and images?
Yes. Add your own videos and images, and the system applies natural motion, panning and camera movements. It is a quick way to turn existing assets into footage for a product video, without reshooting or needing a stock media subscription.
Can I upload my own video and add B-roll footage using the AI-powered editor?
Yes. Upload your video and the AI-powered editor lets you add B-roll footage where it reinforces your message. Relevant cutaways can improve your videos and give your content a polished finish, without hours of manual editing.
Can I add subtitles and captions to B-roll with one click?
Yes. The subtitle generator adds subtitles and captions with one click, then synchronises them with your voice-over. Download a shareable video file in any aspect ratio, with the subtitle track embedded or kept separate.
Can I use AI B-roll commercially in adverts and client work?
Yes. Footage generated on a paid plan includes full commercial rights for adverts, product launches and client work. Add clips to an AI advert maker workflow or any other deliverable. Free exports include a watermark; paid plans remove it and permit full commercial use.
How much B-roll can I generate, and is there a limit on the number of clips?
You can create environment clips, product close-ups and motion backgrounds in batches in the App Library before your main edit. Paid plans unlock unlimited generations, so you can build a complete library of cutaways for a campaign or channel without per-clip fees.
Why use a B-roll generator rather than a stock footage library?
Stock libraries offer generic clips that other brands also use, and licensing fees soon add up. A B-roll generator creates footage tailored to your specific scene and brand, making the visuals feel original. Pair it with a video script generator to plan and produce everything in one place.
Will the B-roll generator work with my editing workflow and integrations?
Yes. The scene-based interface fits into your existing video-editing workflow, with API integration for batch jobs. Generated B-roll matches the feel of your project, so cutaways slot straight into your timeline without disrupting your creative flow.
Is the AI B-roll generator free to use, and what do the paid plans include?
You can get started at no cost, with no credit card required, and generate footage to try the workflow; exports on the Free plan include a watermark. Paid plans start at $24 per month and remove the watermark, whilst unlocking higher resolutions, longer videos and full commercial rights.
Can I add a voice-over to B-roll and download the finished video?
Yes. Combine generated clips with a presenter, AI voice-over narration, music and captions in the same project. Everything is rendered together on a single timeline, and you can download the finished video in HD or share it directly to your channels.
Can I use AI-generated B-roll in a video podcast?
Yes. Generate cutaways, animated backgrounds and establishing shots that support each discussion topic, then add them to episodes created with the AI podcast generator.
Can I add AI B-roll to a presentation video?
Yes. Generate supporting footage from prompts, then add it to scenes created through the PPT-to-video workflow to make slide-based content more visually engaging.
Can I add AI B-roll when turning a PDF into a video?
Yes. Generate relevant cutaways and motion scenes based on the document's topics, then incorporate them into content created using the PDF-to-video workflow.
