Turn a simple text prompt into cinematic B-roll in minutes. The AI B-roll generator builds ready-to-cut footage with no cameras, no stock fees, and no editing software, for ads, explainer videos, and social content.
Key featuresAI B-roll generator features
Generate B-roll footage from prompts
Describe a scene and the AI will generate ready-to-edit B-roll footage in minutes, with no stock library or film crew required. The latest text-to-video models in HeyGen, including Veo and Kling, transform your prompt into high-quality cinematic cutaways, product shots and animated backgrounds.
Turn photos into high-quality B-roll
Drop in a still or snap a photo, and the image-to-video engine adds pans, zooms, and camera motion to create smooth B-roll. Set your video’s shot direction from a short prompt, so a single brand asset becomes a polished scene without filming.
Auto-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 first edit.
Match on-brand B-roll and colour
Swap generic stock for your own brand assets to match your look and enhance every scene. Adjust pacing, refine transitions and apply professional-grade colour grading so dynamic visuals stay on message. Pair generated footage with an AI spokesperson to anchor the story.
All-in-one platform, from script to video
Go beyond clips to create a finished video on one 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 for a video that's ready to publish.
Use cases
Agency shoots drain budgets and weeks. Marketers generate scroll-stopping cutaways and motion scenes from a script to save time and engage buyers, then drop them into marketing videos ready for every channel.
Filming fresh clips every day is slow and inconsistent. Turn quick ideas into cinematic B-roll and hooks that boost reach, then publish viral TikToks, Reels and Shorts with a TikTok video workflow designed to drive engagement.
Filming a polished demo takes planning, equipment and editing. Describe the feature and generate relevant B-roll and close-ups that complement your product demo with seamless cuts, so it looks professionally produced and ready to publish.
Abstract ideas are hard to convey with talking heads alone. Add animated concepts and supporting footage so an AI video explainer makes complex topics easy to grasp, turning dense scripts into clear, engaging stories.
Reshooting training footage for every update is costly. Generate real-world scenes that clearly show each step in a training video, then edit the script and regenerate the footage to keep content production moving whenever the material changes.
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.
How it worksHow the AI B-roll generator works
Create cinematic B-roll in four steps, taking you from a written prompt to polished footage that's ready to edit.
Choose a format, aspect ratio and visual style, then set the mood and direction for the scene.
Describe the scene you want or add a reference image, and the system will plan the shot.
The AI renders cinematic B-roll with smooth motion in minutes, with no stock library or filming required.
Adjust pacing, transitions and colour, then export in any aspect ratio for ads, social media or YouTube.
An AI B-roll generator turns a text prompt or reference image into footage that's ready to edit. This AI tool reads your script, identifies the scenes you need and generates cinematic cutaways, product shots and motion backgrounds for a faceless video or any other project.
