The production of videos that look professional requires more than just a camera or good audio, it requires telling an engaging story visually. And this is where using B-roll will come in handy too. Using the appropriate B-roll can quickly add excitement and engagement to your content, whether you're producing corporate explainers, Instagram Reels, TikToks, or YouTube videos.

What is B-Roll?

B-roll refers specifically to additional footage used in video production that generally augments your A-roll content. If your A-roll is you talking directly to the camera, your B-roll would be clips filmed of the product you're discussing or relevant environment/animation visuals.

For example, if you're explaining how to drink coffee, the A-roll could be you describing the process, while the B-roll could be footage of coffee beans being ground, water being poured into a kettle, steam rising from a cup, etc. It enhances visual engagement for viewers, gives a professional feel to your video, and highlights certain points without overwhelming viewers with your constant face.

B-roll video has traditionally been either shot manually or bought from stock video distributions. However, AI B-roll generators have now made it possible for you to generate video that automatically matches your audio.

This guide takes a look at the best AI B-roll generators, comparing their features, applications, and why they could be rounded into your workflow.

Why AI B-Roll Generators Matter

Traditionally, creators only had two options: shoot their own b-roll (expensive and time consuming) or purchase stock footage (it can get costly and generic). AI b-roll generators help alleviate both concerns by:

• Analyzing all of your video content to understand the theme, tone and keywords. 

• Auto-matching potential visuals, animations or stock clips that are relevant. 

• Minimize wasted time searching and editing. 

• Consistency with their brand style with filters, transitions and caption integration. 

Overall, they simplify the ability to create engaging, cinematic videos to anyone who has a camera (beginner or pro) without requiring a major budget or team.

1. Pictory – B-Roll for Script-Driven Videos

Pictory is a well-known AI tool for converting scripts into polished-looking videos, and one of its best features is the automatic matching of B-roll. When you paste your script in, Pictory will find stock clips or create AI generated images that correspond with each individual line.

This is good for educational or explanatory type content or narrated content where the visuals are built completely around the audio. The ability to automatically match B-roll and narration saves hours of editing time. However, it is more a style for corporate and informational video formats vs. cinematic or creative storytelling

2. Runway ML – Creative and Consistent

Runway ML isn't just an AI B-roll generator; it's a complete creativity ecosystem. You can generate cinematic B-roll from scratch using text prompts, you can remove or replace backgrounds, and you can replicate the style of your A-roll footage so you can transition more seamlessly. 

For example, if your main shot is a warm vintage kitchen scene, you can tell Runway to generate B-roll in the same tone and lighting. It caters to creators who want visual cohesion across their video. The learning curve is a little more steep than other more simple tools, but it's worth the creative control.

3. Synthesia – B-Roll for AI Presenter Videos

Synthesia is predominantly known for its AI avatars, but it also introduces B-roll into the generated videos. If you create a talking head type video with a virtual presenter, Synthesia will integrate the B-roll by automatically cutting away to appropriate images. An example here would be a graph that appears when data is mentioned, or an image of an office space that appears when a corporate message is included.

If you are producing a video for your business, or developing an online course, this is beneficial because you can keep the audience engaged without messing with the adds later. The downside is that it is less flexible for pure creative or cinematic projects.

4. Veed.io – Fast and User-Friendly

Veed.io provides a user-friendly interface that allows users to add AI-recommended B-roll. You upload your main footage, and Veed will analyze the content of your footage and suggest appropriate cutaways from its stock library or create them using AI.

Veed makes for a terrific option if you are looking for speed and simplicity without the need for a lot of customized work. You are able to add captions to your video on Veed; however, if you want something more refined in terms of styling or translations, you can pair it with Typei to achieve a more polished final product.

How to Choose the Best AI B-Roll Generator

Choosing the right AI B-roll generator is dependent on the style of your content, your budget, and your level of technical skills. Here's a quick summary of the options available: we want to think about how you work. Do you produce mostly scripted videos? Is visual style consistency important to you?
