Top 7 AI B-Roll Generators for Faster Video Editing

TL;DR

If you’re editing videos regularly, AI B-roll generators can save you hours on every project by automatically adding relevant visuals to your timeline.

• Tools like Submagic and Gling.ai prioritize speed and automation.
  
• Tools like OpusClip focus on understanding long-form content and context.
  
• Kapwing and VEED.io balance AI assistance with manual editing.
  
• Magic Hour stands out by generating original B-roll instead of relying on stock footage.
  

There is no universal “best” AI B-roll generator. The right choice depends on how you edit, how often you publish, and how much creative control you want.

AI B-roll generators aim to eliminate the most time-consuming part of video editing: searching, downloading, and syncing stock footage.

In practice, these tools analyze your script or transcript, identify moments that need visual support, and automatically insert relevant clips. The promise is simple-turn hours of manual work into minutes.

But not all AI B-roll tools solve the same problem. Some optimize for speed. Others focus on context, creative control, or visual originality. After running the same workflows through each tool, one thing became clear: the “best” option depends entirely on how you edit and publish videos.

This guide breaks down the top AI B-roll generators, side by side, so you can choose confidently.

What Is B-Roll - and Why AI Changes Everything

B-roll refers to supplemental footage that supports your main video (A-roll). This can include stock clips, screen recordings, cutaway shots, background visuals, or atmospheric scenes that appear while someone is speaking.

Traditionally, adding B-roll is the slowest part of editing. You search stock libraries, guess keywords, preview dozens of clips, download them, and then manually sync everything to your narration. For long-form videos, this alone can take more time than filming.

AI B-roll generators change the workflow entirely.

Instead of searching manually, these tools analyze your transcript, detect key concepts, and automatically insert relevant visuals at the right moments. Some tools pull from stock libraries. Others generate entirely new video scenes. The goal is the same: reduce editing time without sacrificing clarity or engagement.

From my testing, using AI B-roll typically cuts hours of manual work down to minutes, especially for talking-head videos, podcasts, and educational content. The biggest shift isn’t just speed - it’s momentum. You spend less time stuck in the timeline and more time publishing.

That said, not all AI B-roll tools solve the same problem. Some are optimized for viral short-form content. Others are better for long-form repurposing, brand videos, or YouTube workflows. Understanding these differences is key to choosing the right tool.

Best AI B-Roll Generators at a Glance

Magic Hour

Best for: Creators and teams who want B-roll that doesn’t look like stock footage.

Magic Hour approaches B-roll differently. Instead of pulling from a traditional stock library, it generates original video scenes using AI. This makes it especially useful when stock clips feel repetitive or visually off-brand.

After testing it across explainer and narrative videos, Magic Hour stood out for visual originality. The generated footage feels designed, not searched.

Pros

• Generates original B-roll instead of reusing stock
  
• Strong control over visual style and mood
  
• Avoids “seen-it-everywhere” stock clips
  

Cons

• Requires more prompt thinking than one-click tools
  
• Less ideal for ultra-fast social edits
  
• Not built around captions or emojis
  

My take:
Magic Hour earns its place in this list because it solves a problem most AI B-roll tools don’t even try to address: visual sameness. Instead of pulling from the same stock libraries everyone else uses, Magic Hour generates original video scenes from prompts. In practice, this means your B-roll doesn’t look like “filler” - it feels intentionally designed for the video.

In my testing, Magic Hour worked best when I already had a clear narrative or visual direction. For explainer videos, brand stories, or abstract concepts that are hard to find in stock libraries, it consistently produced usable footage faster than manual searching. You trade a bit of speed for originality, but the payoff is content that doesn’t immediately register as AI-assisted stock.

This tool is especially effective when paired with voiceover-led content. You can generate visual scenes that match tone and pacing rather than literal keywords. That makes it useful for startups, agencies, and creators who care about brand identity and visual cohesion.

That said, Magic Hour isn’t designed for “publish in five minutes” workflows. If your goal is rapid social clipping with captions and emojis, it’s not the fastest option. But if you’re tired of generic stock and want AI B-roll that actually elevates your video, Magic Hour belongs in your stack.

Pricing:
Magic Hour offers a free tier, with paid plans available on its official site.

Submagic

Best for: Social media managers producing high-volume short-form content.

Submagic is built for speed. Upload a video, and it returns a finished clip with captions, emojis, and automatically inserted B-roll in minutes.

In testing, it consistently delivered usable results with almost no manual effort.

Pros

• Extremely fast, minimal setup
  
• Strong caption timing and formatting
  
• Great for short-form platforms
  

Cons

• Limited control over B-roll choices
  
• Can misread nuance
  
• Output can feel similar across videos
  

My take:
Submagic is built around one idea: speed beats control for most social content. And for that use case, it delivers extremely well. You upload a video, and within minutes you have a captioned, emoji-enhanced clip with B-roll already synced to the dialogue.

What stood out during testing is how little friction there is. You don’t need to think about shot selection, timing, or formatting. Submagic makes most of the creative decisions for you, which is exactly why social media managers love it. For high-volume TikTok, Reels, or Shorts workflows, it removes nearly all editing overhead.

The downside is predictability. Because the system is optimized for patterns that perform well, different videos can start to feel similar. If you’re building a strong visual brand or telling nuanced stories, you may find the AI’s choices slightly off or too literal.

Submagic belongs in the top tier because it consistently saves time at scale. If your priority is publishing frequently and staying on trend, it’s one of the fastest paths from raw footage to finished clip.

Pricing:
Paid plans start around $12/month (annual billing).

OpusClip

Best for: Podcasters, educators, and long-form video repurposing.

OpusClip excels at understanding conversation flow. Instead of reacting to isolated keywords, it analyzes context and highlights moments worth clipping, then adds B-roll accordingly.

Pros

• Strong contextual understanding
  
• Excellent for interviews and podcasts
  
• Built-in virality scoring
  

Cons

• Slightly slower processing
  
• Fewer caption styles
  
• UI prioritizes function over aesthetics
  

My take:
OpusClip feels like it was designed by people who actually edit long-form content for a living. Its strength isn’t flashy visuals - it’s understanding conversation structure. The AI identifies moments of emphasis, emotional shifts, and standalone ideas, then builds clips around them.

In practice, this makes OpusClip extremely effective for podcasts, interviews, webinars, and educational videos. Instead of manually scrubbing through an hour-long recording, the tool surfaces multiple usable segments and adds contextual B-roll that supports the message rather than distracting from it.

I found OpusClip especially useful when repurposing content for multiple platforms. The same long video can generate several clips with different framing and pacing, each supported by relevant visuals. This alone can cut editing time by more than half.

It’s not the most visually customizable tool, and processing can take longer than simpler editors. But for creators whose main challenge is turning long recordings into structured short-form content, OpusClip absolutely earns its spot in the top group.

Pricing:
Paid plans start around $15/month (annual billing).

Kapwing

Best for: Creators who want AI help without giving up control.

Kapwing blends AI B-roll suggestions with a full browser-based editor. The AI gives you a starting point, but every clip is editable.

Pros

• Strong balance of automation and control
  
• Full-featured editor
  
• Good collaboration tools
  

Cons

• Slower than one-click tools
  
• No automation API
  
• Performance depends on device
  

My take:
Kapwing sits in the middle ground between full automation and manual editing, which is exactly why many creators stick with it long-term. The AI B-roll feature gives you a solid first pass, but nothing is locked in. Every clip, transition, and timing choice can be adjusted.

During testing, Kapwing felt more like an assistant than an editor replacement. The AI speeds up the early stages - rough structure, initial visuals - while still letting you fine-tune details. This makes it well-suited for creators who want consistency across videos without sacrificing control.

Kapwing also shines in collaborative environments. Teams can comment, edit, and iterate directly in the browser, which reduces back-and-forth and version chaos. For agencies or small marketing teams, this matters more than raw AI intelligence.

It’s not the fastest option, and it won’t generate viral-style edits automatically. But if you want AI help without giving up authorship, Kapwing is one of the safest choices.

Pricing:
Free plan available. Paid plans start around $16/member/month.

VEED.io

Best for: Marketing teams consolidating video tools.

VEED.io combines AI B-roll with subtitles, screen recording, teleprompters, and collaboration. B-roll quality is solid, though not the platform’s main focus.

Pros

• Wide feature set
  
• Strong subtitle and translation tools
  
• Good for teams
  

Cons

• Interface can feel crowded
  
• B-roll AI is competent, not exceptional
  
• Rendering speed varies
  

My take:
VEED.io is less about being the “best” at AI B-roll and more about being good enough at everything. Its B-roll generator works reliably, but the real value comes from having subtitles, recording, editing, and exporting in one place.

In testing, VEED.io made sense for structured workflows: onboarding videos, internal communications, product walkthroughs, and marketing content. You can script, record, add B-roll, subtitle, and export without leaving the platform.

The tradeoff is complexity. For simple edits, the interface can feel heavy. And while the AI B-roll suggestions are solid, they’re not as context-aware as OpusClip or as visually distinctive as Magic Hour.

VEED.io earns its place because of breadth. If your team wants fewer tools and predictable output, it’s a practical, business-friendly option.

Pricing:
Plans start around $9/month.

Vmaker AI

Best for: Professional marketing and product videos.

Vmaker AI is tuned for clean, business-focused output. Its B-roll generator pairs well with templates and structured scenes.

Pros

• Good for demos and explainers
  
• Focused, simple interface
  
  Integrates with Vmaker ecosystem
  

Cons

• Smaller media library
  
• Less suited for viral content
  

My take:
Vmaker AI is clearly optimized for professional, polished output rather than experimentation. The B-roll it suggests tends to be clean, safe, and suitable for product demos, sales videos, and explainers.

What stood out is how focused the experience feels. There are fewer distractions, fewer creative extremes, and more structure. This makes it approachable for teams that don’t want to “learn editing,” but still need presentable videos.

In real-world use, Vmaker works best when paired with scripts and templates. You’re not exploring ideas - you’re executing a message. For marketing teams producing repeatable formats, that’s a strength.

It’s not built for trend-driven content or visual storytelling. But if your goal is clarity and professionalism, Vmaker AI does exactly what it promises.

Pricing:
Starter plans begin around $18/month.

Gling.ai

Best for: YouTubers automating rough cuts.

Gling.ai removes silences, trims mistakes, and adds light B-roll as part of a broader automation workflow.

Pros

• Huge time savings on raw footage
  
• Designed for YouTube creators
  
• Solves multiple editing steps at once
  

Cons

• Aggressive cuts require review
  
• B-roll features are basic
  
• Usage based on processed minutes
  

My take:
Gling.ai isn’t a pure B-roll generator - it’s an automation layer for YouTubers. Its biggest value is removing silence, bad takes, and filler words before you even think about visuals.

In practice, this changes how you edit. Instead of spending hours cleaning up raw footage, you start with a tighter cut. The B-roll feature then adds basic visual support on top of that foundation.

For long talking-head videos, this is a massive time saver. I found it particularly helpful for creators who film frequently and want to stay consistent without burning out.

Gling’s B-roll isn’t as advanced as dedicated tools, but that’s not the point. It earns its place because it attacks the most painful part of YouTube editing - the rough cut - and makes everything else easier.

Pricing:
Plans start around $10/month.

Market Landscape & Trends

AI B-roll tools are splitting into two camps:

• Speed-first tools that automate everything
  
• Control-first tools that assist rather than decide
  

We’re also seeing a shift toward:

• Multi-modal generation (text → video)
  
• Vertical-specific tools (YouTube, marketing, social)
  
• AI-generated footage replacing stock libraries
  

Tools like Magic Hour represent the next phase: fewer stock clips, more generated visuals.

Which AI B-Roll Generator Is Best for You?

• Solo creators: Submagic or Kapwing
  
  
• Podcasters: OpusClip
  
  
• Marketing teams: VEED.io or Vmaker AI
  
  
• YouTubers: Gling.ai
  
  
• Brand-driven visuals: Magic Hour
  
  

The best approach is to test one tool per workflow and compare real output, not feature lists.
