The Best AI B-Roll Generators in 2026 (Stock-Matched vs AI-Generated Footage)

The best AI b-roll generators in 2026 split into two kinds. To add b-roll to a talking video automatically, pick Vidpal AI Auto B-rolls, which reads your transcript and places Pexels, Pixabay and Vidpal-library clips on matching sentences inside a full editor (from $19 a month), or Opus Clip (from $15) or Submagic (from $19). To create new shots from a prompt, use Runway Gen-4.5 (from $12 a month billed yearly), Kling 4.0, Luma, Pika, Google Veo 3.1 or Adobe Firefly, whose Firefly-model videos Adobe calls safe for commercial use. Sora is no longer available. We checked every price on the vendor's own site on November 11, 2026.

This guide is for creators, coaches and marketers who talk to camera and want cutaway footage without hunting through stock sites, and for anyone weighing a video model instead. It compares seven auto b-roll inserters and six generative models in two tables, then covers licensing and AI labels, stock versus generated footage, the cost of one minute of b-roll, and common mistakes. In Vidpal, AI Auto B-rolls sits inside the AI Editing editor, so b-roll, zooms, captions and publishing happen in one project.

What Is an AI B-Roll Generator?

An AI b-roll generator is software that supplies the cutaway shots laid over your main footage, and the phrase covers two different products. The first is an auto b-roll inserter: it transcribes a talking video, finds sentences that need a visual, and places matching stock clips (sometimes AI images or generated clips) on the timeline. Vidpal, Opus Clip, Submagic, Kapwing, Descript, Captions and CapCut belong here. The second is a generative video model: you type a prompt or upload a still, and it renders a new shot that never existed, usually 5 to 10 seconds long. Runway, Kling, Luma, Pika, Google Veo and Adobe Firefly belong here.

An inserter works on a finished recording and saves editing time. A generator gives you raw shots that you still place by hand, and it bills per second of footage. Many creators use both: an inserter for the moments a stock library covers, and a generator for the one shot no library has.

How We Compared These Tools

We compared published features, limits and prices. For inserters: b-roll source, swappable placements, which plan includes it, the free plan and the entry price. For generators: current model, longest clip per generation, resolution, starting price and published commercial-use terms. Every competitor fact comes from the vendor's own pricing, product or help page, opened on November 11, 2026; where a vendor did not publish a number, we say so.

• B-roll: secondary footage cut over your main shot (the A-roll) to illustrate a point or hide a jump cut.
• Auto b-roll: a feature that reads the transcript and places clips on matching sentences without you searching.
• Text-to-video and image-to-video: models that render a new clip from a prompt, or from a still you upload.
• Credits: the unit most AI tools bill in; video models usually charge credits per second of output.
• Content credentials (C2PA): metadata that marks a file as AI-generated, which platforms read to apply a label.

Which AI Tool Adds B-Roll to a Video Automatically?

Vidpal AI Auto B-rolls, Opus Clip, Submagic, Kapwing, Descript and Captions all read your transcript and place b-roll for you. CapCut gives you a stock library and an AI video generator, but we found no CapCut page documenting automatic placement. Here is how the inserters compare, as of November 11, 2026.

Vidpal AI Auto B-Rolls: Best Pick for Adding B-Roll to Talking Videos

Vidpal AI Auto B-rolls is built for one job: putting relevant cutaways over a video you recorded yourself. You upload the video to AI Editing (up to 10 minutes and 2 GB), Vidpal transcribes it with automatic language detection, and AI Auto B-rolls reads the transcript and places stock clips from Pexels, Pixabay and Vidpal's own library on the sentences that match. It avoids repeating a clip within one video. Every placement stays editable: swap it through a stock search, replace it with your own upload, or generate an AI image for a moment where no stock clip fits.

The b-roll is one tool in a full editor. The same project adds AI Auto Zooms, Remove Silences, Remove Filler Words, Smooth cuts, AI Sound Effects, captions from 75 presets, and Aspect Ratio with Smart Reframe to turn a landscape recording into 9:16. Then you post to Instagram, YouTube, TikTok and LinkedIn from the Publish panel, or schedule up to 90 days ahead, on Pro and Business. For faceless videos, Vidpal Studio picks b-roll per scene from stock footage or AI images. The AI b-roll generator page shows examples.

Step 1: Upload your talking video to AI Editing (1 credit).

Step 2: Turn on AI Auto B-rolls, review each placement and swap any clip that misses its sentence.

Step 3: Add zooms and a caption preset, export in 1080p (1 credit), then post or schedule it.

The credit math: a 6-minute talking video costs 2 credits, 1 at upload and 1 at export, however many b-roll clips it contains. Starter costs $19 a month, or $12 a month billed annually, for 15 credits, enough for 7 finished videos. Pro costs $39 a month, or $23 billed annually, for 40 credits (20 videos) and adds publishing and 2K export. Business costs $69, or $41 billed annually, for 100 credits and 4K export.

AI Auto B-rolls places existing footage and images; it does not generate new video clips from a prompt, and the only generated video in Vidpal is an optional hook clip of about 5 seconds in Studio. Videos longer than 10 minutes go through AI Clips instead.

Start free with Vidpal: the Free plan's 4 one-time credits render Auto Reels and Image Posts with a watermark, and exporting AI Editing videos with b-roll starts on Starter.

Opus Clip AI B-Roll: Best for Clips Cut From Long Videos

Opus Clip cuts long videos into short clips, and its AI B-roll adds footage to those clips. Per Opus Clip's AI B-roll page, it adds relevant footage from Pexels, you can upload your own, and in Custom mode you pick a sentence to generate b-roll for. Stock clips can be dragged and trimmed but not extended past the original footage; AI b-roll can be regenerated from a revised prompt. On Opus Clip's pricing page, Starter costs $15 a month with 3 AI image and 3 stock b-roll clips a month, and Pro costs $29 a month with unlimited stock b-roll, 50 AI image clips a day and AI video b-roll. The free plan has no b-roll.

Submagic: Best for Short Captioned Clips

Submagic's Magic B-rolls reads your transcript and inserts stock b-roll where it fits, or you add a clip to any subtitle line, then set its timing, size, style and position. Submagic's pricing page lists Starter at $12 a member a month billed yearly, shown against $19 monthly, for 15 videos of up to 2 minutes with free b-rolls. Pro is $23 billed yearly, a $192 yearly saving that implies $39 monthly, for 40 videos of up to 5 minutes with Storyblocks b-rolls and auto zooms. Business is $41 billed yearly for 100 videos of up to 30 minutes. No free plan is listed.

Kapwing: Best for Stock and Generated B-Roll in One Project

Kapwing's AI B-roll Generator analyzes your transcript and places stock footage from iStock, Pexels and Pixabay at key moments; you can swap, trim or remove each clip. You can also generate a clip from a text prompt with models such as MiniMax, Veo and Seedance and add it yourself. The free plan exports up to 4 minutes at 720p with a watermark and includes 10 AI credits. Kapwing's help center prices Pro at $16 per member a month billed annually or $24 billed monthly, with 1,000 credits, and the Kapwing pricing page lists Business at $50 with 4,000 credits.

Descript: Best for B-Roll Inside a Transcript Edit

Descript handles b-roll through Underlord, its AI co-editor: you ask for b-roll, and it finds stock or media-library footage, or generates it, and previews options before adding them. On Descript's pricing page, Free gives 1 media hour a month at 720p with a watermark and the first 5 stock search results. Hobbyist costs $24 a month, or $16 billed annually, with 10 media hours, 400 AI credits and the first 12 stock results. Creator costs $35, or $24 annually, with 30 media hours and unlimited stock. Generated video is listed on every paid plan.

Captions and CapCut: Phone-First Options

Captions runs on iOS and the web. Its AI Edit cuts silences and filler sounds, adds captions, and adds b-roll you import or b-roll Captions generates, which uses more credits, per its help center. Captions' pricing page lists Max at $24.99 a month (iOS price) with 500 credits; the free plan has a limited feature set and no AI credits.

CapCut has an in-app stock library and an AI video generator, but we found no CapCut page documenting automatic transcript-based b-roll placement, so you place clips yourself. CapCut's pricing page lists a free plan and Pro at $19.99 a month or $179.99 a year.

Which AI Video Generator Makes the Best B-Roll Shots?

For new footage from a prompt, the main options in November 2026 are Runway Gen-4.5, Kling 4.0, Luma Ray3.2, Pika, Google Veo 3.1 and Adobe Firefly. Sora is not on the list: the OpenAI help center says the Sora app and web experience were discontinued on April 26, 2026 and the Sora API on September 24, 2026. Our Sora alternatives guide covers the switch.

Runway: Best for Directed Cinematic Shots

Runway Gen-4.5 generates 2 to 10 seconds per clip at 720p, and Runway's help center says outputs can be upscaled to 4K. Runway's pricing page gives Free 125 one-time credits; Standard is $12 a month billed annually ($15 regular price) for 625 credits, which Runway says equals 52 seconds of Gen-4.5; Pro is $28 billed annually for 2,250 credits, or 187 seconds. Partner models such as Kling 4.0 run on the same credits. Runway's usage-rights help article says you own what you generate, with no non-commercial restriction, on every plan.

Kling: Best for Longer Single Shots

Kling 4.0 generates 3 to 30 seconds in a single pass and can extend a video to about 2 minutes in total, per Kling's Kling 4.0 page, which also lists 1080p and 4K output for Kling 4.0 as coming soon. Kling's plan pages list Standard at $10 a month before first-month discounts, with 660 credits, and Kling's plan guide says content made on the free Basic tier is not for commercial use while paid plans are. Pick Kling when you need a single shot longer than the 5 to 10 seconds most models produce.

Luma: Best for Polished Look Shots

Luma's Dream Machine runs Ray3.2 and Ray3.14, which make 5- or 10-second clips. The cost table on Luma's pricing page lists 720p at 100 credits for 5 seconds and 1080p at 1,200 credits for 10 seconds. Plus costs $30 a month, or $25 billed yearly, for 10,000 credits and lists commercial use; Pro is $90, or $75 yearly, for 40,000 credits. No free plan is listed. Plus covers about eight 10-second clips at 1080p a month.

Pika: Best for Cheap, Quick Filler Shots

Pika's pricing page lists a Free plan with no watermark but no commercial license, Starter at $10 a month or $8 billed yearly for 600 credits with commercial use, and Creator at $35, or $28 yearly, for 2,600 credits. Every clip in its cost table is 5 seconds: Pika 2.5 at 720p costs 20 credits, Pika H3 Flex at 768p costs 10, and partner models such as Kling 4.0 reach 1080p at 118 credits. Pick Pika for stylized filler shots on a small budget.

Google Veo 3.1: Best for Shots With Native Sound

Google's Veo 3.1 makes 8-second clips with natively generated sound at 1080p and 4K, and every Veo video carries a SynthID watermark, per Google DeepMind's Veo page. You reach it through the Gemini app and Google Flow. On Google's AI plans page, Google AI Pro ($19.99 a month) includes 1,000 Flow credits and a limited trial of Veo 3.1 Lite, and Google AI Ultra (from $99.99) includes Veo 3.1 with 10,000 or 25,000 Flow credits. The plans page does not state commercial-use terms.

Adobe Firefly: Best When Commercial Safety Is the Question

Adobe's AI video generator page says videos made with the Adobe Firefly model are safe for commercial use, and that the model is trained on licensed content such as Adobe Stock plus public-domain content. Partner models inside Firefly (Veo 3.1, Luma Ray3, Kling 3.0, Runway Gen-4.5) may have different terms. Most models make clips of up to 8 seconds, some up to 15, as MP4 at up to 4K. Firefly Free has a daily allotment; Standard is US$9.99 a month for 2,000 credits and Pro US$19.99 for 4,000, per Adobe's Firefly video page.

Can You Use AI-Generated B-Roll Commercially?

Usually yes, but the terms come from each tool and plan. For stock, the Pexels license lets you use and modify footage for free without attribution, but not sell unaltered copies, imply endorsement by people or brands shown, or show identifiable people in a bad light. Pixabay's content license summary adds that content showing recognisable brands can't be used commercially in relation to goods and services. For generated footage, Runway allows commercial use on every plan, Kling and Pika exclude their free tiers, Luma lists it from Plus, and Adobe calls Firefly-model videos safe while noting that partner models differ.

Platform AI labels apply to realistic generated footage, not to real stock clips. YouTube requires creators to disclose AI-generated or altered content that seems realistic, and its own example is AI-generated extra footage of a real place (YouTube Help); clearly unrealistic scenes don't need it. TikTok requires a label on AI-generated content showing realistic scenes or people and reads C2PA content credentials to label uploads automatically (TikTok community guidelines). Meta requires disclosure of photorealistic video or realistic-sounding audio that was digitally created or altered (Meta's labeling announcement). Our guides to AI content labels and copyright rules for short-form video go deeper.

Is Stock B-Roll or AI-Generated B-Roll Better?

Stock b-roll is better for most talking videos, and generated b-roll is better for shots that don't exist. Stock wins for common subjects (a city street, hands typing, a stack of invoices), real places, zero labeling questions and dozens of cutaways with no per-second cost. Generated footage wins for specific or impossible shots (a product concept, a historical scene, a visual metaphor), one consistent style across a series, or an empty stock search.

A practical rule: fill the video from stock first, then generate only the two or three shots stock could not match. In Vidpal, the fallback for a missing match is an AI image; for a moving shot, generate a clip in a video model and upload it into the same placement. For faceless channels, see our list of free stock footage sites for faceless videos and the guide to adding an AI-generated hook clip to a Short.

How Much Does AI B-Roll Cost per Minute?

Inserters bill per video and generators bill per second. Here is one minute of b-roll in a 6-minute talking video, at prices checked on November 11, 2026.

Vidpal: the whole video costs 2 credits (1 at upload, 1 at export), whether it holds 10 b-roll placements or 30. On Starter at $19 a month for 15 credits, a credit costs about $1.27, so the video costs about $2.53; on annual Starter ($144 for 180 credits) it costs $1.60.

Runway Gen-4.5: 60 seconds at 12 credits a second is 720 credits, more than Standard's 625. On Pro ($28 a month billed annually for 2,250 credits), 720 credits cost about $8.96 if every take is a keeper, or about $27 if you keep one take in three.

Pika 2.5: 12 five-second clips at 20 credits is 240 credits, 40 percent of Starter's 600, so about $4 a minute at 720p. Luma Ray3.2 at 1080p: 6 ten-second clips at 1,200 credits is 7,200 credits, 72 percent of Plus, so about $21.60 of a $30 month.

So stock insertion costs a few dollars per video, while generated b-roll runs about $4 to $27 per minute before you place a clip. To try the stock-first approach on your own footage, start free with Vidpal and move to Starter when you are ready to export.

How to Choose an AI B-Roll Tool

• Pick Vidpal if you record talking videos of up to 10 minutes and want transcript-matched b-roll plus zooms, captions, silence removal and publishing to Instagram, YouTube, TikTok and LinkedIn from one credit pool.
• Pick Opus Clip if you mostly cut long recordings into clips and want b-roll on each clip.
• Pick Submagic if your videos are captioned clips of 2 to 5 minutes and you want Storyblocks footage.
• Pick Kapwing or Descript if a team edits in the browser or by transcript.
• Pick Runway for directed cinematic shots, or Kling if single shots longer than 10 seconds matter.
• Pick Pika if the budget is tight, and Adobe Firefly if a client asks how the model was trained.

Common Mistakes With AI B-Roll

• Covering every sentence. Keep your face on screen for the hook and the key claims.
• Accepting literal matches. A sentence about cutting costs can pull a clip of scissors, so review every automatic placement.
• Paying per second for generic shots. Use stock for city streets and keyboards; generate only what stock lacks.
• Skipping the label. Realistic generated footage of real places or people needs a disclosure on YouTube, TikTok and Instagram.
• Ignoring free-plan terms. Kling's free tier and Pika's free plan exclude commercial use.

Getting Started With Vidpal AI Auto B-Rolls

Compare plans on the Vidpal pricing page, and read how an AI video editor differs from an AI video generator.

Frequently Asked Questions

What is the best AI b-roll generator in 2026? It depends on which kind you need. For adding b-roll to a talking video automatically, Vidpal AI Auto B-rolls places transcript-matched clips from Pexels, Pixabay and its own library, from $19 a month, with Opus Clip and Submagic as alternatives. For generating new shots from a prompt, Runway Gen-4.5, Kling 4.0, Luma Ray3.2, Pika, Google Veo 3.1 and Adobe Firefly lead as of November 11, 2026.

How do I add b-roll to a video automatically with AI? Upload the video to an auto b-roll tool, let it transcribe the speech, and turn on its b-roll feature; it places matching stock clips on the sentences that need a visual. In Vidpal AI Editing, AI Auto B-rolls does this for uploads of up to 10 minutes, and every placement can be swapped for another stock clip, your own upload or an AI image.

Does Vidpal generate AI video b-roll? No. Vidpal AI Auto B-rolls places existing stock clips from Pexels, Pixabay and Vidpal's own library on matching sentences, and it can generate an AI image for a moment when no stock clip fits. The only generated video in Vidpal is the optional hook clip of about 5 seconds in Studio, which costs 1 extra credit, charged only on success.

How much does Vidpal cost for adding b-roll? Vidpal AI Editing costs 1 credit at upload and 1 credit per export, however many b-roll clips the video contains. Starter is $19 a month, or $12 a month billed annually, for 15 credits; Pro is $39 a month, or $23 billed annually, for 40 credits and adds publishing. The Free plan cannot export AI Editing videos.

Is AI-generated b-roll safe for commercial use? It depends on the tool and the plan. Runway says you own outputs on every plan, Luma lists commercial use from its $30 Plus plan, Pika's free plan excludes a commercial license, Kling's free Basic tier is not for commercial use, and Adobe says Firefly-model videos are safe for commercial use, as of November 11, 2026.

Do I need to label AI-generated b-roll on YouTube, TikTok or Instagram? You need to label realistic AI-generated footage. YouTube requires disclosure of realistic altered or synthetic content, such as generated footage of a real place; TikTok requires labels on realistic AI scenes or people; Meta requires disclosure of photorealistic video that was digitally created or altered. Real stock footage and clearly unrealistic scenes don't need a label.

Is Sora still available for making b-roll? No. OpenAI's help center says the Sora app and web experience were discontinued on April 26, 2026 and the Sora API on September 24, 2026. For generated b-roll, current options include Runway Gen-4.5, Kling 4.0, Luma Ray3.2, Pika 2.5, Google Veo 3.1 and Adobe Firefly.
