AI B-roll generator

AI B-roll generator for what your actor says.

RiffAds is an AI B-roll generator that makes new cutaway clips for your video ads: product close-ups, unboxing and lifestyle shots from a text prompt or a product photo, made with Veo 3.1, Kling 3 and more.

The short answer

What is B-roll, and how does AI make it?

B-roll is the supporting footage you cut to while the speaker talks: product close-ups, hands using the product, a lifestyle scene. An AI B-roll generator renders those clips new from a prompt or a product photo. RiffAds does it with models such as Veo 3.1 and Kling 3, instead of pulling stock footage, and shows the credit price before each clip runs.

Best for

  • Cutaways for talking actor ads
  • Ecommerce product close-ups
  • Lifestyle and scene-setting shots
  • Agencies making ad variants
  • AI agents that assemble ads

How it works

  1. 01

    Pick a video model

    In the studio, choose the model for the shot: Veo 3.1, Kling 3, Seedance 2.5, Omni Flash or MiniMax H3 Max.

  2. 02

    Describe the shot

    Write what happens in the scene, and attach your product photo as a reference image or start frame, as the model allows.

  3. 03

    Read the estimate

    Set the length, aspect ratio and resolution, then read the credit estimate before anything renders.

  4. 04

    Cut it in

    Trim the clip, join it with your talking actor clips using Stitch, add captions and download the file.

06FAQ

AI B-roll generator, answered.

Still unsure? Book a call

It covers the lines while the creator keeps talking. In a UGC ad the A-roll is the person speaking to camera, and the B-roll shows what they describe: the product up close, the unboxing, the product in use or the result. Cut to it on each claim, then back to the speaker, so the viewer sees the proof instead of only hearing it.

Yes. Some B-roll tools search stock libraries and drop matching clips on your timeline, but RiffAds uses no stock footage. A video model renders every clip new from your prompt, and you can start from your own product photo as the first frame or a reference, so the clip begins from your real product.

It depends on the shot. Veo 3.1 makes clips of up to 8 seconds at up to 4K, in 16:9 or 9:16, with optional audio. Kling 3 runs 3 to 15 seconds, adds 1:1 and takes a start and end frame. Seedance 2.5 reaches 30 seconds for longer takes. Omni Flash and MiniMax H3 Max are live too, and every plan gets every model.

Keep each clip about as long as the line it covers, then cut back to the speaker. TikTok's creative best practices advise showing your content proposition within the first 3 seconds, so an early product shot helps. RiffAds models make clips from 3 seconds (Kling 3, Omni Flash) up to 30 (Seedance 2.5), and the Trim tool shortens any clip.

B-roll is billed per second of video, and you see the credits before a clip runs. Per second of video, the current rate card lists Veo 3.1 from 35, Kling 3 from 14.7 and MiniMax H3 Max from 8.8 credits. Each credit is $0.01. The cheapest plan costs $49 a month. Credits never expire, and a clip that fails is not charged.

Yes. The RiffAds Terms make you the owner of your workspace's outputs where the law allows, subject to the AI models' own terms, and they allow use in paid ads. Adding any label a platform or law asks for is your job. TikTok requires a disclosure on ads with fully AI-generated video, such as its 'This ad contains AI-generated content' toggle, and rejects or restricts ads that leave it out.

Yes. Every plan includes agent access through the API, MCP, Agent Skills and CLI. An agent can price a clip, pick the model and render it, paid from your studio credits. People set the caps, not the agent: by default one agent job may use up to 600 credits, and an organization's agents 2,000 credits a day.
