AI B-roll generator, stock or your own footage: when each fits

AI B-roll comes from three main places: a model generates it, a stock library supplies it, or a tool picks it from footage you filmed. Which to use depends on whether the viewer needs to see the real thing. If not, generated or stock is quick and often right. If so, it has to be yours.

I'm Kyle. I built a tool of the third kind, so I have a stake. I did not test the other tools for this page. Each fact about them is from the vendor's own page or request board, read 2026-10-04 and linked beside it.

The three sources

Scroll sideways to see all three columns.

Topic Generated Stock Your own footage
Where the picture comes from A model makes a new clip or image from your prompt or script. A library of clips other people filmed, matched to your words. Clips you filmed. A tool picks among them, or you do.
Good for An idea no camera could catch, or a scene you cannot go back to. Everyday scenes you never shot, when speed matters more than an exact match. What the viewer should take as real: you, your place, your product, your event.
The catch Only as close as your description, and not footage of you. Anyone can license the same clip, and the people in it are strangers. You must have filmed it. A line with no matching shot gets no B-roll.
Check before you post What your plan allows in a commercial video. The license of the library behind the tool. That the people in your clips agree to be shown.
Examples Captions makes a shot from a typed prompt. HeyGen makes cutaways from a script. BRoll Creator keeps clips in one visual style. VEED places generated images on its timeline (read 2026-10-04). OpusClip adds Pexels clips in one click. Submagic matches clips to your transcript. Kapwing draws on iStock, Pexels and Pixabay, and you can swap any clip on its timeline (read 2026-10-04). RawCut cuts only from clips you filmed (read 2026-10-04). Eight more are in my roundup. Takehound is mine.

When a generator or stock is the right call

  • You have no footage of the subject. Either
  • You are showing an idea, not a thing: a mindset or a market. Generated
  • You post often, and speed matters more than an exact match. Stock
  • You want to finish in one browser editor. Takehound cannot do that. Either

Runway's guide draws similar lines: AI-selected stock where speed matters more than a perfect match, generation for shots stock never has (read 2026-10-04).

My view, for coaches and solo creators

When your own footage is the right call

  • You are what the buyer pays for, so the video should look like the person they will meet.
  • You are talking about something you already filmed: a retreat, a workshop, your product.
  • You have no shot of the thing? Then use stock, a generated clip, or stay on camera.

Vizard Agent's how-to rates a clip you shot of the actual subject above a stock clip that only resembles it (read 2026-10-04).

People have asked for the third kind

On two vendors' public request boards, people ask for the automatic picker to use their own clips.

These are small numbers. They show the question comes up, not how often.

What reading these tools' pages showed

  1. On the seven tool pages in the table, “AI B-roll” means stock or generated footage.

    All seven pages in the table's first two columns lead with stock or generated footage (read 2026-10-04). They were chosen as examples of those two kinds, so that is what they show. The own-footage tools are in my roundup.

  2. On some tools, your own clips are a by-hand step.

    Submagic's and VEED's pages describe your own clips as something you add or swap in yourself (read 2026-10-04). The roundup lists tools that do the picking.

  3. Some tools say when nothing fits.

    Takehound does, and so do others. RawCut's page says the app tells you when none of your clips suits a line (read 2026-10-04). The roundup's table has a “When nothing fits” column.

The tool I built

Where Takehound sits

Takehound is mine, so weigh this part. It does the third kind only: no stock, nothing generated.

You paste a script in a desktop browser and point it at a folder of footage you filmed. For each line it can, it picks one of your shots and gives a one-line reason. Where nothing fits, the line stays on you.

You get a B-roll timeline (an FCPXML file) for DaVinci Resolve or Final Cut. Not Premiere, not a finished video. The Mac command-line version takes a talking head you already recorded.

Questions

Can an AI B-roll generator use my own footage?

Some can. Vizard Agent's how-to says it uses your own material first when you give it some (read 2026-10-04). My roundup compares nine tools that work with clips you filmed. Takehound, which I built, uses only footage you filmed.

Can I use generated or stock B-roll in a commercial video?

Look for the license line. HeyGen's page says paid plans include commercial rights to what you generate. OpusClip's page says its stock is copyright free on paid plans, with commercial use under Pexels' guidelines (both read 2026-10-04).

When should I use my own footage, not stock or generated B-roll?

When the viewer needs to see the real thing. Runway's guide says to plan B-roll into the shoot when it has to be “verifiably real”, such as a property for sale (read 2026-10-04). For an abstract idea, stock or a generated clip fits and Takehound does not.
