Automatic B-roll
Automatic B-roll that lands on the line you say it.
Bang AI places your B-roll for you with spoken overlays (Ultimate). Add your product shots, logos and discount codes once. While you film, say “overlay” and what you want, like “overlay serum bottle”. The auto edit drops that shot on that line, and the cue itself never plays. It uses your own shots, not stock footage, so every overlay is your product.

Say “overlay”. Press Auto Edit. Done.
You never drag a clip onto a timeline.
- Add your overlays onceYour product shots, logos and discount codes, added once.
- Say it while you film“This serum fixed my skin in two weeks. Overlay serum bottle.” Keep talking.
- Press Auto EditThe shot shows up on that line, the cue is cut out, and the rest of the edit is done too.
Spoken overlays and B-roll layers
This serum fixed my skin in two weeks. Overlay serum bottle. And here’s my code. Overlay discount code.
This serum fixed my skin in two weeks. Serum bottle And here’s my code. Discount code
Placed for you (Ultimate)
- Your product shots, on the line you name them
- Logos and discount codes, right when you say the price
- The spoken cue cut out, so viewers never hear it
- The ums, pauses and false starts cut in the same pass
Placed by you (Pro)
- B-roll on layers in the Mac app, anywhere you like
- Screen recordings or close-ups over your take
Who Bang AI isn’t for: it places shots you add, it doesn’t find stock clips or make footage up. If you want an app to pick stock B-roll for you, it’s the wrong app, and we’d rather tell you now.
Which shots make good overlays
Spoken overlays place only the shots you add, so it pays to film good ones.
Good overlays
- A close-up of the product you’re naming
- Its texture, the inside, or the thing working
- Your discount code, big enough to read
- Your logo, for the line where you say the brand
Leave these out
- Shots that don’t match what you say on that line
- Footage the viewer has seen in a hundred other videos
- So many overlays your face is never on screen
- Shots of a product you aren’t talking about
Three rules for calling an overlay
- Finish the line firstSay the whole sentence, then “overlay” and the shot. It lands on the line you just said.
- Add it before you filmThe edit places the shots, logos and codes you’ve added, so add every one before you call it.
- Say it clearlyIt cuts by what you said, so say the cue as clearly as the line before it.
How to film your own B-roll
Ten minutes of close-ups covers a lot of videos, since every overlay you add can be called again.
- Film it where you film yourselfSame room, same light, so the shot looks like part of the same video and not a cutaway from somewhere else.
- Get closeFill the frame with the product: the label, the texture, the moment it does its job.
- Hold each shotA few steady seconds per shot, so it reads on screen when it lands on your line.
Where B-roll belongs in a talking video
A spoken overlay lands on the line you call it, so where you say the cue is where the shot goes.
- On the claimShow the product the moment you say what it does, so the viewer sees the proof as they hear it.
- On the codePut the code up as you say it, so nobody has to scroll back to find it.
- Not on the hookKeep your face on the first line. People decide whether to stay on a person, not on a product shot.
Questions, answered.
Can an app add B-roll to my video automatically?
Yes. On Ultimate, Bang AI’s spoken overlays do it: add your shots once, say “overlay” and what you want while you film, and the auto edit drops it on that line.
Does Bang AI use stock footage?
No. It places the product shots, logos and codes you add, so every overlay is yours.
Will viewers hear me say “overlay”?
No. The auto edit cuts the cue out, so only the shot shows up.
Can I move an overlay after the edit?
Yes. Fix any overlay or cut by hand in the Mac app. On Pro you can also put B-roll on layers yourself.
Can I call more than one overlay in a video?
Yes. Say “overlay” and the shot after each line you want one on, like the bottle on one line and your code on the next.
How many overlays should one video have?
As many as the points that need proof, and no more. One shot per claim keeps your face on screen for the rest, which is what keeps people watching.
Which plan has automatic B-roll?
Spoken overlays are on Ultimate. On Pro you put B-roll on layers yourself in the Mac app, and Starter has the full auto edit without B-roll.
Is Bang AI on the App Store?
Yes. Get Bang AI on the App Store for iPhone, which films with a teleprompter that scrolls your script, with a countdown. It’s on the web and the Mac too.
Every video you don’t post is money you don’t make.
