What is the difference between these AI b-roll tools?
The biggest difference is who decides where the clips go: the tool or you. The second is which stock library the clips come from.
- Jupitrr and Cutroom place clips on your words for you as soon as you upload.
- Submagic, Captions and BigVU add b-roll along with captions and other automatic edits.
- OpusClip adds b-roll to the short clips it cuts from a long video.
- Descript gives you a stock library, and you drag each clip into place yourself.
- Every tool that adds b-roll for you also lets you change a clip afterwards, from swapping it to moving or trimming it.

Which AI b-roll tool should you choose?
It comes down to where your video starts and how much you want done for you.
Which AI b-roll tool should you choose
Choose Jupitrr if you post a talking video every week and want premium stock clips added the moment you upload.
Choose Submagic if you post many short captioned videos and want b-roll added from $12 a month, with automatic zoom-ins on Pro.
Choose Captions if you film and edit on your phone and want an AI edit that adds b-roll for you.
Choose BigVU if you read from a teleprompter on your phone and want b-roll added after you record.
Choose OpusClip if you start from long videos and want short clips with b-roll already on them.
Choose Descript if you edit long recordings as text and would rather place every stock clip yourself.
Choose Cutroom if you want a video of you talking turned into a finished vertical ad, with a clip on the exact words. Your first video is free.
Where Cutroom fits
Cutroom makes one kind of video: you talking to camera, turned into a finished vertical ad. The b-roll is part of that edit.
- You upload one clip of yourself talking, up to 3 minutes long.
- Cutroom finds Pexels and Pixabay clips for the things you mention and shows each one over exactly those words.
- You can swap any clip, search millions of free ones, or show it full screen, on a small card or in a bottom band.
- It also adds captions in 40 styles and an opening headline. Music is optional.
- Lite costs $19.99 a month for 1,250 credits, and a 30-second video uses 110 of them.
- Your first video is free, with no card, and you have 7 days to make it. It carries a Cutroom mark; Lite removes it.

When you say "your coffee habit", a coffee clip shows over those words.
Questions people ask
- What is the best AI b-roll tool?
- Jupitrr, for talking videos: it adds Getty and iStock clips over your words as soon as you upload. OpusClip is better if you start from a long video. Descript is better if you want to place every clip yourself.
- Which AI b-roll tools are free?
- Captions, OpusClip, Descript and BigVU have free plans, but none of them adds b-roll for you. On Descript's free plan you can place the first 5 stock results of each search yourself. Submagic has a free trial, Jupitrr has no free plan, and Cutroom's first video is free, with b-roll.
- Where does AI b-roll footage come from?
- From stock libraries. Jupitrr uses Getty and iStock. Submagic uses a free library on Starter and Storyblocks, a paid stock library, on Pro. OpusClip uses Pexels and AI-made images and video, and Descript has its own royalty-free library. Cutroom uses Pexels and Pixabay, which are free to use.
- Can I change the b-roll the AI adds?
- Yes, in every tool here. Jupitrr, Submagic, OpusClip and Cutroom let you swap a clip for another, and Submagic and OpusClip also let you change when it starts and ends. In Captions you change details yourself or ask its chat editor.
- Can AI put b-roll on the exact words I say?
- Yes, if the tool works from your transcript. Cutroom shows each clip over the exact words it matches, and Jupitrr matches clips to your script. In a timeline editor you set every start and end point by hand.
- How much b-roll should a talking video have?
- Around half at most. Use b-roll where you describe something the viewer can picture, and keep your face on screen for the rest. Cutroom lets b-roll cover at most 40 to 52 percent of the video, depending on the pace you pick.
- Should I use stock b-roll or film my own?
- Film your own for anything that is yours, like your product, your shop or your hands at work, because stock has no clip of those. Use stock for everyday things like a laptop, a kitchen or a city street.
Upload one clip of yourself talking and see the stock clips added over your words. Your first video is free.
