AI b-roll generator
B-roll that matches what you say

Generated B-roll from your words
Open Generated B-roll and Voxcene marks the sentences in your transcript that need something to look at, such as a product, a place or a number.
For each line, add one of your own photos or generate a picture made for that sentence. You can skip any you don't need. As the sheet puts it, every one of these is optional.

Insert B-roll, blank clips or AI shots
Have your own footage? Tap + and add a Photo over the video, or open a clip lane and drop in a video cutaway from your phone. A Blank clip gives you a clean colour or gradient for a title or Motion.
If you need a moving shot you don't have, Generate with AI on Premium can make One AI shot. That's a single generated clip, made from a description or a photo, as its own project.

Your own pictures vs generated
Voxcene doesn't come with a stock library. Usually the best b-roll is your own anyway, like your product or your shop, and adding it costs nothing.
When you don't have the shot, generate a picture for that exact sentence. It appears with a slow zoom, so it moves with the video instead of sitting still.
- Your photos and clips: free
- Generated picture: 5 AI credits
- No stock library built in
- Up to 30 pictures per video

FAQ
Questions people ask
What is b-roll?
B-roll is the footage or pictures you cut to while someone keeps talking, like the product they mention or the place they describe. It keeps a talking video moving and shows what words alone can't.
How does Voxcene know where b-roll should go?
It reads your transcript and marks the sentences that would land harder with something to look at. You see every marked line and decide which ones get a picture.
Is the generated b-roll a video clip?
It's a picture, made for that moment, shown with a slow zoom so it doesn't sit still. For your own video b-roll, add a clip from your phone on a clip lane.
Does Voxcene have free stock footage?
No, there's no stock library built in. You can use your own photos and clips for free, or generate a picture for 5 AI credits.
What does it cost?
Generated B-roll is part of AI Studio in Premium. Marking the moments costs 2 AI credits, and each generated picture costs 5. Using your own photos costs nothing.
How many pictures can I add?
Up to 30 pictures per video, and every one is optional.
