AI B-roll generator: the right footage for every line, found for you

Why B-roll changes retention

A single static shot of a person talking is the easiest content to make and the easiest to scroll past. Retention graphs on talking-head clips tend to slide steadily; add a relevant cutaway every four to six seconds and the slide flattens, because each cut gives the eye something new. Editors have known this for decades. The reason most creators skip it is that finding footage is slow: search a stock site, scrub through results, download, import, trim, repeat for every line.

An AI B-roll generator does the search from the script. Splicora reads each sentence, extracts the visual idea in it — "coffee shop", "city at night", "typing on a laptop" — and returns clips that show it. You keep the judgement; the tool removes the searching.

What kind of footage it finds

• Literal matches — the sentence says "morning commute", the suggestions show trains, traffic and coffee.
• Abstract matches — for "growth" or "focus" it offers the visual metaphors stock libraries are full of: time-lapses, close-ups, aerial shots.
• Texture — slow, neutral clips that sit under a long passage without distracting from it.

Every clip comes from the Pixabay library under its free licence, so it can be published on any platform without attribution or a copyright claim.

B-roll and the rest of the edit

B-roll is inserted inside the video editor, where it sits alongside captions, a hook and music from the royalty-free library. On the Pro plan, clips from the AI clip generator can have B-roll added automatically as they are cut, so a whole batch of shorts comes out with cutaways already in place.

How much B-roll is enough

More is not better. A cutaway every four to six seconds keeps a talking-head clip moving; one every second turns it into a slideshow and buries the speaker. Splicora suggests one clip per moment rather than one per sentence, and the timeline makes it easy to remove a suggestion that does not earn its place. A good rule for a 45-second clip: four to seven cutaways, none longer than three seconds, and the speaker on screen for the hook and the last line.

Match the mood as well as the subject. A slow, warm clip under a reflective passage and a fast, bright one under a punchline read as editing; the reverse reads as a mistake. The suggestions come ranked, so the first is usually the closest match, but the preview is there for a reason.

B-roll for faceless and narrated videos

The same engine drives the faceless video generator, where there is no speaker on screen and every beat of the script needs footage. There it runs on every line rather than every few seconds, and it adds a slow push-in to each clip so a static shot never sits still. If you make narrated explainers, that is the tool; if you make talking-head clips, this one.
