Fill the gap in your edit
AI B-Roll Generator
Use the AI B-roll generator when an edit needs a short view of a place, a detail, or a pause between ideas. Generate 5–15 seconds from text or an image, then put the selected footage into your own timeline.

The inserts support spoken information while the narration continues in your editor. Use this arrangement to plan where a desk view and a fabric detail would help the viewer follow the explanation.

Find the missing information before writing a prompt
Play the edit up to the gap. If the speaker introduces a workspace, a view of a desk can help establish the setting. If the next line mentions woven fabric, a detail shot can give the viewer something specific to examine. Choose the insert because of the neighboring sentence, rather than because an attractive clip happens to be available.
The AI B-roll generator is useful for creating that individual insert. It does not listen to your full video, find the gap, or choose the cutting point. Keep those editorial decisions in your existing workflow, where you can hear the narration and see both adjacent shots together.
B-roll generally supports the main footage with additional visual information. Adobe's introduction to B-roll describes this relationship between primary and supporting shots. On this page, the practical question is which short scene would clarify the specific edit you already have.
Environment: place the viewer in the scene
An establishing insert needs enough context to locate the main subject. For a workspace explanation, show a desk and part of the room before moving into details. Keep the movement quiet enough that the viewer can read the setting while listening to the line it supports.
An opening view of a workspace
A quiet desk beside a window. An open cream notebook, a dark wooden pencil and a glass of water rest on an oak surface. Soft morning light. The camera moves slowly toward the notebook in one continuous shot. No people, legible writing, subtitles or speech.
5 seconds, 768P, 16:9. Place the usable section beneath your introduction in an external editor.
Use this promptIf your main footage shows a particular room, an invented desk may create a continuity problem. Use a still image from your own setting as the starting point instead, or make the illustrative nature of the insert clear. The AI B-roll generator should not be used to imply that a generated location was filmed for a documentary.
Detail: give one spoken point a visible counterpart
Move closer only when the detail explains something. A fabric insert can draw attention to weave and surface texture while the speaker discusses appearance. It cannot prove a fiber composition, a durability claim, or a result from a material test. Keep the narration tied to information you can support independently.
A closer view of fabric and buttons
The camera gently moves closer to the shirt fabric and visible buttons. Preserve the stripe spacing, seams, cuffs and overall garment shape. No change of clothing, people, hands, text or speech.
Use with your own shirt photograph in Image to Video. Compare the pattern and garment details during playback.
Use this promptWatch the pattern during playback. If the weave changes or the folds shift without a clear cause, use a shorter valid section only if it still supports the edit honestly. Otherwise revise the request or use photographed material. The AI B-roll generator provides a candidate clip; suitability depends on what the shot is meant to show.
Cutaway: make room between ideas
A brief street view can mark a change of place or give an edit a moment to settle. It works best when the surrounding content explains why the viewer is looking outside. If nothing connects the scene to the narration, the insert can distract from the point instead of giving it room.
Describe a single, continuous action, such as light rain on a quiet pavement, rather than a complete sequence of people arriving and departing. A cutaway often benefits from movement that is already underway when it begins. That lets you choose an insertion point without waiting for a story event to start.
Keep generated street footage illustrative unless you have a sound basis to identify a real place. The AI B-roll generator cannot turn an imagined scene into evidence that an event occurred. For factual coverage, use footage whose origin and relationship to the story you can establish.
Choose the input that matches what must carry across the cut
Start the AI B-roll generator from text for a new illustrative setting. Use an image when the next shot should begin with a visible object or composition you already have. Both routes create a separate short clip; neither reads the rest of your project or guarantees continuity with it.
| Starting point | What you control | Useful check |
|---|---|---|
| Text description | Describe the scene and motion, then choose an available aspect ratio. | Does the invented composition fit the surrounding edit? |
| Your reference image | Upload a JPEG, PNG, or WebP within 20 MB and write a motion prompt. Ratio follows the image. | Do recognizable details stay suitable throughout the clip? |
Open Image to Video for the second route. For more help describing a scene from scratch, the text-to-video workspace explains subject, action, setting, and camera choices before you return to the editing decision here.
Review an AI B-roll generator clip inside the edit
Watch the insert at its intended size, with the narration playing. A detail that looked clear on a large preview may be hard to read in a smaller finished frame. If the viewer has only a short pause to notice it, choose a simpler view or let the shot stay a little longer. Timing comes from the sentence and the visual information together.
Keep a small amount of usable footage on both sides of your planned cut when possible. Those extra frames let you move the edit point without immediately generating again. If a clip from the AI B-roll generator contains one distracting moment, evaluate the remaining portion in context. Trimming helps only when the shorter insert still does the job you identified before writing the prompt.
The AI B-roll generator offers 5–15 seconds at 480P or 768P. You can use a shorter portion in your edit. A five-second generation at 768P uses 40 credits, so start there for a restrained action unless the shot needs more time to develop. Longer duration adds cost as well as footage to inspect.
Ask for a settled beginning and ending when those would help your transition. Leave space around the subject if a crop is likely. After downloading, compare camera direction, light, color, and shot size with the clips on either side. A matching subject alone does not make two shots feel connected.
Will the AI B-roll generator put the clip into my video?
No. The AI B-roll generator creates footage that you download and place in your own editor. The diagram above explains a possible arrangement; it does not upload, analyze, or edit your existing video.
How can adjacent shots look more consistent?
Give the AI B-roll generator repeated concrete choices such as light direction, camera height, background simplicity, and movement speed. Use a reference image when a particular subject must carry across. Then compare the results in the actual timeline and adjust your selection or edit as needed. Consistency still needs visual review.
