How to choose B-roll that actually helps a talking-head video
B-roll is supporting footage shown alongside the main story. The strongest choice answers a visual question: what does this look like, how does it work, or what changed? Start with that question before searching a library or generating a new image.
Give each cutaway a job
Write a short note beside the spoken passage: demonstrate a step, show evidence, establish a place or bridge an edit. If you cannot name the job, the speaker may already be the best picture. A cutaway is not automatically an improvement.
Distinguish evidence from illustration. Footage of the actual dashboard supports a product walkthrough; a generic shot of someone typing does not demonstrate that feature. If a visual is a reconstruction or generated illustration, present it in a way that cannot be mistaken for the real event.
Look through your own material first
Your own screen recordings, work-in-progress shots and close-ups often contain more specific information than stock. Keep descriptive filenames or tags for the subject, action and orientation, and retain the original file alongside any edited derivative.
Create a small selection of reusable assets rather than a giant folder of near-duplicates. Note where you used a shot so the same clip does not appear repeatedly in one video. Avoid including customer names, notifications or private browser tabs in a screen recording.
Narration: ‘I stopped scheduling every spare minute.’ Search idea: ‘productivity.’
Show a fictional calendar with three open blocks remaining after one task is moved. Keep the free space visible while the sentence finishes.
Invented shot plan, not a generated asset. It illustrates the actual change being described without adding unrelated office footage.
Search for an action, not just a topic
‘Planning’ is a vague search. ‘Hand moves a task card from this week to next week’ describes a shot and a purpose. Specify the action, the important object and what the viewer must be able to read or recognize.
For generated visuals, the same brief helps, but inspect results for inaccurate interfaces, impossible objects and misleading details. A plausible-looking image is not verification of a factual claim. Neither a generated image nor a stock subscription automatically establishes every right needed for every use; keep provenance and check the applicable terms.
Place it where the viewer needs the information
Let the viewer identify the subject before the shot ends. For a screen demonstration, give the action enough time to be understood; do not cut away halfway through the only visible explanation. Return to the speaker when expression or personal conviction carries the point.
Listen to the supporting clip’s audio too. An unexpected music bed or room sound can distract from narration. Review its crop in every intended aspect ratio—an important button at the edge of a landscape recording may disappear in a vertical crop.
- The shot supports a specific spoken point.
- The viewer can distinguish real evidence from illustration.
- Important details remain visible after cropping.
- Private information is absent or intentionally obscured.
- Source, permissions and any required attribution are recorded.
