Using AI B-Roll Under an Agent Voiceover
AI B-roll beneath an agent voiceover should illustrate the exact statement being made without adding unsupported visual claims. Match each insert to the approved script, verify the source property and review the generated movement before combining it with spoken information.
Break the script into visual needs
Mark the sentences that benefit from supporting imagery and describe what each insert must show. A statement about room connections needs context; a statement about a finish may need a detail. Do not choose footage only by mood. The image and voiceover together can imply more than either one does alone.
Keep the spoken claim and image equally accurate
Verify property facts in the script and compare the generated clip with its source. A true sentence can become misleading when paired with imagery of another property or an invented feature. Label conceptual material clearly and avoid using it under narration that describes the current home as if the proposal already exists.
Coordinate timing and audio space
Provide the intended duration and surrounding sequence so the clip does not force the narration to rush or leave an awkward pause. Keep additional text concise when viewers are also listening to speech. Review muted playback as well, ensuring the clip and any necessary identification still make sense without the voiceover.
Example: explain a living-room connection
An illustrative sentence about the terrace should be supported by a source showing that actual relationship. A generated ocean view unrelated to the room would imply a different property feature. A simple accurate view is more useful than a dramatic insert that changes the meaning of the narration.
Voiceover B-roll plan
- Map each insert to an approved sentence.
- Verify both the spoken fact and visual source.
- Specify timing, orientation and necessary identification.
- Review the combined result with sound and muted.
Frequently asked questions
Can B-roll cover pauses in the agent recording?
It can support editing, but it should still be relevant and accurate. Do not fill a pause with unrelated footage that changes the property's implied story.
Should the agent approve the combined version?
Yes. Reviewing the voiceover and clips separately may miss implications created when they are presented together.
