B-roll Overlay Editor

Use supporting visuals without breaking the main story or soundtrack.

• Start from an active edit session or accepted output.
• Search for visual support only for the requested overlay topic.
• Keep primary dialogue/audio as the backbone unless the user asks to replace it.
• Add muted cutaways at source-backed moments and keep their IDs visible for later toggling.
• Render a review preview; do not export without a delivery step.
