Product B-roll is supplementary video footage showing a product in use, from different angles, or in lifestyle contexts. It's used to add visual interest and demonstrate product features while the main narrative continues. AI can generate unlimited product B-roll from a single product image.
Product B-Roll Footage
Frequently Asked Questions
What is product b-roll and why does it matter for ads?
Product b-roll is supplementary footage of the product itself — close-ups, packaging shots, in-use demos, before/afters — cut in around the main creator footage. Strong b-roll lifts conversion by 15–30% because it reinforces the product's value prop while the creator is talking. UGC Copilot generates product b-roll automatically from a single uploaded product photo using Nano Banana Pro.
How long should each product b-roll cut be?
1.5–3 seconds per cut, with 2–4 cuts in a typical 30-second UGC ad. Longer cuts feel like a commercial; shorter cuts feel disorienting. The pacing should match the script — every claim in the voiceover gets a corresponding b-roll cut. UGC Copilot times b-roll cuts to script beats by default.
Can I use my own product video as b-roll instead of AI-generated?
Yes. UGC Copilot lets you upload existing product footage and mix it with AI-generated scenes inside the same ad. This is a common pattern for established brands: keep the existing live-action b-roll, generate the creator/persona scenes with AI, and let the platform stitch them together with consistent pacing and overlays.
