B-Roll Overlay
B-roll overlay is supplementary footage layered on top of the primary clip to illustrate what's being said, fill visual dead time, or hide cuts.
Talking-head clips suffer from visual monotony — the same face for 60 seconds rarely holds a viewer to the end. B-roll overlay drops in cutaways: a related news headline screenshot, an explanatory chart, a stock clip, or footage of the thing being discussed. The overlay covers the bottom or upper third of the frame, or fills the screen entirely for 2-4 seconds.
The rule of thumb circulating in clipper communities: one b-roll moment every 7-10 seconds keeps retention measurably higher than a static shot. Hubspot's 2024 video report found short-form clips with at least one b-roll cutaway retained 22% more viewers past the 50% mark.
AutoClip's b-roll feature pulls relevant Pexels and Pixabay clips matched to the transcript. A clip about "NBA finals" gets sourced game footage, a clip about a stock crash gets a candlestick chart. Output is auto-trimmed to the line being delivered.
