Why this matters for the Core Web Vitals, and where to start fixing it

When audio or video is present, it outweighs everything else on the page. An autoplaying background video competes with the LCP image for bandwidth at the worst moment, and on phones it burns data the visitor never asked for.

A poster image carries the experience until the visitor opts in. It loads like an image, it can be the LCP candidate, and the video starts on interaction. Autoplay hero video is the expensive way to do what a good photo does.
