Overall median field LCP is 1.8s for self-hosted media (TTFB 992 ms, load delay 295 ms, load duration 139 ms, render delay 213 ms) versus 2.0s for CDN-hosted media.

Media hosting source or the framework

Why streaming large video files from the primary origin saturates LCP bandwidth
Unlike small images or fonts, a single hero <video> file often weighs several megabytes. Serving heavy MP4/WebM streams from the same origin (87.2% of media-using sites, 6,698) can saturate origin bandwidth and contend with critical CSS and hero poster images, resulting in 74% good LCP (1.8s median). Offloading video streams to a dedicated media CDN (14.5% of media-using sites, 1,117) lifts good LCP to 71% (2.0s median).
Understanding video and audio hosting sources
Offload background MP4/WebM videos to a dedicated media CDN (Cloudflare Stream, Bunny Stream, or Jetpack VideoPress) and always set an optimized poster="" image on <video> tags. On WordPress, 87.2% of media-using sites serve video directly from their origin (74% good LCP, 1.8s median).
