Video Delivery Patterns

Compare the performance impact of unoptimized video loading versus the modern Video Facade pattern.

Poor Web Vitals

Standard Video Tag

Loads the full video asset immediately on page load and omits explicit dimensions, causing massive layout shifts (CLS) and slow LCP times.

Sloppy Facade

Attempts a facade but ruins Web Vitals via parser-blocking JS, a late-injected banner shifting layout, and main-thread blocking on click.

Video Facade Pattern

Reserves space dynamically using aspect-ratio (0 CLS) and defers loading the heavy video element until user interaction via an optimized WEBP poster.
