Lazy loading for videos is a performance optimization technique that defers the loading of video content until it's needed. Instead of loading all embedded videos when the page loads, NitroPack ensures they load only when they come into view, significantly improving initial page speed.
By delaying video loading, NitroPack reduces page weight, saves bandwidth, and helps improve Core Web Vitals metrics like Largest Contentful Paint (LCP).
Why does Lazy Loading for Videos matter?
Embedded videos, such as those from YouTube, Vimeo, or self-hosted sources, can significantly slow down a website due to:
Heavy media files requiring large data transfers.
Multiple third-party scripts running in the background.
Increased DOM elements, affecting rendering performance.
With NitroPack’s Lazy Loading, videos load only when they are about to appear on the screen, reducing unnecessary resource usage and improving overall site performance.
How NitroPack’s Video Lazy Loading works
Lazy loading for videos is automatically enabled when you optimize your website with NitroPack.
Detects embedded videos – NitroPack identifies <iframe> and <video> elements on your page.
Replaces them with a lightweight preview – Instead of loading the full video, a placeholder or a thumbnail is displayed.
Loads only when visible – Once a user scrolls close to a video, it automatically loads and plays on demand.
