## Beschreibung

**VidDefer – Deferred Video Embeds** replaces heavy video embeds with lightweight
thumbnail placeholders. The real video only loads when a visitor clicks (or scrolls
to) it — saving hundreds of kilobytes per page load.

#### Supported Sources

 * **YouTube** — replaces iframes with thumbnail + play button
 * **Vimeo** — replaces iframes with thumbnail + play button
 * **Self-hosted videos** — replaces `<video>` elements (MP4, WebM, OGV)

#### Key Features

 * Zero configuration — install, activate, done
 * Click-to-load or scroll-triggered loading
 * YouTube thumbnail quality control (SD / HQ / Max)
 * 3 play button styles: YouTube-style, Circle, Minimal
 * Custom play button & overlay colours
 * GDPR / privacy notice overlay
 * Exclude specific pages by ID or videos by CSS class
 * No jQuery — pure ES6, < 2KB gzipped
 * Works with Gutenberg, Elementor, Divi, WPBakery
 * WCAG 2.1 keyboard-accessible placeholders
 * Caches Vimeo thumbnails via WordPress transients

### External services

This plugin can connect to external video services to display lazy-loaded video 
thumbnails and metadata.

#### YouTube

When YouTube lazy loading is enabled, the plugin uses YouTube’s public thumbnail
CDN to display thumbnail images for YouTube videos. The visitor’s browser requests
the thumbnail image from YouTube when a lazy-loaded YouTube placeholder is displayed.
The request includes the YouTube video ID in the thumbnail URL and may include normal
browser request data such as the visitor’s IP address and user agent.

This service is provided by YouTube LLC. Terms of Service: https://www.youtube.com/

#### Vimeo

When Vimeo lazy loading is enabled, the plugin optimizes page performance by replacing
heavy video players with a lightweight placeholder image. To generate this placeholder,
your WordPress server makes a secure background request to Vimeo’s public oEmbed
API to fetch the video’s thumbnail URL and, optionally, its title. To minimize external
requests and maximize site speed, this data is automatically cached locally using
WordPress transients, meaning the server only contacts Vimeo when the metadata isn’t
already saved.

During this brief server-to-server connection, your site shares minimal, standard
data with Vimeo to fulfill the request. This includes the specific Vimeo video URL(
which contains the video ID) and a standard User-Agent string identifying your website’s
URL alongside the plugin’s name and version. No personal user data is transmitted,
making it a seamless and privacy-conscious way to boost your site’s loading times.

## FAQ

### Will it work with my page builder?

Yes. The plugin uses PHP output buffering to intercept all video iframes and `<video
>` tags regardless of how they were added to the page.

### Does it support YouTube Shorts?

Yes, YouTube Shorts use the same embed format and are handled automatically.

### Will it break my video popups / lightboxes?

Add the class `no-lazy` (configurable under Settings  VidDefer Exclusions) to any
iframe, video element, or wrapping figure tag you want to skip.

### Does it require an API key?

No. YouTube thumbnails use the public `img.youtube.com` CDN. Vimeo thumbnails use
the public oEmbed endpoint.
