This plugin provides page optimisations for pages and posts which have embedded Youtube, Vimeo or Daily Motion videos which have been added using the core embed block.
Without this plugin, when using the core embed block, when your page loads, lots of external scripts and styles are loaded from the embed service, regardless of whether a visitor actually interacts with the embedded video.
This plugin prevents these scripts and styles from loading until the user actually interacts with the video. It does this by replacing the video embed, on page load with the video thumbnail image (added on Youtube, Vimeo or Daily Motion). When a user clicks the thumbnail the embedded video, along with associated scripts and styles are loaded.

Better Core Video Embeds


This is an example of an excellent plugin. Just activate and get immediate enhancement when using the embed blocks from WordPress. If deactivated, everything still works as before, but then without the enhancement. No "lock in":


Does what it says without any fuzz. Very good!

A plugin which enhances the core embed block for Youtube, Daily Motion and Vimeo videos by not loading unnecessary scripts until they are needed.

ATTENTION for WP Version 5+: This plugin does not work with Gutenberg (no problems with Classic Editor plugin though)! Gutenberg brings its own HTML structure for oEmbed elements, which is quite difficult to target.
This plugin checks, if the first line of the content is a valid oEmbed URL. If that is the case, it replaces the thumbnail image with the oEmbed element (e. g. with a YouTube video). Now you don’t have to care too much about a thumbnail image, since instead you would see the video or any other oEmbed content. You can even e. g. watch videos on your blogs front page without opening the post.
Works for all WordPress contents, which have a thumbnail set and are not password protected.
The active WordPress Theme must use the_post_thumbnail() or get_the_post_thumbnail() functions for this to work!

Replace Thumbnail with oEmbed

Replaces the thumbnail image with the oEmbed element from the first line of the content.
