Better Core Video Embeds


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.


  • Example of an embedded Youtube video in a post when using Better Core Embeds


  1. Log into WordPress
  2. Go to Plugins, Add New
  3. Search for Better Core Video Embeds
  4. Click Install Now, then Activate
  5. Embed a Youtube and Vimeo videos into your posts as you would normally using an embed block, or just pasting the video URL into the editor.


What does the plugin actually do?

It filters the embed block output to prevent Youtube and Vimeo scripts be loaded on the page until a users clicks to watch a video. It does this my replacing the normal embed markup with a video thumbnail image. When the user clicks on the image, the embedded video is called.

What happens to my videos if I stop using this plugin?

The plugin provides progressive enhancement, therefore if you no longer use this plugin, your embedded videos will revert back to the default WordPress behaviour.

Can I set a custom thumbnail, rather than the embed thumbnail?

Yes! As of version 1.3, you can set a custom thumbnail on the embed block and this will be used as the video thumbnail or poster image on the front end of the site.


It does exactly what it needs to out of the box, and support has been very prompt.
This is a brilliant plugin that does what it does perfectly with no fuss or muss. If you embed any videos on your site, this is a must.
I’ve used this since I first became aware of it and it does everything it should really well. Support is prompt also. Very happy.
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”:
