[iframe src=”http://www.youtube.com/embed/7_nAZQt9qu0″ width=”100%” height=”500″] shortcode 
should show something like this:
<iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/7_nAZQt9qu0?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe>
WordPress removes iframe html tags because of security reasons. 
Iframe shortcode is the replacement of the iframe html tag and accepts the same params as iframe html tag does. 
You may use iframe shortcode to embed content from YouTube, Vimeo, Google Maps or from any external page.
If you need to embed content from YouTube, Vimeo, SlideShare, SoundCloud, Twitter via direct link, you may use <code>[embed]http://www.youtube.com/watch?v=7_nAZQt9qu0[/embed]</code> shortcode. 
[embed] shortcode is a core WordPress feature and can <a href="https://codex.wordpress.org/Embeds" rel="nofollow ugc">embed content from many resources via direct link</a>.
Important: You can not embed HTTP pages into HTTPS pages and vice versa. 
So the protocol (http or httpS) for parent and embedded page should match.

This plugin improves page load time and increases your Google PageSpeed Score. It works with oEmbed and replaces embedded Youtube and Vimeo videos with a clickable preview image. 
By loading videos only when the user clicks on the preview image, no unnecessary JavaScript is loaded. Especially on sites with many embedded videos this will make your visitors happy. Additionally, all Youtube videos are loaded in a privacy-enhanced mode using the “https://www.youtube-nocookie.com” embed URL.
This plugin works for your existing YouTube and Vimeo blocks. No vendor lock-in and no custom shortcodes: Easily turn the plugin on and off anytime.

Lazy Load for Videos

We have pages with multiple videos and that slowed down the page load and increased network traffic. This plugin improved it a lot. Reduced blocking of some pages with seconds and reduced the page load from 3MB to 1,3MB.



Works great

Hi there,
your plugin ist really great! It kills several problems with one stone for me.
Very nice!
Keep up your good work and thanks very mutch for this plugin.

:-)

Very cool!


I noticed Squarespace has a much slicker way of loading and showing embedded videos, and I wanted it.   This plugin works perfectly to provide it so that my video portfolio page loads faster and looks better.  Thanks to the developer!


Simple solution for making video pages fast like Squarespace

Boost page speed by replacing embedded YouTube and Vimeo videos with a clickable preview image. Video scripts only load on click.
