How to Embed Audio & Video with Layers
Embedded content is supported by the WordPress core and enhanced in Layers through a Rich Media meta field on your post editor that allows you to attach an oEmbed URL to your post in place of a Featured Image. This is useful if you have audio or video content you want displayed in the Layers Post Widget on builder layouts that is also displayed in archives and single posts.
Embeds As Featured Images
The “Video URL” field can actually take any oembed URL including vimeo, YouTube, SoundCloud and Twitter.
Embeds in Posts
To embed oEmbed content in a post, simply drop the oEmbed URL into your content where you want the player to appear and WordPress will do the rest. Be sure to save the post with the Visual tab selected.

Embeds in Widgets
You can add embeds to the Slider and Content widget under the Featured Image option in the toolbar. Simply add the oEmbed URL instead of an image and set the ratio to rectangle.
