Hi Brady-
There are two ways you can eliminate that border. First, if you edit your page and switch over to the Text editor, remove the class “bg-video-2” from the div surrounding your video embed. Right now, that line looks like this:
<div class="bg-video bg-video-2 color3-border-color" data-imhwpb-draggable="true">
Removing that class will eliminate the border. Otherwise, you can add this line of Custom CSS in your Customize > Advanced > Custom JS & CSS menu:
.bg-video.bg-video-2 iframe {
border: none;
}
