First video widget as Background and last widgets above the video Widget.
This tutorial provides the steps to add a video background section using the first video widget as background and last widget over the background widget inspired by First image widget as Background and other left widgets above the image Widget in Genesis.
This tutorial is good for after header location. I recommend you to follow other video background tutorial if you are not familiar with CSS. Video backgrounds are difficult to customize and so it is recommended to use other video background tutorial where the video outputs are great.

Even video shortcode doesn't include muted filter and so we have to add an additional filter to add them.
Add the following in functions.php
