Video Overlay

Hi there, I am trying to add an overlay to the video. I have checked the box and added the colour/opacity but nothing is working?

The site is currently in a stage environment so I cannot provide a link. I have added the following custom CSS and it worked a treat but it isn’t very efficient as I’d much rather make the changes through Site Origin.

.vidbg-overlay {
background: #0000008a;
}

The pushlabs style sheet currently looks like this for the overlay style:

.vidbg-overlay {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
opacity: 1;
transition: opacity 0.5s ease;
}
