@ben I've fixed the video size from the CSS section. I think we have a bug right now and the width slider is not working properly.
Below is the CSS I've used. If you need other sizes, just change the width and height in pixels as needed.
#overlay wdg-other-splash .media iframe{
height: 500px;
width: 500px;
}
#overlay.mobile wdg-other-splash .media iframe{
height: 360px;
width: 360px;
}
