Could you update the URL of your site here so we can have a look?

As I can see that the video still looks fine on your site, in which screen / device you see the issue?

It looks like the header cover the video a bit

You can try opening the file: ROOT/templates/uber/css/custom.css and add this rule:

@media (max-width: 667px) {
  .home-demo .sections-wrap .section .section-inner {
    padding-top: 52px !important;
  }
}
