Hello,
Thanks for your Patience!
We have tried testing this and the conclusion we have come to, after testing this with different combinations for a while is that, the Aspect Ratio of your Video and the way you want to display your Video (as this is an Informational Video) is not best recommended to be used as a Youtube BG. The Usage Case of your Video will be best suited as an Embedded Video. The Function of the Youtube BG element is make the Video Fill the Container, adjusting the positions which does not make it an ideal choice for your Video. And it is also not responsive as you will need to set a fixed height for the Video to display properly. We have 1920x1080 Screen and the Code that works best for us is:

Hope this makes things clearer. So, it is much recommended to use your Youtube Video as an Embedded Video.
