Hi,

Hope you guys are safe.

I have a background video that plays on loop when on the home page, however, as it's a youtube video it doesn't function perfectly as I want it to, intermitently it will show the youtube banner and logo and sometimes even stop working propperly. I was wondering if you had a solution for this. Is there a way I could just make a video file play rather than having to use youtube as an extention.
