HTML embed video is stuck at fullscreen

Hi

I’m having issues with a embedding a video onto my page.
No matter what I try it’s stuck in fullscreen mode.
I purchased an addon hoping it would make life easier but I’m still getting the same problem.

Thanks in advance

So I think my issue was the fact I had CSS changing my background video.

Now that I have resolved that issue, my new html5 embed video doesnt show at all.

I will share screenshots of my background CSS & my new video embed settings -
