Plugin for background video inhomage with header and subheader in background

Before anything, I have to commend everyone for their gracious help and support. You guys are so unselfishly helpful and supportive. Can’t say enough.

With that being said:

I have a website where I would like to display a fullwidth video, that has a button that says “PLAY” and the video would display. But I still want to be able to have a Header and a subheader and under it a button that says “play video” and then “learn more”

OR

A way to have a background video that whenever you click the play button, the header and the subheader dissapears and all you see is the video and once the video is done, the header and subheader reappears.

I know this is a lot, and I hope that made sense, but is there a way I can do this, through either a plugin or some other way.

I have access to all genesis themes and DIVI themes.

Just incase some of you guys may know a way to get this done.

Your help would greatly be appreciated, I know I’ve asked questions in the past and I wish I can lend more support , but I’m not too knowledgeable so I feel bad at times for asking questions ??
