Place video behind both header and section?

Is it possible to place a video as a bottom layer, under both the header and the following section under?

So having the video covering the whole yellow area shown here, but laying under all text and logo/menu:

Why you don't use Video Background?

@tuanphan aah of course, thanks. But it doesn't go behind the footer?

And is it possible to set the video to blend mode multiply by the way?

#1. To make it behind footer you will need to use code. You can add first then share url, we can check & give the code

#2. I don't know this.
