Hello Richard,

Without modifying the template, disable hero section entirely for the page, do not set any header image for the page and then add a cover video block:

Hmm, ok try adding avideo embed wpbakery element with class 'full' added to additional class name(s), it will stretch the block full width.

Yes, the problem is that we don't have a header video background section in California similar to  header background image.

I am not aware of any other option but here are the styles for the background image header

https://prnt.sc/gYfORnOGLmbM

.project-bg-image {

    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-size: cover;
    background-position: center center;
    background-repeat: no-repeat;
}

that can be applied eventually to a video header

the fonts and styles for the captions are actually tied to the .project-bg-image CSS class

Hello Richard,

yes, custom CSS:

.clapat-counter .number {
     color: #000;
}

.clapat-counter .subject {
    color: #999;

}

change the hex color code and add the code to customizer -> additional CSS
