well – put your code block just inside a color-section – that color section set custom class to: special-vids
inside you got your html structure like:

<section id="scrubs" class="vid">
	<div class="holder">
		<video src="/wp-content/uploads/Time-Lapse.mp4" autoplay muted loop playsinline></video>
	</div>

	<div class="story">
		<div>
			<h3>In the heart of Wildrise…</h3>
		</div>
		<div>
			<h3>…where the breezes play.</h3>
		</div>
		<div>
			<h3>We embrace the call of the wild each day.</h3>
		</div>
		<div>
			<h3>Untamed places stretch,</h3>
		</div>
		<div>
			<h3>vast and wide.</h3>
		</div>
		<div>
			<h3>Whispering secrets of a world outside.</h3>
		</div>
	</div>
</section>

put this to your child-theme functions.php:

function scrub_preparation_of_color_section() { 
?>
<script>
window.addEventListener("DOMContentLoaded", function () { 
	(function($){
		$('.avia-section.special-vids ').each(function() {
			var vids = $(this).find('.vid').detach().html();
			$(vids).prependTo($(this));
			$(this).addClass('vid').find('.container').remove();
		});
	})(jQuery);
});
</script>
<?php
}
add_action('wp_footer', 'scrub_preparation_of_color_section');

see: https://webers-testseite.de/scrubbing-videos/

my css on that page is:

.responsive body#top {
    overflow-x: visible;
}

#wrap_all {
    overflow: visible;
}

.avia-section.vid {
  height: 600vh;
  position: relative;
}

.avia-section.vid div.holder {
  position: sticky;
  top: var(--enfold-header-height);
}

.avia-section.vid video {
  width: 100%;
  height: 100vh;
  object-fit: cover !important;
}

.avia-section.vid div.story {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
}

.avia-section.vid div.story div {
  height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
  text-align: center;
}

but i do not want to style it till the end. have a look how that is made in that video. – and how to handle the other .avia-section
Edit: you had to adopt now the scrubbing script to its selectors. And perhaps a debounce and resize will be needed.

you can use the embedded debounce function of enfold:

function ava_add_custom_script(){
?>
<script>
(function($){
  function b() {
      // here comes the script …
  }

  $(window).on('debouncedresize', function() {
    b();
  });
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'ava_add_custom_script');

Hello
Since the Enfold update 6.0.8 the left menu appears in English, it should be in German. There seems to be something wrong with the language in the 6.0.8 update. I manage numerous Enfold websites.
Please check this.
Many thanks, Simon

i guess you have that warning on uploading your icons to fontello about compound path.
you can edit your vector based icon f.e. in illustrator – open your svg and look at Object Menu – Compound Path – create
i hope that this will be the names – because i’m working on german versions : Objekt – zusammengesetzter Pfad – erstellen.

Working with Pathfinder is not enough. You had to go that way.

________

Mikes Way is to substitute an existing entypo-fontello icon by an image. Big advantage – you can use the icon font to insert even colored svg icons.
see here: https://enfold.webers-webdesign.de/colorized-font-icons/

Well enfold provided the option to only show submenu items on hover or on click.

If you choose click we can edit that to only show one toggle open.
then put this to your child-theme functions.php:

function only_one_submenu_open_on_burger(){
?>
<script>
window.addEventListener("DOMContentLoaded", function () { 
  (function($) {
    $('body').on( 'click touch', '.av-active-burger-items > a', function () {
      $(this).parent('li').siblings().removeClass('av-show-submenu');
      $(this).parent('li').siblings().find('ul').slideUp( "fast");
    });
    $('body').on( 'click touch', '.av-active-burger-items .av-width-submenu > a', function () {
      $(this).closest('.sub-menu').siblings().find('li').removeClass('av-show-submenu');
      $(this).closest('.sub-menu').siblings().find('ul').slideUp( "fast");
    });
  })(jQuery);
});
</script>
<?php
}
add_action('wp_footer', 'only_one_submenu_open_on_burger');

after doing that i will have a look to your site to optimize if needed.
