interesting Question – and still relevant after such a long time.
I also wondered about the poorer loading times of a start page – especially these resources were named there for the poorer values (pagespeed insights – lighthouse). It should be possible, with the above-mentioned settings, not to load these resources if you have not selected videos as slides.

btw: I had a similar experience last week. Everything that was working fine was suddenly showing up as broken on the pages. What I had not considered was that I had changed my bank details in the meantime, but had not updated them on Google. Trivial – but with a big effect.

next: you can exclude some scripts (or css) from merging by:

function avia_exclude_files_from_compression($excluded_files){
  // exclude css 
  $exclude_css = array( 'layerslider', 'abc', 'xyz');  // comma separated list of enqueue names
  $excluded_files['css'] = array_merge($excluded_files['css'], $exclude_css);

  // exclude js files
  $exclude_js = array( 'avia_google_recaptcha_front_script', 'abc_script');   // comma separated list of enqueue names
  $excluded_files['js'] = array_merge($excluded_files['js'], $exclude_js);
  return $excluded_files;
}
add_filter('avf_exclude_assets', 'avia_exclude_files_from_compression', 10, 1);

f.e. in combination with my borlabs cookie plugin – i had to exclude the recaptcha script of google to work fine:
avia_google_recaptcha_front_script

Try to install that little plugin: https://wordpress.org/plugins/dark-mode-toggle/
Even in the free version there is an option to exclude Elements from dark-mode via class (dmt-filter-1)
so if you insert on child-theme functions.php:

function exclude_from_darkmode(){
?>
<script>
window.addEventListener("DOMContentLoaded", function () { 
(function($) {     
  $('.logo, #footer, #socket').addClass('dmt-filter-1'); 
})(jQuery);
});
</script>
<?php
}
add_action('wp_footer', 'exclude_from_darkmode');

these elements and all child elements were excluded. The same if you insert to alb element that custom class!

by the way : you can exclude a whole color-section but include again a child by adding the same class to it :lol : -1 x -1 = 1
I don’t know why images on sliders (see example page) are excluded from the outset.

or use the grid-row :

very comfortable even in responsive case – you can decide to have the text for the left cell on top and for the right cell vice versa etc. pp.
To create a non-fullwidth element for the grid-row could be reached easy.

one thing to mention – that video is from 2018. Meanwhile, many deprecated functions have been removed in newer versions of jQuery.

so the video shows:
$(window).load(function(){ …
this is now:
$(window).on('load', function(){

instead of using that script Mike linked to – use the filter:

add_filter( 'avf_default_lightbox_no_scroll', '__return_true' );

So you have set the image to float left f.e.

And there is only one line of text next to it! – asign a custom class to that text-block to better select it specifically
then try

.avia_textblock.alignmiddle > p {
  display: flex !important;
  align-items: center;
}

see here with an alternative Layout to reach what you like to have:https://webers-testseite.de/steveorrmedia/

but this will only work if there is only one p tag inside that text-block element. Otherwise you had to use the text-mode of the text-block to set the image in one div – and the text besides in another div. By this we can use then the flex method again with these two containers.

And you do not like to use this layout?

bei Enfold 5.6.6 ist die Option direkt unterhalb des Logos zu sehen: : Theme Optionen – Transparency Logo Options –
wähl das mal aus, dann gib das Logo an, welches du im Transparenz Modus nutzen möchtest.
Das andere Logo ist für die nicht Transparenzen zuständig.

Bessere Ratschläge könnte ich nur geben, wenn ich die Seite sehen könnte.

but please if it is possible this should be default setting !!!
And perhaps only a checkmark if you realy need that.

But if i inspect the DOM before that change – f.e. on autoplay even there – no parameters were set at the url
just that f.e. src="https://www.youtube.com/embed/G0k3kHtyoqc?feature=oembed"

no autoplay=1 is set to the url etc. – with the changes above – no rel=0

PS: on sliders there are those $video_data’s going to the output of the video url:

ok i see:
the lightbox script got his titles from the img tag not the anchor !
so on line 784 (enfold 5.6.6) and on line 806:

Guess title should be:
title="{$lightbox_title}"
i do not know how to handle the $prev_img_tag if we had to change that too.

on default there should be a working choice for that under the option to choose the lightbox option:

but i recognized now that for galleries – that option has no influence – but test yourself on your gallery. On Masonry Gallery it works well to choose “no text”

if so we had to inform a Dev here on board – to fix it.

in the meantime you can set the mfp-title to display: none

div .mfp-title {
  display: none !important;
}

i don’t know how your plugin react on this. My solution above is only for working with snippets inside your child-theme functions.php.

i do not know how those regenerate Plugins do their job. – F.e. if they remove allready existing recalculated images.
There is one Plugin from : Shortpixel Group: https://wordpress.org/plugins/regenerate-thumbnails-advanced/

if this plugin recalculates the images – you can have under advanced options to erase non recalculated images from the uploaded folder.
(click to enlarge:)

btw.: this plugin also can create new image sizes.The only thing I notice is that the compression level does not work for Enfold formats.
But you can set that beforehand by f.e:

add_filter("avf_jpeg_quality", "avf_set_quality_mod", 9999, 1);
add_filter("avf_wp_editor_set_quality", "avf_set_quality_mod", 9999, 1);
function avf_set_quality_mod($quality) { $quality = 55; return $quality;}

Yes – thats only a matter of youtube (Google) settings. In the past, it was possible to prevent various things by adding an attachment to the video url. They have decided not to allow this any more.

z.B.: https://www.youtube.com/embed/1YQ8iP0DiUk?autoplay=1

So the Google people decided to patronise their users even more. i didn’t find anything on https://developers.google.com/youtube/iframe_api_reference.

I really do wish that I was wrong about all this.

Try this and for changing the direct next post:

https://kriesi.at/support/topic/enfold-image-sizes-3/#post-1109028

But : after erasing some of those image-sizes – you had to regenerate your thumbnails : there are some good plugins to do so.
f.e.: https://wordpress.org/plugins/force-regenerate-thumbnails/

// Disable loads of Enfold & WP image sizes upon upload
// do image sizes manually, double-size with high compression for retina screens
// use Photoshop to set exact double size and quality between Q30 and Q40
add_action('init', 'remove_enfold_image_sizes');
function remove_enfold_image_sizes() {
// do NOT remove widget size, is used in backend portfolio items!
// remove_image_size('widget');
  remove_image_size('square');
  remove_image_size('featured');
  remove_image_size('featured_large');
  remove_image_size('portfolio');
  remove_image_size('portfolio_small');
  remove_image_size('gallery');
  remove_image_size('magazine');
  remove_image_size('masonry');
  remove_image_size('entry_without_sidebar');
  remove_image_size('entry_with_sidebar');
  remove_image_size('shop_thumbnail');
  remove_image_size('shop_catalog');
  remove_image_size('shop_single'); 
    remove_image_size('shop_gallery_thumbnail');
}
// Remove unneeded WP image sizes
add_filter( 'intermediate_image_sizes_advanced', 'prefix_remove_default_images' );
// Remove default image sizes here. 
function prefix_remove_default_images( $sizes ) {
// do NOT remove small and medium sizes, they are used in backend Media Library!
// unset( $sizes['small']); // 150px
// unset( $sizes['medium']); // 300px
 unset( $sizes['large']); // 1024px
 unset( $sizes['medium_large']); // 768px
 return $sizes;
}
