Colour Section Background Video keeps looping.

Hey Corina,
Thanks for the link to your site, my research finds that this is a known, and argued expected behavior for the Vimeo player when a video is a background video.
I tested your video in a color section background & in a video element and found this a reasonable explanation and do not believe that it is a result of the Enfold element.
I did come up with a possible solution that works on my test site and also seems to work on your site.
The following script rewrites the iframe url after the video starts and breaks the loop, thus ending with the video on the first frame.
If you would to try this, add this code to the end of your functions.php file in Appearance ▸ Editor:

function custom_script() { ?>
    <script>
(function($){
      setTimeout(function(){
      $("#top.home #av_section_1 iframe").attr("src", "//player.vimeo.com/video/650191459?portrait=0&byline=0&title=0&badge=0&loop=0&autopause=0&api=1&rel=0&player_id=player_5394_254066182_1922605071&color=ef5e95");
      },800);
})(jQuery);
</script>
    <?php
}
add_action('wp_footer', 'custom_script');

The only other solution I can recommend would be to embed your video in a code block so that it is not a background video.

Best regards,

Hi,
I believe when the first loop of the video ends the still frame is the first frame of the video, check the direct link below, it doesn’t autoplay so you can see the first frame.
So to correct you should edit the video so the first frame is correct.

Best regards,
Mike
