I'm trying this, which seems to work successfully...
$(window).load(function() {
$('#overlay-preload').fadeOut('fast', function() {
$('.each-blog-video-container').each(function() {
var videoData = $(this).find('span').attr('data-video');
$('.each-blog-video-container').append(videoData);
});
});
});
<div class="each-blog-video-container">
<span data-video='<iframe src="//player.vimeo.com/video/<?php the_field('video'); ?>?title=0&byline=0&portrait=0&color=ffff00" width="540" height="304" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>'></span>
</div>
