This was exactly was I was looking for, great answer, but for any PHP newbies, who will likely use it with opening and closing tags I added a “revised” Version, I myself hat trouble with the code because I forgot the “:”.
Anyways perfect Code for the Problem, using Repeater is not an alternative for blocks.
<?php $field = get_field('video_feature');
if ($field && $field['video_description'] && $field['video_description']): ?>
