Hi,
Each Youtube video generates different versions for thumbnail: standard, medium, high quality and maximum quality of resolution. It seems that the video you're using doesn't have maximum version which is rendered by default in this video module.
You will need to customize a little bit here by opening this file: /templates/ja_healthcare/acm/video/tmpl/style-1.php
At approx line 55, you see this line of code:
<img alt="" src="http://img.youtube.com/vi/<?php echo $video_link; ?>/maxresdefault.jpg" />
change it to:
case 'youtube':
?>
<img alt="" src="https://img.youtube.com/vi/<?php echo $video_link; ?>/hqdefault.jpg" />
The thumbnail will show up then.
FYI: if you want to use other versions of thumbnail, this is a good tip
Regards
