Landing page video thumbnail not autopopulating

[cierac]

Why is the video thumbnail at the bottom of this page not autopopulating? The thumbnail only shows when they click play, which isn't usually the case.cWe have a image thumbnail link in the marketo landing page variables and the embed link. 
Here is the preview link. https://it.recastsoftware.com/lpeditor/devicePreview?p=3497&t=q5c3my3oev7iinfIkIxhCw,,&m=563-ODB-688

@cierac , I don't think your preview link is working

Cheers
