Embed video pop up for product

Hi I have installed it on this page http://www.bowensuppliesbyhelen.com/product/applicator-wrap-knee-elbow/ On page load you can see the thumbnail but disappears when page loaded. I want to click the image then it opens lightbox with video like your demo site. Any ideas whats going on please?

This is the plugin that im using now WooCommerce Video Links - Product Embedded Videos.

I have tried the following and none of them work too.
https://wordpress.org/plugins/woocommerce-html5-video/
https://wordpress.org/plugins/woocommerce-video-product-tab/
https://wordpress.org/plugins/yith-woocommerce-featured-video/

Any ideas will be gratefully appreciated.

Thanks
Robert
