Problem:

The issue here is that the user's custom video fields are not displaying on the frontend with the embedded video player, rather they are just displaying the URL.

Solution:

In this Users case I saw that their video format was .MOV which is not one of the formats that the wordpress embedded player supports.

To get a list of the supported video formats you can see the link below.
