Transparent videos on mobile issue

Hi

I have created 2 file versions of a video I converted in Rotato, one for chrome one for safari.
Both work on PC & mac but the image doesnt appear on mobile.

Could somebody take a look at my read only site and see what I’m doing wrong?

The video I’m talking about is the HTML Embed 3.

Thanks in advance.


Here is my site Read-Only:
