Front Page Video Section

Hi,

This is quite urgent. Please could someone help.
The video on the front page section will not work but yet when an email is entered in the subscribe to newsletter right at the bottom of the page the video will start working which is quite weird.

I need the video working constantly as it was. For some reason when the site was made live from a local host the video just stopped working and only shows a still image.

Is there a solution for this?
I tried deleting and installing the theme again but this did not work.

TIA
