Background video freezes in Chrome

Hi I’m trying to use background video on a project. For some reason when I load the page, - its the “About” page… The video shows as still frame. But when I click on the area that shows responsive layouts up top it starts playing.

I’ve seen a few threads where ppl have had to add custom code in the head area to get things working, and some threads that say this was resolved…

Any help would be much appreciated… Link is here, its the about page:

Thanks!
