Centering Background Video on mobile

Hi guys! Long-time Webflow user, first-time poster! Happy to be here!

I can’t, for the life of me, make the BG video center on mobile. Looks great on all other devices, but on mobile, it stays flush left. What can I do to fix this?

Here is my site Read-Only: Read Only Link

Thanks for your help in advanced guys!

Actually in your read only link I can’t see the bg video on mobile devices

That’s odd. It works once published. Now I’m really confused. What do you think is going on?
