I have asked there! Thanks for checking it out!
I should also add that we have found this only seems to happen in safari, in chrome its centered and this happens regardless of which full screen background videos are added as the header!
they have a support forum on WP, which I have also posted in, but if it is a theme issue, why does it happen in other themes? My best guess is that it has something to do with the “responsive” module that resizes things.
