Hello, I was able to install the one page theme - Please disregard the title (or change it) I need to figure out how to add a video background to the top of the page. Thank you! 

I've followed these instructions but I must still be doing something wrong:

ref: http://codex-themes.com/scalia/pages/video-backgrounds/video-background-areas/

I have attached a screenshot of my Fullwidth settings.

Sorry I keep editing my post - I am making progress:
I found a page that was similar and can now get the video to appear- but I would like it to take up the full width of the page (and maintain the height, even if it cuts off) http://seanpatrickspetspa.com/accelerator-photo-3/

After working on this all day - I can get it to display in WPBakery, but not on the actual page. Tested with all three browsers. 

Ok - So I solved my own problem, finally. LOL I apologize for all of the posts!! You can remove this one, but if you want to keep it for other users: I disabled all of my plug-ins and slowly re-enabled them one by one. This pointed to a conflicting plug-in that loads Facebook images dynamically on the home page: "Facebook Photo Fetcher."

Good luck all, and thank you for the great theme! Looking good now.
