Thanks for the response. Yes, the theme has been set and configured, though I do see a notification to set up the theme when I log in. I just re-ran the configuration process and tried setting the video background again, but to no avail.

The site is hosted on wpengine, and the theme is being used to re-design the website in the wpengine’s staging environment. As the website is my clients’, I am afraid I cannot give you access to the admin as such. Can you please give me a probable list of steps that I need to follow, or check to see what’s wrong?

Parallel pro does support video background, right?
