Brooklyn Theme issues with mobile device and background videos


I am about to pull the trigger on buying the Brooklyn theme. I have been testing the demo pages on my computer / ipad and phone to see what works and what doesnt.

I only seen one instance where the video in the header was working across all 3 devices. Every other example of a video background anywhere in the theme does not work in either the ipad or android phone. Is it possible to have a video background that works everywhere…or better yet parallax video?

Is there a theme that you recommend that can do this. I require it as it is for a drone cinematography company that also does surveying so the video is ideal.

Thank you in advance for taking the time to read this and to reply back.
