Background Video control

Hi there, dear HB-themes. Thank you for great theme, called Highend.
First of all: sorry for my bad english.

I want to make one-page scrolling presentation, with background videos on each slide.
Is there a way to control background videos? like play/pause buttons?

First video is loop-playing, and next video won’t start.

If i try to use big videos in visual composer, instead of background videos, how i can use slide-navigation between them? like in scrolling-presentation demo?

Please help =)
