Emerge theme: video with text/transparent and sticky header

[Klaw2OC]

Hello everyone!

I am having two issues. 

1. I want my video section to look like the screenshot below: the video is on the right, while the text (and button) is on the left, and vice versa.

2. I'm trying to make the header transparent and sticky.

Any help is greatly appreciated.
