How to get the text and button to overlap the video?

[Nedsko]

Please have a look at the video I've attached below.

Now what I want is the text "Experience full auto like never before" and the learn more button to over lay the video, how do I do this? 

Just to let you know Ive used a custom code in the "custom liquid" section in dawn theme to make the video possible. I'm open to new ideas of how to add the same video on my website.

Thank you!
