Video background not showing

Hello, I’ve purchaded a new template (Frenzy) and when I tried to mod it by putting a background video, the video is now showing in the section where i want it. It’s like its behind something. I’m a noobie so probably some setting I’m getting wrong. Its supposed to be in the top section, which is completely green now. The green comes from the background color of the page wrapper.
