I need to make a full screen video opening for my website

Hi there,

I would like my website to open with a short video every time someone open the homepage. The video currently appears as a separate window after a few seconds that needs to be played and closed manually to navigate the website. I would like that video to be full-screen, starting and disappearing by itself. If it require to buy a plugin to make it work I'm happy to do it.
