How do I get rid of white space when I add a video "section"?

Even when I try fill screen it leaves a big amount of white on top and bottom of the video. I am trying to make the three minute video fit the screen and leave no white below it. Is this possible without having to shorten my video to 1 minute? thanks. wesbite page is attached https://www.omegachurchsa.org/home-testing
