HELP! Banner video loads and causes index page to "jump" to bottom.

Site URL: https://centerpointfl.org

My site has an Index page as the home page. The main index page has a video in the banner. When the site loads, it opens with the fallback image, then the video begins to play and the entire page JUMPS down 2 pages in the index. When I use a static image in the banner, I don't have this behavior--only with the video. Any ideas? 

I have nothing in the page header code injection box. Running Bryant template. Version 7.0.
