I found the section and code. I just need some knowledge to change it. 
The video is far to big. As seen at the bottom of my page, (the vertical video) https://rmtperformance.com/pages/our-team-cars

Hello @Reinhart ,

To adjust the video size, You need to add this code 

Go to Shopify admin >  Themes  > Edit Code > Search Base.css file and put the given code at the bottom of base.css file

This Code for adjust the video size

.media > *:not(.zoom):not(.deferred-media__poster-button), .media model-viewer {
     
    height: 400px; /* adjust the height according to your requirement */
    width: 100%;
}

Now Add this code for adjust the Player Button

.deferred-media__poster-button{
top: 12%;
}

Thank-you for your efforts, this did not work unfortuantley. 

This page is a page created in Shopify. And the video was added using a normal video element if that helps at all.
