Video section too large on desktop

[DASCPA]

Hello, Looking to reduce the size of the video section in dawn on desktop. Scale is perfect on mobile but too big on desktop. See screenshot here. Plus see a video section screenshot on 'label source' of how it should look. Thanks

Note: your code is too messy, I tried my best to reslove this problem.. If it will not work dm me for further detalis 
1. Go to Online Store -> Theme -> Edit code.
2. Open your theme.liquid file
3. In theme.liquid, paste the below code before </head>

@media (min-width: 1024px) {
    #Deferred-Poster-Modal-40367269478711 {
        width: 800px !important; 
        height: 450px !important;
        display: flex !important;
        justify-content: center !important;
        align-items: center !important;
        margin: 0 auto !important; 
        overflow: hidden !important; 
    }

    #Deferred-Poster-Modal-40367269478711 img {
        width: 100% !important;
        height: 100% !important;
        object-fit: cover !important; 
        display: block !important;
