Video on mobile version of my page looks cut off/too short

Site URL: http://vessel.media

The video here looks to short so when a user visits the mobile site it doesn't just show video...it shows part of the other section as well...how to make this the whole mobile screen so they need to scroll down to see the next section and it looks clean?

Try adding to Design > Custom CSS

 /* mobile homepage top video */
@media screen and (max-width:767px) {
[data-section-id="620be0f660674727dd887368"] video {
    left: 0 !important;
    width: 100% !important;
    height: auto !important;
}
[data-section-id="620be0f660674727dd887368"] {
    min-height: unset !important;
    height: 25vh;
}}
