Q:

Center video zoom

I have a video which is set on full window height with this css style 
width: auto;
height: 100vh;
min-height: 100%;
position: absolute;
background-attachment: fixed;
left: 0px;
object-fit: fill;
z-index: -1;
overflow: hidden;

but the problem is, that when i open it on mobile, the video is zoomed to left bottom corner.  Is there any way how to zoom to center? 

A:

use
left: 50%;
transform: translateX(-50%);
