Answer 1

这是您想要的效果吗？

#home-bg-video {
    position: fixed;
    top: 0;
    left: 0;
    min-width: 100%;
    min-height: 100%;
    width: auto;
    height: auto;
    z-index: -1;
    background: #000000;
    background-size: cover;
    animation: mymove 2s;
    -webkit-animation: mymove 2s;
}



/* Safari 4.0 - 8.0 */
@-webkit-keyframes mymove {
  from {
     -webkit-transform: translateX(50%) translateY(50%);
    transform: translateX(50%) translateY(50%);
  }
  to {
     -webkit-transform: translateX(0%) translateY(0%);
    transform: translateX(0%) translateY(0%);
  }
}

/* Standard syntax */
@keyframes mymove {
   from {
     -webkit-transform: translateX(50%) translateY(50%);
    transform: translateX(50%) translateY(50%);
  }
  to {
     -webkit-transform: translateX(0%) translateY(0%);
    transform: translateX(0%) translateY(0%);
  }
}
