Scrolling text long delay before start after video html and css

Question

I have just finished working on a new website for my festivals business and the scrolling text "ticker tape" is taking an age (Sometimes up to a minute) to load especially on phones. It's just on our camping page though (https://wildfestivals.co.uk/school_holiday_camping.html), all other tickers and videos are working well together. My question is, is it the video that's delaying the start and is there a way I can keep both items on there, but speed the start of the ticker up at all?

I'd hate to lose the function. Does anyone know a way that I can sort this please? As you can see I am a have a go guy, not a pro developer.

@-webkit-keyframes ticker {
  0% {
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
    visibility: visible;
  }
  100% {
    -webkit-transform: translate3d(-100%, 0, 0);
    transform: translate3d(-100%, 0, 0);
  }
}
@keyframes ticker {
  0% {
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
    visibility: visible;
  }
  100% {
    -webkit-transform: translate3d(-100%, 0, 0);
    transform: translate3d(-100%, 0, 0);
  }
}

.ticker2-wrap {
  position: static;
  left: 0;
  width: 100%;
  overflow: hidden;
  height: 2rem;
  background: rgba(0, 0, 0, 0.2);
  box-sizing: content-box;

.ticker2-wrap .ticker2 {
