Video is played differently

[Tower92]

Hey,
I have integrated a video into my website via html. With the help of Javascript, the video appears from a certain height and disappears again after a certain height. If I access the website via www.noals.de, everything works as it should. But when I go to Contacts, for example, and then back to the Home page via the Site title, the video is permanently there.
What could be the reason for this?

My Website

My code:

Custom CSS for Desktop Version

#fixed-video {
    position: fixed;
    top: 55%;
    left: 62%;
    transform: translate(-50%, -50%);
}

Custom <head> content

<script>
jQuery(document).ready(function($) {
    var $window = $(window),
        $fixedVideo = $('#fixed-video'),
        videoHeight = $fixedVideo.outerHeight(),
        showAtHeight = 500,
        hideAtHeight = 1850;

    $fixedVideo.hide();

    $window.scroll(function() {
        var scrollTop = $window.scrollTop();

        if (scrollTop > showAtHeight && scrollTop < hideAtHeight) {
            $fixedVideo.fadeIn();
        } else {
            $fixedVideo.fadeOut();
        }
    });
});

 </script>

Thanks in advance!

<script>
var $fixedVideo;
var showAtHeight = 500;
var hideAtHeight = 1850;
var videoHeight;

jQuery(document).ready(function($) {
    $fixedVideo = jQuery('#fixed-video')
    videoHeight = $fixedVideo.outerHeight();
});

jQuery(window).on('scroll', (function() {
    var scrollTop = window.scrollY;

    if (scrollTop > showAtHeight && scrollTop < hideAtHeight) {
        $fixedVideo.fadeIn();
    } else {
        $fixedVideo.fadeOut();
    }
});

jQuery(window).on('resize', function(){
    videoHeight = $fixedVideo.outerHeight();
});

window.laytheme.on('newpageshown', function(){
    $fixedVideo.hide();
});
</script>

the reason it didnt work, jQuery(document).ready(function($) { is only triggered once!

@arminunruh Thanks for your reply and sorry for my late reply.

I implemented the code you provided. The video is displayed the whole time. I think I understood the content within the link you provided but I cannot figure out a solution.
