How to fix video slowing down page load time on WordPress

I have added a video to the homepage of my WordPress site. The site is loading slowly due to the video. I want to visit the site, first all the content of the homepage will be loaded, then the video will be loaded. For this, I've found this jquery script on a blog, but it is not working.

<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript">
 $(window).bind("load", function() {  

I have given the ID of 'movie-area' the section that contains the video. I am using CUSTOM JS & CSS plugin to write the code. The question is how do I trigger the video to make this function work properly. Should I put the name of the video on 'movie.html'?
