<a class="btn modal-trigger" href="#<%= episode.name %>"><%= episode.name %></a>

<source id="<%= episode.name %>" src="<%= episode.url %>" type="video/mp4; codecs='avc1.42E01E, mp4a.40.2'">
Your browser does not support the video tag.
</video>
</div>
</div>
<% end %>

Answer 1

First of all, you are setting the same id for multiple tags (div, video, source). ID must be unique in entire document.
Considering that you want to stop video when modal close, you can use the callback for complete event (modal close), in your Javascript/jQuery code:
$(document).ready(function(){
var videos = $("video");
$('.modal-trigger').leanModal({
complete: function() {
videos.each(function(){
this.pause();
});
}
});
});
This will pause all videos when modal close.

I know this is an old question, but it came up for me in search. I solved it by adding video into modal when it opens, then removing it when it closes. Here's my work.
$(document).on('click','.video-butt',function(){
$('#video-modal .video-container').html('<iframe id="myIframe" width="300" height="200" src="' + $(this).attr('href') + '?rel=0" allowfullscreen="true" ></iframe>'); // embed video
$('#video-modal').modal('open');
return false;
})
function videoTrash(){ //remove video embed on close
$('#video-modal .video-container').empty();
}
$('#video-modal').modal({onCloseEnd:videoTrash}); // initialize materialize modal
html
<div id="video-modal" class="modal black">
<div class="modal-content white-text">
<div class="video-container"></div>
</div>
</div>
the trigger link
<a class="btn btn-flat video-butt" href="https://www.youtube.com/embed/hO4tW8Py2xc">watch the video</a>
