html

<div id="overlay"></div>  <div class="col-md-6">     <div id="introright">         <video poster="img/whoweare.jpg" preload="auto" controls>         <source src="video/whoweare_hi.mp4" type='video/mp4; codecs="avc1.42e01e, mp4a.40.2"'>         <source src="video/whoweare_hi.ogv" type='video/ogg; codecs="theora, vorbis"'>         <source src="video/whoweare_hi.webm" type='video/webm; codecs="vp8, vorbis"'>         </video>     </div> <!-- end introright --> </div>

javascript

<script> $("video").on('play',function(){     $("#overlay").show(); });  $("video").on('pause',function(){     $("#overlay").hide(); });  $("video").on('ended',function(){     $("#overlay").hide(); }); </script>

css

#overlay {   display:none;   position:fixed;   width:100%;   height:100%;   top:0;   left:0;   opacity:0.8;   background-color: #282828;   z-index: 20;    transition: opacity .25s ease-in-out;   -moz-transition: opacity .25s ease-in-out;   -webkit-transition: opacity .25s ease-in-out; }   video {   width: 100%    !important;   height: auto   !important;   margin: 0 auto;   margin-top: 50px;   z-index: 999;   position: relative;    -webkit-box-shadow: 3px 3px 11px 0 rgba(50, 50, 50, 0.75);   -moz-box-shadow:    3px 3px 11px 0 rgba(50, 50, 50, 0.75);   box-shadow:         3px 3px 11px 0 rgba(50, 50, 50, 0.75); }

use fadein() instead of show(), , fadeout() instead of hide(). also, have remove display: none css , set default opacity 0.
