The default gray video play button in vBulletin 5 looks dull and bland. Make it alive without using another image by using the below CSS.
Here's a screenshot of before and after:

Code:
.videothumbnail .videothumbnailoverlay {
width: 50px;
height: 36px;
border-radius: 13px;
border: solid 1px #f00;
background-image: none;
background-color: #f00;
position: absolute;
left: 50%;
top: 50%;
margin-left: -26px;
margin-top: -18px;
box-shadow: 2px 2px 8px rgba(0,0,0,0.5);
}
.videothumbnailoverlay:before {
content: '';
display: block;
position: absolute;
left: 20px;
top: 11px;
height: 0;
width: 0;
border-top: solid 6px transparent;
border-left: solid 5px #333;
border-bottom: solid 8px transparent;
border-left: solid 14px #fff;
}
.videothumbnail .videothumbnailoverlay:hover,
.videothumbnail:hover .videothumbnailoverlay {
background-image: none;
border-color: #e60000;
background-color: #e60000;
}
