Please look at this jsfiddle, might gear you in the right direction, but it's kind of hard since I don't have any html to look at:
http://jsfiddle.net/M8c3F/
I removed the hover, because when fading out and in, it was difficult to get the elements back. So I replicated that behavior with mouseenter and mouseleave instead.
script:
$(function() {
$(".tooltip").mouseenter(function() {
$("> .vidOver", this).stop().fadeIn(750); //child class of (this element)
});
$(".tooltip > .vidOver").mouseleave(function() {
$(this).stop().fadeOut(500);
});
});
html code:
<div class="tooltip">parent container 1
<div class="vidOver">child container 1</div>
<div>child container 2</div></div>
<div class="tooltip">parent container 2
<div class="vidOver">child container 2</div>
</div>
