<!DOCTYPE html>
<html>
<head>
	<title>TESTE</title>
<link rel="stylesheet" type="text/css" href="estilo.css">
</head>
<body>

	<div class="video"> 
		<div class="moldura">
			<img src="https://lh4.ggpht.com/SKQHLsT8xsNpXeL5si4bBqSNqdy8Qbvzk15J3qWTp55AnnkbNO6-vBJhIBTQxyq16YE=w300">
		</div>

	</div>
	
</body>
</html>

Have you tried using flex boxes?

EDIT: As per comment, no i didn't know about using "align-items", works well, I've edited the snippet accordingly! :)

.video{
display:flex;
justify-content: center;
align-items: center;
flex-direction:column;
height:250px;
background-color: peru;
}

.moldura{

}

.moldura img{
 height:50px;
 border:1px solid black;
}

<!DOCTYPE html>
<html>
<head>
	<title>TESTE</title>
<link rel="stylesheet" type="text/css" href="estilo.css">
</head>
<body>

	<div class="video"> 
		<div class="moldura">
			<img src="https://lh4.ggpht.com/SKQHLsT8xsNpXeL5si4bBqSNqdy8Qbvzk15J3qWTp55AnnkbNO6-vBJhIBTQxyq16YE=w300">
		</div>

	</div>
	
</body>
</html>

添加了行高css属性。

.video{
width: 100%;
height: 500px;
background-color: peru;
position: absolute;
}

.moldura{
	display: block;
	width: 50px;
	margin:0 auto;
    line-height:500px;
    height:100%;
}

.moldura img{
	width: 50px;
    vertical-align:middle;
}

<!DOCTYPE html>
<html>
<head>
	<title>TESTE</title>
<link rel="stylesheet" type="text/css" href="estilo.css">
</head>
<body>

	<div class="video"> 
		<div class="moldura">
			<img src="https://lh4.ggpht.com/SKQHLsT8xsNpXeL5si4bBqSNqdy8Qbvzk15J3qWTp55AnnkbNO6-vBJhIBTQxyq16YE=w300">
