Subbing a MP4 for a jpg

[motuiti]

I use the below code which crops an image to the rounded corners of the table border. How would I change the code to use a MP4 instead of a jpg as background ?


<TABLE BORDER=0 BORDERCOLOR=00B201 width=300 height=200>


<TR>
<TD>


<style type="text/css">
#table1 {
border:3px solid #00B201;

-moz-border-radius:25px;
-webkit-border-radius:25px;
width:300px;
height:200px;

background-image: url('ChristmasBackground.jpg')
}
</style>
