I think you need to add that semicolon
var popcorn = Popcorn( "#video1" );
popcorn.play();
apart from that you also need that div with id image
as you have mentioned it in target.
add like this:
<div><video id="video1" height="400" width="800" controls>
<source src="videos/Makeurbed.mp4">
</video></div>
<div id="image"></div>
also remember that the mp4 format is not supported by all browsers and viceversa , it is always better to add more file formats.
like this :
<div><video id="video1" height="400" width="800" controls>
<source src="videos/Makeurbed.mp4"></source>
<source src="videos/Makeurbed.ogv"></source>
<source src="videos/Makeurbed.webm"></source>
</video></div>
<div id="image"></div>
also add the height and width inside the video tag , not inside source tag
