Youtube URL in custom field

I have a database of entries, each is a post. There is data in each post in a custom field, one of which is “video” which has the youtube url in it.

Im trying to get the url to echo in my loop,

<?php  if((get_post_meta($post->ID, "video", true))) { ?>

<p><span class="youtube"><iframe title="YouTube video player" class="youtube-player" type="text/html" width="425" height="344" src="https://www.youtube.com/embed/<?php echo get_post_meta($post->ID, "video", true); ?>	?wmode=transparent&fs=1&hl=en&modestbranding=1&iv_load_policy=3&showsearch=0&rel=1&theme=dark" frameborder="0" allowfullscreen></iframe></span></p>

<?php } ?>

the $video is not outputting anything. What am I doing wrong?
