Check meta data before it is published

I am using a church theme and a custom post with its own meta data.

What i want to do is that if a sermon post is published, WP will check whether someone included a video URL. If they do, check the Video Sermon category. If they do not, do nothing.

My problem is that this code only works when the person click on Save two times. I suspect it is because my codes is pulling data from the database. Since the first time someone posted, the data is not in the DB yet. Can someone showed me how to test the meta data before it is published or written in the DB?

Here's my code:

//Sermon post include Sermons category function add_sermons_automatically($post_ID) {

//check video

$video_info = get_post_meta('imic_vimeo_video', $post_ID);
 $video_info .= get_post_meta('imic_mp4_video', $post_ID);
 $video_info .= get_post_meta('imic_webm_video', $post_ID);
 $video_info .= get_post_meta('imic_ogg_video', $post_ID);
 $video_info .= get_post_meta('imic_youtube_video', $post_ID);

if (!empty($video_info)) {
    $sermons_cat = array(28);
    wp_set_object_terms( $post_ID, $sermons_cat, 'sermon-category');

} add_action('publish_sermon', 'add_sermons_automatically');

Thanks, Cliff
