Check which type of validation you have selected for the youtube video field. Firstly I have the type “website url” and the url sent to the function um_youtube_id_from_url($url) for getting video id wasn`t pure web url, it contains html tags.
So, I created action for custom field validation and put it in function.php:

add_action('um_submit_form_errors_hook_','um_custom_validate_youtube_url', 998, 1);
function um_custom_validate_youtube_url( $args ) {
	global $ultimatemember;
	$pattern = '/^(http(s)?:\/\/)?((w){3}.)?youtu(be|.be)?(\.com)?\/.+/';
	$result = preg_match($pattern, $args[video], $matches);
  	if (!$result) {
		$ultimatemember->form->add_error( 'video', 'This text is not relate to youtube url.' );
	}
}
