Depending on the argument passed in url go to specific content type
Use hook_menu in custom module to achieve this using below code !
Change the links of Add Details to "goto/video" means full url will be localhost/drupal/goto/video

function yourmodule_menu() {
    $menus['goto/%'] = array(
        'title' =&gt; 'Just Redirect',
        'page callback' =&gt; 'drupal_redirect_to_content_type',
        'page arguments' =&gt; array(1),
        'access arguments' =&gt; array('access content'),
        'type' =&gt; MENU_CALLBACK,
    );
    return $menus;
}

function drupal_redirect_to_content_type($type) {
  drupal_goto("admin/structure/types/manage/" . $type);
}


Otherwise,

Instead of above what you can do it directly give Add Details link to admin/structure/types/manage/ . $type instead of drupal/$type
