            ],

 

추가한 부분은

Html.Allowed항목에서 iframe[src|width|height|allowfullscreen],

'HTML.SafeIframe' => true,
'URI.SafeIframeRegexp' => "%^(http://|https://|//)(www.youtube.com/embed/|player.vimeo.com/video/)%",
'HTML.FlashAllowFullScreen' => true,

 

allowfullscreen은 말그대로 전체보기 허용할거면 추가하고, 안할거면 지우고.
