Hi Anthony,
Are you trying to add the Video to a page using Dynamic Tag Management ?. As this particular forum is dedicated for queries regarding Adobe Marketing Cloud- DTM product. However as per our understanding ,you can add the You Tube video in an Object Tag without using Iframes. Please refer the code below for more information.
<object width="640" height="360"> <param name="movie" value="http://www.youtube.com/embed/yt-video-id?html5=1&rel=0&hl=en_US&version=3"/ <param name="allowFullScreen" value="true"/> <param name="allowscriptaccess" value="always"/> <embed width="640" height="360" src="http://www.youtube.com/embed/yt-video-id?html5=1&rel=0&hl=en_US&version=3" class="youtube-player" type="text/html" allowscriptaccess="always" allowfullscreen="true"/> </object>
Replace yt-video-id
with your video id
Thanks & Regards
