Embedding a video via script tag versus iframe

Question

I've sucessfully embedded a youTube video before via an <iframe>, but I am having difficulty embedding a video through a <script> tag. The third party video platform that I am having to go through only offers this method of embedding so I am stuck with trying to come up with a workaround.
Here's my code (inserted into document.compositionReady):
var familyVideo = document.createElement('script');
familyVideo.type = "text/javascript";
familyVideo.src = "URL HERE";  // note: URL is propietary so I cannot share that with the forum
sym.$("familyVideoWrap").append(familyVideo);
I know that with youTube videos, the code is something as follows:
var youtubevid = $("<iframe/>");
sym.getSymbol("intro2").$("videoContainer").append(youtubevid);
youtubevid.attr('type', 'text/html');
youtubevid.attr('width', '387');
youtubevid.attr('height', '218');
youtubevid.attr('src', 'URL HERE');
youtubevid.attr('frameborder', '0');
youtubevid.attr('allowfullscreen', '0');
I've tried both methods (swapping <iframe> with <script> in the second method), and neither seem to work. Is there some sort of hold up that I am not aware of that allows us to embed <iframes> into our Edge elements, but not <script> tags? Any help is greatly appreciated.

Answer 1

Think what differs in the code there.
The 3 file types, the width and height - Custom fields.
The list layout of web apps is that code with those elements the tags.
Then you can insert module into template or page as you need.
Say you have a home page video. Classifcation of home so a client can easily change the video in and out via web app items...
Heaps of options.
