video object code overwritten by wp

Hi,

I recently tried to include a video object schema code in wordpress post and it works fine when you look at it but when I went back to look at the code, the code was overwritten to regular iframe code.
How can i stop my video object code from being overwritten by wordpress editor??

Thank you!
FYI – here’s the code I want to include –
<div itemprop=”video” itemscope itemtype=”https://schema.org/VideoObject”&gt;
<meta itemprop=”description” content=”ENTER VIDEO DESCRIPTION HERE”>
<meta itemprop=”thumbnailURL” content=”ENTER THUMBNAIL URL HERE”>
<meta itemprop=”duration” content=”ENTER DURATION HERE”>
<meta itemprop=”embedURL” content=”https://www.youtube.com/embed/ENTEREMBED CODE HERE”>
<link itemprop=”url” href=”ENTER YOUTUBE URL HERE” rel=”author”/>
<span itemprop=”name” style=”display:block;”>ENTER POST TITLE HERE</span>
<div class=”embed-container” style=”text-align: center;”><iframe src=”https://www.youtube.com/embed/ENTER?EMBED CODE HERE” width=”730″ height=”411″ frameborder=”0″ allowfullscreen=”allowfullscreen”></iframe></div>
</div>
