HTML & CSS Am I Right Here?

[Sniper Man]

Is the following HTML code for displaying the top video of my blog's video pages correct? I am particularly interested in knowing if I have implemented the mainEntityOfPage itemprop tag of schema.org correctly.

<meta itemprop="duration" content="PT1M33S">
       <meta itemprop="thumbnail" content="https://thuitamaina.com/video_thumbnails/33.jpg">
       <meta itemscope itemprop="mainEntityOfPage" itemtype="https://schema.org/VideoObject" itemid="https://thuitamaina.com/videos/33.mp4">
<video class="blog_images" poster="https://thuitamaina.com/video_thumbnails/33.jpg" controls controlsList="nodownload" oncontextmenu="return false">
      <source src="https://thuitamaina.com/videos/33.mp4" type= "video/mp4">
      </video>

<meta itemprop="duration" content="PT1M33S">
       <meta itemprop="thumbnail" content="https://thuitamaina.com/video_thumbnails/33.jpg">
       <meta itemscope itemprop="mainEntityOfPage" itemtype="https://schema.org/VideoObject" itemid="https://thuitamaina.com/videos/33.mp4">
<video class="blog_images" poster="https://thuitamaina.com/video_thumbnails/33.jpg" controls controlsList="nodownload" oncontextmenu="return false">
      <source src="https://thuitamaina.com/videos/33.mp4" type= "video/mp4">
      </video>

Here's my latest code for the video. Please ignore the one above and tell me whether the one below is right, especially if I've put the mainEntityOfPage itemprop on the right place:

<span itemscope itemprop="mainEntityOfPage" itemtype="https://schema.org/VideoObject" itemid="https://thuitamaina.com/videos/34.mp4">
  <h2 itemprop="name">
    <font color="blue">
      <div align="left">O Lord My Love</div>
    </font>
  </h2>

  <div class="post_info">
    <div class="post_date">
      A Video
    </div>
    <div class="post_author" itemprop="author" itemscope itemtype="https://schema.org/Person ">
      <span itemprop="name">by <i>Thuita J. Maina</i></span>
    </div>
    <time itemprop="uploadDate" datetime="2022-09-06T00:00:00Z">
      <div class="post_comment">on Sep 6, 2022<br></div>

  <div class="post_body">
    <div class="container">

    </div>
    <div>
      <span itemprop="duration" content="PT1M33S">
        <meta itemprop="thumbnailUrl" content="https://thuitamaina.com/video_thumbnails/34.jpg"/>
        <link itemprop="embedUrl" href="https://thuitamaina.com/videos/34.mp4" />
        <video class="blog_images" poster="https://thuitamaina.com/video_thumbnails/34.jpg" controls controlsList="nodownload" oncontextmenu="return false">
          <source src="https://thuitamaina.com/videos/34.mp4" type= "video/mp4">
        </video>
      </span>
      <i><figcaption></figcaption></i>
      <br><br>
      <span itemprop="description">
        In the video above is another hymn that I have produced. It's about asking God - who is our love, strength, tower, hope and joy - to heal our wounded minds and strengthen us with heavenly grace. I urge you to listen to the hymn and then send me your feedback on how to find it. Happy listening!

        If you've enjoyed listening to the hymn above, you might also enjoy another one on
        "<a href="https://www.thuitamaina.com/selected_video.php?Index=17">O Lord My God</a>"
        that I produced more than a year ago. Just click on that link in blue to dive straight into the hymn.

Hi there,
I know nothing about the mainEntityOfPage meta tag, so I can't tell you if it's correct or not.

Just by looking at your code I can already see that you seem to have used closing </span> tags instead of </div> closing tags toward the end of the code.
Putting your code in the W3C Validator highlights a lot more errors.
