I can’t center the video

Question

Guys I’m trying to center the video, trying to use the margin:0 auto; there’s the possibility of me positioning through the padding or something like that, I made the other page exactly like this and was normal, but now I need to put again and will not, have to help me.

HTML

<div id="corpo">
      <h1>Seje Bem Vindo(A)</h1>
      <video controls>
          <source src="img/transpiedade.mp4">
      </video>            
</div>

CSS

#corpo video{
    width: 750px;
    margin:0 auto;
}

Answer 1

The margin: 0 auto; will only work with block elements. Then just add display: block; on the tag video:

#corpo video{
    width: 750px;
    margin:0 auto;
    display: block;
}

<div id="corpo">
      <h1>Seje Bem Vindo(A)</h1>
      <video controls>
          <source src="img/transpiedade.mp4">
      </video>            
</div>
