Locate the video you would like to include and copy the embed code. For youtube videos, this code is found within the "share" menu. For the video above, it looks like this:
<iframe width="560" height="315" src="https://www.youtube.com/embed/BrICsjnKPAg" frameborder="0" allowfullscreen></iframe>
If your guide is connected to a template it will need to be disconnected in order to edit the HTML. To unlock a guide from the html, click the lock icon next to the template and confirm that you would like to disconnect it from the template. Next we’re going to paste that same embed code that you copied in the previous step into the html tab.
You should now see a preview of the video and how it will render within the guide.
You may notice that the video formatting does not align perfectly with your guide. That’s ok though, as we can change that. To fix this, click on the layout tab and then adjust the width of your guide until it fits how you like. If you’re comfortable with CSS and want to go that route, you can adjust the additional settings from within the CSS tab.
