Hey litetaker, to embed videos from YouTube, copy the code that YouTube provides for “embed.”
Edit the page/post you want to embed the video on, and make sure you’re viewing the “Code” or “HTML” (depending on your version of WP) panel. Now, when you paste the code from YouTube, delete the very last “object” tag.
For example, here’s some YouTube embed code for one of my recent videos.
<object width="425" height="344"><param name="movie" value="https://www.youtube.com/v/pnfWwGhYr9Q&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="https://www.youtube.com/v/pnfWwGhYr9Q&hl=en&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
WordPress doesn’t like this. Delete the “</object>” term so you actually paste this code:
<object width="425" height="344"><param name="movie" value="https://www.youtube.com/v/pnfWwGhYr9Q&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="https://www.youtube.com/v/pnfWwGhYr9Q&hl=en&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed>
Hope this helps!
