Here is my syntax for a Youtube clip which gets an error. see screenshot
<iframe class="embed-responsive-item" src="https://www.youtube.com/embed/v=HdP0wb25_Lc?rel=0" frameborder="0" webkitallowfullscreen="" mozallowfullscreen="" allowfullscreen=""></iframe>
Any ideas welcome
Hey @AussieJohn,
Try using this, check if this is the same video you were trying to link too.
<iframe width="560" height="315" src="https://www.youtube.com/embed/HdP0wb25_Lc" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>Thanks - I also discovered you can use the share option on Youtube to find the embed code.
Yeah that’s where I got it from, after looking at your one. I wondered why your code looked like that. 
I just substituted the the URL for the default Vimeo one
