You Tube embedding w/ new format

[mockingbird812]

So, really cool that there is a “You Tube” button for putting our videos in our posts, but I must be doing something wrong. I copied the url from the video I want to embed and then placed the “you tube” markers on either side of the url (using the “you tube” button), but when I preview it, the post is blank. I heard that the “s” in https... needs to be deleted sometimes which I also tried. Any help is appreciated.
