To add a video to your video gallery or showcase, you'll need to copy the URL of the video from YouTube. The URL is simply the address of the video on the YouTube web site.
To find your video's URL, first find the video on YouTube.
On the video page, you'll see two boxes in the upper-right corner, labeled URL and Embed. The code in the URL box matches the code you'll see in your browser's address bar.
Double-click to select the URL in either the URL box or your browser's address bar, then copy that code by pressing Ctrl and C on your keyboard (Command+C on a Mac). You'll paste the URL code into Site Solution to add your video.
