Once you upload your videos to Youtube, it is possible to combine your short videos into a PLAYLIST.  This is an option available on YouTube.  Then with the "Playlist" box checked on YouTube, you can click the Share button and get the short link for the Playlist to send to us to connect to your ad. 

We can embed the PLAYLIST link on our site and it will play all of your selected videos consecutively.  This also allows you to change what is showing in your Playlist from the YouTube site.
