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, 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 that link on our site and it will play all of your selected videos consecutively. It would help to send a note along with the video link that you want to use the video as a playlist so we know that you are not sending the playlist accidentally.
