It is double dummy, and would be easy for any advanced player to solve single dummy, this is clearly meant for beginners. I think most people, seeing the double dummy would solve it very quickly and not need to see the remainder of the movie to know what the two tips are.

I have to comment that the presentation style could use some improvement. First, double dummy was probably a mistake. Second, the play of so many tricks all on the same movie frame is a ackward and will be impossible for the target audience to follow. Third, the text, in places, was too long on one frame. And saying ♠ for spade and Ace♠ for ♠A or Spade Ace was too. Still the lesson on reading declarer's intention (or counting tricks) is a good one for the targeted pool of players.
