First, thanks for the shout out (1710) - we're lucky enough to have a subteam of students who are passionate and interested in video production.
One video that REALLY stood out to me (although it was already mentioned) was 2974, who won RCA at Orlando this year.
Team 2468, Team Appreciate, also has a pretty good Chairman's video.

The Championship Chairman's recipient from last year, 27 Team Rush put together an amazing video, but I would also suggest that anyone interested also check out 1114 Simbotics' Championship-winning video from 2012, and some of the other Chairman's Award resources that 1114 has produced.
