Tracked and plotted the movements of Donald Trump and twenty-one other dancers at the Salute to Our Armed Services Ball during his inauguration on January 20, 2017.

The tip of the nose was chosen as the tracked point; tracking the hands and feet are the obvious choices for any sort of physical movement, but there were a lot of close-up headshots in this footage and the hands and feet were only infrequently visible. The nose provided a more consistent point and reflected the overall motion of their bodies, and also the interaction with others on the dance floor.

The CNN footage of the ball was used. Black lines outline the text boxes that were present on the screen during the broadcast. The footage was 8 min, 6 seconds + 17 frames – 30 fps. The total number of frames in the video is 14,597.
