This is a video of a sequence of ballet positions, with both arm and feet. There are five arm positions and five feet positions, so recording this as a tuple gives an ordered set of 25 elements, which correspond to letters. Reading off the positions yields the clue phrase READ OFF LEGS IN BINARY TO FIND ANSWER. Looking back at the video, between each positions either the left or right leg is moved to transition between positions. Recording this, converting to binary, and reading every five digits as letters yields KARATE, the answer.
