Ever wonder how the ATP gets ahold of all those slick promotion materials of players for every single event on the calendar? Over five days in Melbourne, the pros on the men's tour take part in a video and photoshoot with the ATP World Tour.

"I think it's important to do for the promotion of all the events around the world," Roger Federer said. "It doesn't take much time. It's good fun. I like to do it every year. I'm happy with the result."

The ATP takes special care in not wasting players' time, with Sam Querrey calling it a "well-oiled machine" that takes about 20 minutes.

Speaking of oil, the behind the scenes footage shows Hyeon Chung literally getting oiled up ahead of his turn in front of the camera. It's all in a good day's work on the ATP tour.
