Steadicam

Steadicam is a piece of equipment used on cameras allowing it to be seperated from the operaters movement. This means it creates a smooth surface even on rough surfaces. In the above example, a steadicam is used from the beginning of the clip to around 0.05 or 0.04. I believe it was used here in order to create a smooth surface and therefore makes the shot more professional than what would've been created with a handheld camera.
