I like the part where the camera zooms in but isn't pointed at the spot where things are happening and then slowly pans until it's in frame. Honestly, looking at the video again, I'm sort of curious as to what exactly is going on with the camera; it seems handheld, but it's also moving in sync with the piece of equipment with the wedge/blade on it. Are they standing on a platform that's fixed to the other equipment?
