None of the ground crew look to the FDO for clearance out from the helicopter and none of them look anywhere except at the undercarriage during the procedure. Judging by the twitching in the hover before landing and the movement in pitch as the groundcrew run in, I would say the conditions are not as benign as they look.
Before landing - the aircrew did not have direct comms with the ground crew under the nose - a simple intercom lead to the team leader would have been sufficient. Had the pilot sneezed or twitched and a crewman been injured, the posts here would be full of condemnation for not taking adequate safety precautions.
Just putting a Flight Safety Officer's opinion on the video, that is all.
