Camera Knock

I spotted in the Episode "Merry Christmas,Father Christmas" towards the end fake snow was dropped in front of the camera to give us that winter feeling, if you watch just as Nora goes back into her house, it looks like the camera was knocked as the scene seems to jump,was was probably due to whoever was in charge of sprinkling the snow in front of the lens

I was watching an early show from the Blamire days. They were filming the closing scene in the hills and apparently it was a real windy day as everyone and everything was being blown around and even the camera was shaking.
