hand side of  the cart, with Gandalfs staff on the left. In the next shot, the  lantern and cloth have switched sides with the staff (which itself  moves back and forth between shots as Gandalf and Frodo travel into  the village). It would seem that the first shot has been flipped so  that the "road" bends round to the left to match the curve of the  road as Gandalf approaches Frodo in the next shot.
