Today I shot the only walking scene that I needed to do where the puppet crossed from one side of the screen to the other in a straight line. I needed the camera angle to be straight on with just his lower body showing. As he is a tie down puppet I needed to angle the camera carefully so that it didn't show the tie down floor that the puppet was walking on but just the floor that was directly behind him, this took me about half a day to set up.
I scanned in an image of a walk cycle from Richard Williams 'animators survival kit' which I then rotoscoped into my work screen in Stop motion pro so that I had a rough guide to help me know how to move the puppets legs.
