Easiest way is probably just for me to show you with this 7 MB H264 .mov  movie
Right click, save as:

At the very beginning I move the head into position where the right ear is just against the document window border, then proceed to move various sliders. The head is clearly moving, to varying degrees.
Later on I slide down to the section with the nose morphs I made yesterday and slide them around and you can see the head is not moving.
