The menu settings changed are going to be minimal, just stuff that makes sense for movie shooting like preventing beeps from sounding off during a recording, but the functions can be found on page 24 as the manual says and the changes are going to be again mostly just what makes sense for video recording, like that it will use a movie file format instead of a still image format but some things will also change just by the nature of the difference between the P mode and whichever other mode you were previously on. You can press the [FUNC.SET] button on your camera to see that functions list and make any adjustments you would like as well.
