I would like to know if pscs4 or 5 extened) can do a traveling shot of a background and on other layers have walk cycles. Also with the walk cycle and backgrounds - should they be made into smart objects in case they need to be scaled.

I am looking for information on how to use pscs4 or 5 to make classical animations (Disney style)(that is scanning hand drawn character cycles and hand painted backgrounds so not looking to use vectors at this time for them but that does lead into questions about using smart objects for scaling the characters and backgrounds) - links to tutorials, books, videos (youtube, etc) free or commercial products.
