It's a bit of both:  the Ken Burns Effect commonly combines a zoom with 
a pan, so emulating it precisely would require changing the image's rect 
-- a much more computationally expensive action than moving the image.

I wonder if Trevor's been reading this thread and has come up with an 
external to hook into QT transitions while executing 
computationally-expensive Transcript without impairing either....
(I can dream, can't I?)
