Antialiased cutscenes

From the dev journals I have read it seems apparent that anti-aliasing slows down older systems, particularly when showing cutscenes. But if cutscenes are prerendered, they should already have antialiasing, so why not just turn off antialiasing when showing cutscenes? Is there something with the graphics engine that makes it difficult to switch antialiasing on and off?

Well, I guess it is a resolution problem: The cutscene are surely set at specific resolution, which is surely lower than the resolution at which you will play the game. So if the movie needs to be stretched, meaning anti-aliasing may be useful

Full-screen antialiasing occurs throughout. I.e. it's a DirectX thing.  It's not needed for the cut scenes but it's not easy to turn it on and off on the fly like that.
