Alter quality during heavy animation

Hi there,

I recently read an article in British mag ‘Computer Arts’, in which was described how to alter the quality of a movie during heavy animation. Well, now I need this trick, but I don’t have my mags at hand, and I need it quite urgently…

So does anyway know how to do this? I have a large movieclip (full of vectordrawings) and I need to move it over the screen (kind of scroll movement), but I want to set the quality to a lower value during this scroll.
Any ideas?

Thanx in advance,
