you can use the blur filter in flash to tween a blur.
but you can also use an alpha cross-fade from your non-blurred to your blurred image and back
Thanks for your reply. My problem now is - since I am using text, doesn't this mean that I can't use a shape tween? (I tried and it would only let me use motion or classic tween) Is there a way to get around this?
Just bumping this up
you can use timeline tweening or actionscript tweening but not both for the same object at the same time. if you're shape-tweening that's easier to do with the timeline (for most people).
you should be able to timeline tween your shape (create a movieclip of that tween) and apply a blur tween to that shape-tweened movieclip.
