I would like to make a camera effect, where the animation in the front (consisting of other symbols, that are moving around with frame by frame technique, and no tweening included) is blurred, and the one in the background is sharp, and then fading to the opposite.
I am aware, that I have to use filters with caution, as they might slow down the older computers significantly. But then I got this idea, to try and switch my Graphic Symbol to Movie Clip and turn on Cache as Bitmap. I haven't really used this feature alot, but I've heard that it is good idea to use on complex vector graphics, to save CPU power, unless I want to scale the symbol (in or out), which then would result in rastering/pixelating (where you start to see the pixels of an image, which looks pretty ugly).
So my actial questions are:
1). In what situation, do you use Cache as Bitmap?
2). Do you think that it would be a good idea to use Cache as Bitmap, for my Blur technique?
3). Is there anything else, you can tell about Cache as Bitmap as a whole: when to use it and avoid it.
I would have tested this my self, but I have no older computer (with slow CPU) to test the SWF on.
Thanks in advance
