Short answer: you can—there are a few practical approaches depending on the kind of blur you want (motion streaks, soft/Gaussian blur, or depth-of-field). Several replies here (notably , and ) pointed out that people often reach for external tools or tricks; below are concrete, version-agnostic techniques you can apply inside Flash workflows plus notes on tradeoffs.

For motion blur (moving objects)

  • Create a short trail of the same symbol duplicated along the motion path, each copy slightly offset and with progressively lower alpha. Keep only a handful of copies (3–6) for performance. Subtle scale/rotation changes sell the effect.
  • If your Flash build supports runtime filters, apply a small blur to the trailing copies rather than the original to soften edges without blurring the whole stage.

For soft/Gaussian blur (evenly fuzzy edges)

  • Use the engine’s blur/filter API if available and apply it to a MovieClip or bitmap snapshot. Example (ActionScript):
import flash.filters.BlurFilter;
var bf:BlurFilter = new BlurFilter(8, 8, 1);
myClip.filters = [bf];
  • If runtime filters aren’t available or are too slow, render a blurred version of the artwork as a bitmap (pre-render) and swap it in at runtime.

Advanced / programmatic

  • For full control, take a bitmap snapshot and run a convolution/gaussian pass on the BitmapData (where supported). This gives better quality but costs CPU and is more code-heavy.

Performance and troubleshooting

  • Blurs are expensive: limit the blurred area, reduce filter quality, and convert complex vectors to bitmaps when possible (cache-as-bitmap) to improve speed. If a filter has no visible effect, try applying it to a bitmap copy of the clip—some vector nesting or player versions suppress runtime filtering on raw vectors.

These options let you choose the right tradeoff between visual quality and runtime cost for the blur you need.

Well, I am learning flash also, and as far as I know,
you can't.
well, in flash at least. Yeah, flash is NOT the best image creation program there is. Flash is an animation program. If flash could like, merge with photoshop that would be bliss. pure unadultered bliss.
But unfortunately we are doomed to have to make do with what we are given.
Your best bet is to goto photoshop and make your image there if you REALLY have to have a blur in your animation, I mean, DRAW out the blur --kinda like what they do in cell animation.

Look at other flash animations. Do any of them have a blur?

Sorry I couldn't help,

That depends on what type of blur a general blur like a photo out of focus or a motion blur? But both can be done in flash. I was told you couldn't make a browser shake but I proved them wrong by not only making my browser window shake but doing it from flash too :-)

P.S. Check out www.FlashKit.com goto the forum and enter the newbie form and ask in there and if you are lucky the king Iaskwhy will answer your question and if he is not about goto the Coffee Lounge and see if Subway is about :lol:

whoa, how did you make the browser window shake?

whoa, how did you make the browser window shake?

The line pf code in your flash movie is getURL("javascript:shake_x(5)")
place this when you want the browser to shake.

basicly this activates Javascript in the HTML page, have a look at the javascript at the top of the HTML page without this it wont work.

But remember after a while the shaking of the ebrowser gets annoying so don't do as I originally did!!!! I had a button at the top of a flash site that said MENU when you clicked it the navigation would animate onto the screen then shake the browser (With a thunder sound), when you clicked a link on the navigation it animated out of shot.

But havin g to watch the browser shake and hear that sound everytime I wanted to change page was giving me a headache I would suggest using this code in a flash intro or something that would be appropriate.
