Blur Effect in Flash
In this tutorial we will learn how to use the built-in blur filter to blur an image. The effect is rather
simple and easy to understand.
Step 1: Create a new flash document and go to File>Import>Import to Stage and select the
image you want to use. In this tutorial we will use the image below:
Step 2: We should resize our document to fit with the photo, so press Ctrl-J to bring up the
Document Properties box and select Match: Content option. Our document will auto resize to fit
with the photo
Step 3: Click on the photo and change it to a symbol by pressing F8, in the Convert to Symbol
box select Movie Clip type to convert it to a movie clip
Step 4: Click on frame 40 of the Timeline and press F6 to insert a new keyframe there, this will
make our image totally clear at frame 40
Step 5: Now return to frame 1 by clicking on it, then click on the photo (now become a movie clip)
and press Ctrl-F3 to bring up the Properties panel if it doesn't show up. Click on the Filter tab and
click on the Plus icon (+) then select Blur
Step 6: The Blur options appears, set Blur X and Blur Y to higher values (80%, for example). You
can also set a suitable quality here
Step 7: Next, right click on any frame between 1 and 40 and select Create Motion Tween. Now
you can press Ctrl-Enter to test your result. It is simple, right?
Step 8: This step is optional: we should make the last frame (the "clearest" frame) last a bit longer,
so insert a new keyframe at frame 45. It means that frame from 41 to 45 will copy frame 40, make
our clear photo last longer to see!
In conclusion, we can only use the Blur effect after convert it to a movie clip and we apply it to the
first frame then we "create motion tween" to activate the process!
