In this tutorial we will create a blur effect that works great with Text or Images. I recommend using this as roll over movie for a button. You can find a tutorial on how to make an animated Button roll over Here. Before embarking on this tutorial you should have some basic Flash Knowledge.

Launch FLASH and Photoshop and make sure your frame rate is at 30fps in Flash. You can edit the movie properties by going to Modify>Movie . Lets begin...

Step 1: Photoshop Tricks

• We will first begin this tutorial in Photoshop. Start a new image and make it no more than
  334x150 in dimension size.
   

• Now, Using the Text tool Type in the text you plan to use in your flash movie(be sure to remember the Font and font size you are using). In this case we will use the words "motion blur" and a font size of 20. Merge the text layer with the backroundlayer by selecting the text layer and pressing CTRL+E.

Step 2: Blurring in Photoshop
Now that you have your text ready its time to blur it. Go to Filters>blur and select motion
blur. Bluring the text by 14 pixels for a medium sized blur. If you want to give the illusion that your
text is moving at even higher speeds, simply adjust the settings to Blur the text by 24 or 34 pixels.
Now that you have the desired blur save the image. (set the Quality setting between 2-4)

Step 3: Back to Flash
Switch to Flash. Type in the same word we used using the same Font and Font Size as before.
Make the text into a symbol by pressing F8. You can make the text a button or movie clip depending
on what you need. For this demonstration we will make it into a graphic. Next, import the blured image
convert it into a graphic symbol and place it in its own layer. Name the new layer "imported text". and
Name the Layer that contains our Flash text "Flash text".

Step 4: Keyframes
Line up the Blurred image so that its lined up with our Flash text. In the "Flash Text" layer, make a key frame on frame 4, and move the flash text graphic to the left. Now, select the "Imported text" layer and do the same. On frame 4 of the "flash text" select our flash text. go to Modify>instance and set the alpha to 0.
 
On frame 1 of the " imported text" layer set the Alpha of our imported image to 0. Now add a blank key frame on frame 5 of the "flash text" layer. Add a keyframe on frame 9 of the "imported text layer" and move our imported image all the way to the left so that it is off of the stage.

This is our Finished movie. Experiment and have fun:
