If you have flash four you have to select what you want to un focus make it an MC. Then Coppy it and put it at ALPHA 20 and then just slightly move it off the 1st image. It will look like phase 2. continue. and it will look like phase 3 and do it about 5 more times and it will look like phase 4. This is the best unfocused effect i could do with flash 4. I hope i could help and this is what your looking for.
