Animation in Photoshop - Blur.

For this animation, I was asked to make the letters blur. To do this, there needed to have four frames. One with the letters at top, then at the bottom, then blurred and then back at the top.
There was also two layers, the letters normally and then one blurred.
To hide one of the layers so it doesn't overlap and look bad, the right layer had to be hidden.
The extra frames were added later.
