When making a name animation, you have to open up photoshop, click file, click new, and make the width 600 and the length 150 (pixels).
after you create the background, create a text layer and type whatever you want.
after you type your text layer, right click on the text layer and rasterize type. This should make an animation layer, not a text layer.
Next, use the erase tool to erase small parts of the text.
Erase small parts and drag the layer to the "create new layer" tool.
continue erasing and duplicating.
when you are done erasing and duplicating, at the top of the screen, click window and make sure timeline is selected
when the timeline shows up, select all of the layers and click "create frame animation" nd cick the box at the top right of the timeline and click "make frames form layers.
once you have created the frame animation, click on the box at the top right of the timeline and choose to reverse frames.

once you have reversed the frames, you are done!
