Transparency in animation help.

I need some help adding transparency to an animation that I have done. I need to do it as though I have added a clipping mask above the animation as the pixels behind where I want it to be transparent are needed for the animation effect.

Let me just put it another way to try and explain better.

So I have the animtion and just want to put the transparency over the top, kind of like adding a layer over the animation and cutting a hole in it so you can only see the animation where the holes are.

Do you mean a mask?
Would a layer mask help?

If you are willing to take a look You can down load a sample here uk.geocities.com/di22y@btinternet.com/images/thisone.zip It is the white parts that I want to make transparent it is in a .psd created in windows

Ok corect me here, if all you want is "Dizzy" here is how you go about it

Select layer 3, then Ctrl/click the layer

goto Select then inverse

now goto each layer, (for some reason i had to double click t bring up the properties then cancel) and then hit delete for each layer.

this will give you a transparent image. Save as .gif and your done.


Hope this helps.
