Creating a mask from a png photo
on Nov 26, 2010 at 9:25:15 am

Hi...im new in this forum and its cool to be here!

I need your help in creating a simple mask ....but i dont know how!

I have a png logo on one layer and fire on the layer below
What i need to do is to mask the logo so that fire appears only on the logo, and then render FLV RGB + Alpha to import the whole thing in Flash without background...just the logo..

How do i mask the png?

Thanks

I'm a bit confused by your question, but if I get it right, then this is what you need to do:

Masking the logo- one way is to cut the logo in PSD and import the layer in AE. Another way is to cut a mask in AE itself.
I recommend the first version. This way you can use the logo layer (duplicate it) and apply track matte to the fire layer to get the fire to be inside the logo shape.

Expost as swf or as Flash project if you have CS5.

I was just searching for the same thing. This was the solution that worked for me:

Select your png layer in your comp and then go to -
Layer > Auto-trace...

Once you answer a few questions it creates a new layer called Auto-traced[xyz].png
