Create Masks from Edges
Posted: August 18th, 2008, 10:54 am
Here's a challenge (I think)!
Is it even possible to have AE create animated masks that are generated by visible edges?
I'll try to clarify. I'm using the Reshape effect in AE to warp certain elements in a shot to new positions. Reshape uses two masks and animates the shape of the pixels within them from mask A to mask B. Basically, I have to roto every element I want to shift.
I have Mocha and would like to let it do most of the roto work for me. The problem is, Mocha won't export animated masks to AE, just black & white mattes but I need animated masks to use with Reshape.
...So, can you write a script that would "see" the black & white edges of a matte and create an animated mask shape that follows it?
Either way, thanks for reading!
