Is there a way to use the feather tool on imported AE Mocha keyframes with out having to adjust them manually one at a time? Is there a way to have access to JUST the Feather Tool key frames so I can run the KeyTweak script just on that portion of the key frame. Any help or insight will be great!
No. Mask keyframes are compound data. There is no way to manipulate just one aspect of them globally.
