Hi Mads,
I appreciate the input and I believe you’re completely right. I’ve looked into AE and it has the extend script functions to do exactly what I want with some fiddling. Mocha may too, though I personally don’t know much about it.
Unfortunately this is one of a series of projects to improve quality of life and streamline the editing cycle centered specifically for Premiere Pro to avoid the need to hop between software.
It is a bit unfortunate, the Adobe forum led me to believe that turning to C++ plug-ins is the only choice which would be quite the setback and potentially not much of an improvement to manually clicking through the steps for an alpha matte layer.
Still, I appreciate your suggestions
