Hi all, I'm undertaking a new project. The idea is to mask out parts scenes, for example the sky, and replace it with something else.
In the attached video clip sample, my process is:
Apply an Alpha Matt to original footage, manually mask the Alpha Matt, to remove the sky. Then, frame by frame, animate / track the mask, so it stays aligned with the alpha matt / original footage, during the actual camera move.
I'm new enough to After Effects, so any tips on how to improve this technique would be great. The most important part of the process is the accuracy of the mask, as the camera moves.
My approach feels a little stone age though?
