Yes, that is how I usually cover things if the situation is simple and there are no lighting changes, but what I’m trying to figure out here is how to do this without freezing the frame in order to create the mask. If I just create a patch using a clean portion of the surface (freezing time in order to do so,) then it will not blend in with all of the light changes occurring on that surface.
I just discovered “Track Mask”, which is very close to what I’m looking for, but it still feels clunky. I want to be able to track a clean section of wall and apply the mask to those tracking points to create the patch, and then pickwhip that patch onto a different tracking point/null object.
