I agree with you….should be easier….
but build it in the main 1st…so you can repo your fill in relation to the matte on top of it…
then nest the fill
then add the matte key to the nest clip ( on the main seqeucne..not inside it) last…
they really should add a pref in the track matte to have it be pre/post motion transform. that would solve it.
I can see plenty of cases where you want to do both types or work.
