I thought that would be the answer but it appears not – so I put two FX before the pan crop and they affected the whole clip – so far so good. I then put one after pan crop and did a mask.
When I then said “mask – apply to fx “YES” – ALL the fx both before and after the pan crop were applied…
If I say “NO” then ALL the fx are applied to the non-mask area…
grrrr…
