First: thanks to AntcuFaalb for the idea of using the grainplate; kudos!
I used a grainplate on The Arrival, and final result is good, in particular because there were almost no grain in the BD I used as source...
I added a grainplate also for the replacing shots of AVP:R taken from the DVD, to be similar to the BD.
Visit fanres.com and sign up; there are very interesting topics there, and I don't exclude to write an article about grainplate sooner or later!
