Hi again.
youre in a bit of a corner here as this is a student / school relationship rather than a normal producer / studio/commercial relationship.
If it were the latter and on a commercial footing then the whole handling would be totally different with correct archiving and back ups in place, and complete access and involvement for the dir, prod etc.
As it seems to be the former, I dont see you have much of a “whip to crack” so its difficult.
Good luck with it
