2 . How much memory of SSD need for 180 minutes feature film?
3 . Is apple OS with final cut pro enough for digital negative editing? if how much memory of servers need for editing?
4 . Shall we do post production at the cheapest rates for digital negative or footage of black magic cinema camera, if any tell?
