this is anecdotal so i don't know how to use it according to my son in law currently a staff crew member on grimm they use three cameras running two at nearly all times one on a railed dolly and one low probably on a so called sawed off or else on a high hat tripod a third hand held on steadycam is added as needed however this is not the or classic cameras on pedestals rolled around a studio floor for a standard multi camera sitcom shoot on grimm the setups are completely custom for each sequence however when shooting all digital on arris recording costs nothing so they can get quick coverage and footage that would task an old style production's film budget he says they will sometimes shoot pages a day given the quality of the lighting and coverage this is astonishing to anyone used to the obsolete hollywood procedures
