I am a Cinematographer on a feature film that we're going to start filming in September on the ARRI Alexa EV camera. We have the SXS cards and can max film in ProRes 4444. My question is, is it worth trying to find faster cards and then film in ARRI raw? Or do I get almost the same quality out of the ProRes 4444. The film is properly going to end up on a DCP 2K or 4K.
We are setting the camera up fro 16:9 full and then use a 1:2:35 mask to frame after.
